BRAND MODEL Chassis KEYWORD SYMPTOM CURE  
Sony KV36XBR250 AA-2W 16X9 mode Customers DVD player always plays back in 16X9 mode. Customer has JVC DVD player. Disc plays back in 16:9 customer selects 4X3 mode on their DVD player but TV stills displays 16X9. The JVC DVD player puts out ID signal even when no 16X9 is available. When the Sony TV detects this special ID signal it automatically puts the TV in to the 16X9 mode.  Compression Mode. Customer must now select  modes manually on their DVD player. This auto  feature can be turned off but only in the Service Mode. Change ID7 from 9  to 8. This is the No Auto V. Customer must now select modes manually on their DVD player.  
Sony KV32S40 AA-2 A.C. Hum KV32S40 serial 9028282 that has a low  level audio hum in the video input or tuner mode.  Looked in the FPR on web site but could fine nothing on the subject. The hum is at 60 Hertz The hum is a result of magnetic flux from the vertical deflection yoke. The 60 hz is radiating into the low level audio circuits through inductive pick up from lead dress and ground loops. To minimize these Remove JW086 and JW1007.Add 22AWG wire from JW270 to ground side of R477. This wire should be on the top side of the A-board and routed to following the audio signal lines from IC1401 (audio processor) to the amplifier IC1461.  
Sony KV27V66 BA4 A.C. hum Unit has a slight 60 Hz buzz in the speakers.  When in the external input mode and no signal applied the hum is evident. I asked tech to check to see if the upgrade listed in CSV #397. Jumper are present in the correct spots of the "K" board. Tech can measure 9.6 volts buzz at speaker terminals. However with the speakers disconnected the customer still claims to hear the 60 hz buzz. It this is true the tech needs to look into the deflection yoke for a cure the  buzzing. By putting pressure on the yoke, the tech can try to eliminate the vibration in the yoke assembly caused by loose laminations.  
Sony KV27V10 AA-2 AC leakage claim KV27V10 serial 7104657.  When the CATV rep was out a few days ago he plugged in the set in to wall and when the prongs made contact with the AC wall outlet a small spark was seen. The CATV rep exclaimed,  "The television is a fire hazard, and you need to call for service!" He left the set unplugged and we went out on this day. Our tech plugged in the set and found the set did have a spark as soon as the set was plugged in the AC outlet. This is perfectly normal because this chassis has to fully charge 2 820 mfd electrolytics in a voltage doubler configuration. This causes a tremendous amount of in rush current that may draw several amperes until the filters are charges up. This will cause a contact arc the moment the set is connected to the AC line. This set poses no more fire hazard than any other electrical device that plugs into the AC outlet. We also performed an A.C leakage test on the chassis and found that it was less than .015 volts measured at the customers ground connection and neutral.  
Sony KV32V40 BA4 acoustal vibration KV32V40 serial  Unit has an acoustical vibration on certain frequencies. Tech will need to go out with an variable audio tone generator to see where the source is of this mechanical vibration. Once found the tech must apply a special tape to the mating surfaces of the  cabinet parts that are vibrating as stated in bulletin 244R1. This bulletin does not actually apply to this model but the approach to the repair is the same. Part # of the tape necessary for this job is 7-632-661-51  
Sony KV27XBR10 FN AFT KV27XBR10. Serial 7009564. Unit has AFT drifting as soon as the channel is addressed. It never stops the AFT search Unit needs to have the IF/Demodulator module removed from it's shielded compartment and resolder all the adjustable tuning transformers. The AFC coil/transformer has ring fractures around the pins that protrude through the circuit board.  
Sony KV27V40 BA4 all snow KV27V40 Unit will not change channels. The number changes but the set will only display a all snow image.  Tech replaced the tuner and it did not solve the symptom. Tech needs to check the SDA And SCL  lines to the tuner.  When the set is on the Clock line at the tuner has a pulse but the SDA is Low. No data pulses. Unit had a scratched trace leading to the tuner assembly/ Jumpered trace and tuner now runs correctly.  
Sony KV32V25 AA-2 arcing KV32V25 serial 7036251. Unit has an arcing inside the flyback transformer. Tech replaced the transformer now the unit has a bright band at the top of the screen. The tech replaced the jungle "IC without effecting the symptom Tech noticed the +15 volt source was lower than expected. It was only 10 volts. It is not unusual. The voltage is normally 12 volts. What the tech was missing is the -15. This voltage must be there in order for the set to have any vertical sweep. D530 was shorted and open R536 the 0.47 ohm current limitter.  
Sony KV32V26 AA-2 arcing KV32V26 serial 8019814. Arcing in the neck off CRT Tech will need replacement CRT A80JYV51X  
Sony KV35V76 AA-2 ARCING KV35V75  CRT is arcing in the neck The CRT is bad.  
Sony KV35XBR48 AA-2 ARCING KV35XBR48 serial 9014229. TUBE ARCING IN THE NECK unit will need CRT  A89LJT80XZ  
Sony KV36XBR200 AA-2H arcing  KV36XBR200  Unit has an intermittent arc over that will shut down the television. The  best way to tell if the arcing is related to the HV lead which may be breaking down is to use a high voltage probe. Connect the ground to the CRT ground and run the tip of the high voltage probe over all high voltage connections & wires. If an arc is drawn to the probe tip this would mean that a break  down in the insulation has occurred. This test revealed a break down in the High voltage connection at the High Voltage anode button. The silicone sealant did not seal between the HV button and HV cup. Cleaning the area around the anode button, replacing the anode cap and resealing the connection with high voltage silicone sealant.  
Sony KV27S20 AA-2 Audio Sony KV27S20. Unit has a low pitch whine in the left audio channel. Problem is best heard in the video input mode with no signal put to the input. It can be seen with an oscilloscope on one of the output pins of IC1401 but not on the input. Part number is 8-759-369-39. IC1401 corrected the trouble.  
Sony KV27S36 AA-2 audio Sony KV27S36. Unit has choppy SAP audio. Stereo 0.K. All SAP, Stereo, and mono functions come from the Tuner assembly and nowhere else. If a problem exists for the S.A.P. feature all circuitry relating to the feature is replaced when the tuner assembly is replaced. Recommend the Tuner/IF/MTS decoder assembly. Replacement corrected the symptom.  
Sony KV27S45 AA-2 AUDIO KV27S45 serial 8046950 Unit has a very rapid change in volume when increasing the level from minimum to 4 notches above minimum Tech needs to add a resistor in parallel with R432 to effectively reduce the value of R432. This changes the voltage divider ratio to the volume control circuit and makes the volume circuit more linear in operation.  
Sony KV27V65 AA-2 AUDIO Audio level adjustments will not increase in a linear fashion, instead the audio will increase rapidly in the first 1/3 of the bar graph. A new microprocessor is available for this unit. It is part number T-998-600-32. It replaces the original IC001 which was M37273MF-251  
Sony KV27V65 AA-2 audio Sony KV27V65 Sound does not ramp up correctly. Seems to get very loud as soon as the volume gets higher in a very short time I had tech get into the ID codes and reset ID2 from 239 to 175 and ID 4 from 130 to 194. Then initialize the EPROM . Set returned to normal operation  
Sony KV32S65 AA-2 audio KV32S65. Serial # 8014575. Sound and picture is fine but when the fixed or variable audio out is connected to an external audio amp and the set is muted a loud pop is heard in the right channel. I had the tech try to measure if there was any DC voltages that resided on the Variable audio output connectors. There was "4.5" volts on the Right channel and "0" volts on the left channel. When the "Mute" transistors on the variable line triggered they pulled both lines to ground. When the external amp was connected to this circuit the input capacitor for the right channel charged with this 4.5 volts. We still had audio on this line even though it was at a 4.5 vdc potential. But when the Sony muted, the input capacitor inside the Big External amp discharged and caused a tremendous pop.   C172 is a .47mfd used to decoupling the audio from IC101 the Variable audio control IC. This capacitor had 4.5 vdc on each leg measured to ground. Removing the capacitor and measuring the DC resistance across the cap measured 175 ohms. Replacement of the capacitor corrected the symptom.  
Sony KV32XBR10 ANU-1 AUDIO Unit has no audio 8-741-592-2 (8-741-100-56) original  number SBX1592-02 corrected the symptom  
Sony KV27V40 BA4 audio KV27V40 8024539 Unit goes looses audio on voice peaks or when ever the volume is moved to a high position the volume will mute for about 1 second When Isolating the mute transistors I find that removing the Coupling capacitor C223 stops the muting action.  This capacitor appears to be monitoring the B+ used for the audio output IC.  We do have a slight fluctuation of voltage  0.3 ~ 0.5 volts to the audio output when the volume is maximized out. this is coincident to load variations of loud to soft sounds However when this variations reach the 0.5 volt deviation the audio will mute. R210 is good and so is Q204. We replaced C223 with a new one and even tried to reduce the value to 1 mfd but we still get the same muting effect on voice peaks. IC401 has been replaced on an earlier visit with no changes in the symptom. It is unknown why this is causing this symptom.  
Sony KV27V65 BA4 audio KV27V65. Unit has a 60 hz buzz in the audio will near minimum level is selected Tech needs to add a ground wire to the ground side of R544 to the ground under the flyback transformer  
Sony KV27V16 BA5 Audio Unit has no audio, but when entering the service mode the audio returns. After resetting the EEPROM the set enters the reset mode normally but the sound is gone again. Tech replaced IC001,IC003 and K- board, without effecting the symptom. All had checked all voltages on the IC301 and everything looked normal. Out of desperation the tech ordered the IC301 and changed it. Tech changed the jungle IC301 and it fixed the problem.  This answer might save someone some time? The tech was very happy to let this baby go home after wrestling with it for many hours! Thanks to Jesse Mann  (L. A., California)  
Sony KV24FS100 BA6 Audio Problem: Volume control doesn't work. Volume bar OK just volume stuck in high / loud audio. Solution: Replace IC404 - audio output. Sony installed wrong IC. Instead of AN17820A they installed AN7125Z. The correct part # is 6-701-104-01 (AN17820A) I had already three units with the same problem. All of them KV24FS100 (BA6), serial number 4108227,4108225,4108261.  
Sony KV32TS27 LN1 audio KV32TS27 7039676 Unit has an intermittent squeal in the audio when trine to receive a stereo broadcast. Tech needs to replace the Audio IC SBX1627-11  
Sony KV32XBR70 ANU-1 Audio Unit has"Garbled", or "Noisy", or "Distorted", or "Static", but what is ISN'T is "NORMAL". Problem traced to the SBX sound package that might cause similar symptoms, and IT has been decreed as NLA by Sony. It's the SBX 1593-01 (Sony # 8-741-159-30). Wouldn't you just HATE to have to trash a nice Sony TV because you can't get a part to fix a Sound Problem? Well, one of our readers has come forth to tell you of a way to bypass this circuit. To bypass the module: Use two 4.7@50 capacitors and connect the (-) side of one cap to pin 5 on the MTS module and the (+) side to pin 4 on the DBX module. Take the second cap and connect the (-) side to pin 6 on the MTS and the (+) side to pin 5 on the DBX module. This should give you clean sound but you may not have the fullness that the board would have given you."
Well, a "Lack of Fullness" is certainly better than a "Lack of Sound" which is what the customer had before the bypass. 		 
SONY KV36FV27 AA-2 Audio Missing Unit has Wireless head phones. Unit has audio through he main speakers but not through the wireless headphones Checking around the T board we found that the B+ to the board was missing at connector CN401(4). This should be 9 volts. There are no shorts on this line to ground either. But checking at the AK board we found a PNP switch transistor Q451 with ring fractures around the pins. Resolder the transistor corrects the symptom.  
Sony KV36FV75 AA-2 Audio Missing KV36FV75. Unit has no audio. But also has no OSD stating "Main" or "Stereo" Main picture is fine. ID codes are 0=25, 1=55, 2=47 3= 0 , 4= 155, 5 =143, 6 =6,  7=0 which is correct. Initializing the EEPOM did not correct the trouble. Tech will be returning with a Manual  
Sony KV32XBR10 ANU-1 Audio Missing KV32XBR10 Unit has no audio Product has a defective MTS audio controller part # 8-741-592-2 (8-741-100-56) original  number SBX1592-02 corrected the symptom  
Sony KV27S42 BA4 AUTOPROGRAM KV27S42. Serial 411756 Unit does not autoprogram. When using direct access to change channels the set will execute channel change but takes nearly 4 seconds before it will lock in. channel the set will access it All TV's that use autoprogramming must have 2 inputs to the CPU that will tell the CPU it will store a channel in its memory.  These inputs are AFC crossover voltage & presence of horizontal sync. The AFC get the frequency of the video carrier centered in the passband of the IF. The horizontal sync is used to validate the signal is a non-scrambled video signal. This television did not have the Horizontal sync from IC010, an HSYNC-SW.  This device is used to detect valid horizontal sync from both tuners. There was composite video at IC010(1) but there was no output on IC010(7).  Neither one of the tuners had good channel lock in characteristics. Suggest the tech check out IC010. IC)10 had a contaminate under the chip. It was a light brown compound that covered all pins under the IC. The contaminate was removed and the old Chip reinstalled and the set operated normally.  
Sony KV35XBR35 AA-2 B&W Tracking KV35XBR35. Unit has color temperature error in the YUV input mode only According to Sony tech support there is no adjustment for this input. Refer this customer to Sony customer affairs.  
Sony KV27S22 AA-2 BRIGHT RASTER KV27S22 serial #  8102548. Unit goes to a bright blue screen with retrace lines then shuts down. Unit has a defective CRT. When unit is able to turn back on again the set will sometimes be in the video input mode.  
Sony KV35S26 AA-2 CHROMA KV35S26 Unit has the tint phase shift and color lock up problems only on the Hughs satellite receiver. VCR and over air signals have solid color lock up. This symptom acts like it is a problem with the satellite receiver. Inside the satellite receiver there is a NTSC encoder which injects the 3.579547 MHz color oscillator signal in the video. If this oscillator is too far off frequency it will not phase lock with the 3.579545 MHz in the television. This is a software problem with the Satalite receiver. A software download will be available to all receivers in Late 2000 to correct this problem.  
Sony KV35S26 AA-2 chroma Unit has random chroma phase shifting. The tint will vary radically. NTSC color bars are not stable. "Barber Polling" effect of colors on bars. Suggest the tech look very close to the connection s to IC351(4) This the  Chroma AFDC filter. Components R354, C354, & C355 are in the AFCFIL circuit. It is possible the trouble is a Jungle IC but Before replacing it is recommended to check the aforementioned components first. Note: when checking the components it was found that C354 has glue touching each end of the device. The glue effectively changed the value of the device. Cleaning the glue and reinstalling the device corrected the problem.  
Sony KV35XBR200 AA-2 CHROMA KV36XBR200  When the customer is using the RF input labeled VHF/UHF the set will picture will lose  chroma intermittently. But when using the AUX input the chroma is solid and does not vary. The tech replaced the RF switch without effecting the symptom. The customer is using two different RF sources. Cable TV and a satellite dish. The CATV is being feed into the RF input labeled VHF/UHF and the satellite is fed into the AUX input. It appears the tuner does not correct the AFT when two different RF sources are used. The channel will has to be readdressed again for any AFT correction to occur. Suggest the customer used the satellite in the S-video and separate video input mode. In his present configuration the customer is loosing all stereo reception, and all high frequency detail over. This corrected the symptom.  
Sony KV35XBR48 AA-2 CHROMA Unit is connected in to component video input mode through a DVD player. The picture has a predominately green picture When operating  a different DVD player the symptom  is the same. There is no cure to this phenomin from Sony at this time  
Sony KV27S15 AA-2 Chroma Missing KV27S15 Unit has no Chroma. Black & white is OK. Also no Chorma while using the PIP. Sound and On Screen Display OK. Initializing EPROM does not change the effect. Scoping the first place where the chroma signal can be readily available is on the PIP module. They are marked "C IN" & "C OUT" on connector CN501(1 & 5). We have chroma going into the PIP board but nothing coming out. Jumping these pins together with a 1 mfd capacitor caused the color to return, as long as the capacitor was in place. Unit has bad PIP module.  
Sony KV32XBR48 AA-2 chroma PIP missing Sony KV32XBR48. No chroma in PIP X3304 0n PX board not soldered (PIP)  
Sony KV27V66 BA4 clock loosing time KV27V66 serial  Unit looses 3 minutes a in 2 weeks on the internal clock in the television The clock should remain within 7 seconds + or minus in a seven day period. The time base is from a crystal and the count down circuit inside the microprocessor. Suggest the tech replace the crystal, and the two padding capacitors in the crystal network.  
Sony KV27S20 AA-2 CLOSED CAPTION KV27S20 serial # 7042141 Unit will not operate in the closed caption mode if using the DVD player. However if the television operates in the tuner mode for over the air telecasts, closed caption works fine. Tech needs to order IC001= T-935-001-61 per bulletin R329R1. After replacement the tech will need to enter the tech menu and select "CRIW" and change it from 15 to 3. Also check the "LBLK" must be 7, "RBLK" must be 7 and "HBSWO" must be 0.  At this point save the new data and exit the tech menu.  
Sony KV27V20 AA-2 CLOSED CAPTION KV27V20  8015729 No closed caption on premium channels  The tech needs to set the ID codes to the following ID0=25, ID1=19, ID2=47, ID3=0, ID4=27, ID5=3, ID6=0, ID7=0. If these are OK then the tech will need to replace the IC001 with an upgraded version per bulletin 329R1 Original generic # is CXP85640-004S, the new generic # is CXP856P40S-1 part number T-935-001-61  
Sony KV27V20 AA-2 CLOSED CAPTION KV27V20 serial 8015729 Unit does not have closed caption on premium channels See Bulletin 329R Original CPU CXP85640-005S The new device is CXP85640-006S  
Sony KV27V20 AA-2 CLOSED CAPTION No closed caption on premium channels  The tech needs to set the ID codes to the following ID0=25, ID1=19, ID2=47, ID3=0, ID4=27, ID5=3, ID6=0, ID7=0. If these are OK then the tech will need to replace the IC001 with an upgraded version per bulletin 329R1 Original generic # is CXP85640-004S, the new generic # is CXP856P40S-1 part number T-935-001-61  
Sony KV27V20 AA-2 CLOSED CAPTION Sony KV27V20.unit has intermittent symptom of closed caption coming up on screen. Cust claims they cannot turn off the closed caption option. Unable to see any problem with circuitry, and ID codes are correct. All appears normal. Setting all CC1 ~ CC4 and teletext 1 and 2 to the "Minus" option this effectively shuts off the closes caption feature. Instruct customer to operation od CC modes.  
Sony KV35V75 AA-2 CLOSED CAPTION KV35V75 9006691 Unit does not have closed caption on premium channels Original CPU CXP85640-005S The new device is CXP85640-006S CPU was replaced and did not correct the symptom.  
Sony KV32V15 AA-2 color banding Sony KV32V15 serial 9013716 AA-2D Unit has horizontal banding of purple and red at top of screen. If the color was reduced the banding would disappear. Color bar did not have a normal appearance Resistor R354 was not soldered in correctly. The resistor is in the Color AFC circuitry. It had a .15 ms ripple on it causing a phase shift in the chroma in the first 4 to 5 inches on the picture. Problem was caused by a glue used to secure the surface mounted resistor. The glue prevented a good connection of the resistor to the pad. Cleaning the glue away and resoldering corrected the symptom.  
Sony KV32XBR76 FN Color Poor KV32XBR76. Unit has poor color registration but color bars appear near normal. But when cross hair pattern is put up on the screen there are no blue vertical line. There are red and green vertical line and all three colors of horizontal line. This symptom is a result of a high frequency loss. The ability for the amplifiers in the B drive to turn on an off rapidly is a direct result of how high the bandwidth is. In this case the three outputs of the Jungle IC301(20,22,&23) had the typical signal when viewed on an oscilloscope. All three outputs had the same vertical spike in the center of the horizontal line  on the oscilloscope scope. Waveform showing the cross hair pattern was the same value on all three outputs. However on connector E1(5) the signal was noticeably lower. R359 the supply resistor for Q325 had increased in value to 3.76K form 1K. Replaced R359 (surface mount resistor) corrected the symptom.  
Sony KV35XBR48 AA-2 color wrong KV35XBR48 serial 01901543. Customer using this television on a DVD player and has it connected through the "YUV" inputs. The gray scale is favoring the  green color temperature even if no color is present on the screen. Playing back the same signal in the Composite input or the S-video input the color temperature is normal with normal black and white tracking. It is thought that a separate black and white tracking or RGB drive adjustment in the YUV mode will solve this trouble. According to Sony there isn't any drive adjustments in the YUV mode. This symptom shows up on another Sony television of the same model. Sony claims this is a normal function and there are no plans to address this issue with Sony Engineering. There is nothing wrong with the Television. Unfortunately it is operating as designed.  
Sony KV32XBR45 AA-1 CONVERGENCE KV32XBR45 convergence is way off in the horizontal direction Unit has an open R789 a 18 meg 1/2 watt resistor for the Horizontal static convergence. The tech will have to make a resistor out of 3, 6.2 meg resistors.  
Sony KV32XBR45 AA-1 CONVERGENCE KV32XBR45 Unit has convergence of all vertical lines are displace horizontally. Tech replaced the CRT without authorization. This did not solve the symptom Suggest tech look for R789 and see if it is open  It is on the on "C" board.  It The value is around 10 meg. There are two different chassis and CRTs used for this model.  If they have the older chassis type that requires H stat convergence (CRT board has H stat control) they  need to order the older CRT as  per the manual. If newer type (No H stat) then the new CRT as per Service Manual supplement -1 is needed.  CRT  8-733-743-05 The H Stat is done using the Yoke ring magnets.  I have attached the two Service Manual supplements, and the SB325R1.  
Sony KV32XBR45 AA-1 CONVERGENCE KV32XBR45 Unit has sever Horizontal static convergence error. Tech replaced the CRT without authorization. This did not solve the symptom. Suggest tech look for R789 and see if it is open  It is on the on "C" board.  It The value is around 10 meg. There are two different chassis and CRTs used for this model.  If they have the older chassis type that requires H stat convergence (CRT board has H stat control)  I have attached the two Service Manual supplements, and the SB325R1. However none of them have show this resistor. We were able to install a resistor in this unit that was a two 10 megs in series. Trimming the value by adding another 10 meg in parallel with one of the other 10 megs. we were able to converge the set. Original part was not available.  
Sony KV32XBR45 AA-1 CONVERGENCE Unit has mis-convergence of red and blue vertical lines. They are displace horizontally. Tech replaced the CRT without correcting the symptom. R789 open H-state not operational.  What I'm finding is a resistor that appears to be open on this "C" board It is R789 The value cannot be read nor is it listed in the ESI software parts list. Trying another value from 10 to 20 megohms. This resistor is in the ground return of the H-stat resistor that is installed in the CRT. Tech needs to try different values to try and make this set converge horizontally. This TV converged with a 10 megohm resistor.
  
Sony KV32XBR45 AA-1 CONVERGENCE Unit has nis-convergence of red & blue vertical lines which are displaced horizontally. Tech replaced the CRT. This did not solve the problem. Suggest tech look for R789 and see if it is open  It is on the on "C" board.  The value is around 10 meg. There are two different chassis and CRTs used for this model.  If they have the older chassis type that requires H stat convergence (CRT board has H stat control) they need to order the older CRT as per the manual. If newer type (No H stat) then the new CRT as per Service Manual supplement -1 is needed.  CRT  8-733-743-05 The H Stat is done using the Yoke ring magnets.  
Sony KV27V22 AA-2 CONVERGENCE KV27V22 serial # 8051260 will not converge the bottom red green or blue horizontal lines Unit has over 6 permaloy magnetic on the CRT bell in the area of the bottom of the yoke. This is not a good sign. It is also a rebuilt CRT. We are not going to place more Permaloy strips on this CRT. It needs replacement.  
Sony KV27V40 BA4 CONVERGENCE KV27V40 Unit has vertically skewed convergence. Center vertical convergence is Skewed with red skewed counter clockwise by 0.5 inches and blue skewed clockwise by nearly the .05 inched. Green lines are straight. Problem is caused by a defective CRT.  
Sony KV35S40 AP CRT Unit has preglow at the instant the television is turned on. The preglow shows in the lower left and right hand corner and stays until the raster appears. This phenomena is normal and is caused by the IK pulses that are produced at the instant of turn on. Even thought the cathodes are not completely warmed up there will be a slight amount of beam current produced by just the IK pulses. Since these pulses are at the top portion of the tube or on the curved funnel portion of the CRT this symptom is common and is not considered a defect in the CRT.  
Sony KV32XBR76 FN Cycling on an off Unit cycling on and off as soon as the set is plugged in. This set was an older unit has  seen many hours of use. The tech was instructed to ESR all electrolytics in the power supply. After ESR'ing all the electrolytics we found that C662 in power supply was open. Its ESR was infinite. Value was supposed to be 220mffd@ 35 vdc.  
Sony KV32TS36 AA-1 Dead KV32TS36 unit is dead.  Tech replaced Q601, Q602, & R607. Then put full power to the set and blew out all the same components again. I had the tech check the Secondary of the T605 for shorts. Also check to see if the horizontal output is shorted. Did not find any shorts in the horizontal but the driver transformer had small ring fractures around the secondary pins. Resoldered these pins and started the set up again with a 40 watt light bulb in place of R607. The set operated with reduced secondary voltage and cycled on and off at about a 3 second rate. During the cycling the collector signal at Q501(C) was normal. Replaced the light bulb with a new R697 and the set ran fine.  
Sony KV32TS46 AA-1 Dead Unit was dead. has shorted horizontal output and shorted Q601, & Q602 components in power supply replaced. After replacement unit will turn on but still has no secondary voltage output of power transformer. All relays click but no high voltage. Has sound. Tech needs to check the condition or RY602. RY602 is the switching relay that turn on and off the set. The relay is "HOT" switched. In other words one side of the relay is connected to  power oscillator output that runs nearly 350 vac Peak to Peak at 90Khz. Once the relay is closed this energy is placed across the power output transformer and provides the drive necessary to produce the B+.Measuring the input voltage of the relay to "HOT' ground found it to be 150 volts DC mode.  But on the other side of relay we has 3 volts DC mode.  Unit has defective RY602 relay.  
Sony KV27V65 AA-2 Dead Unit  is Dead Tech replaced the IC601 and R607 and the Flyback, but when power was reapplied the set destroyed the power supply again. Unit had a blown IC601 and R607.  Tech had failed to check the condition of the Power supply output for the 135 vdc source.. It was discovered there was a 1.2 ohm short to ground caused by a shorted protect diode in the secondary of the power supply.  I cannot stress enough the tech needs to check all loads on the secondary of the power supply for shorts, and use a variac to  start up all power supplies. All parts changed earlier are destroyed and need to be replaced again.  
Sony KV32S40 AA-2 Dead KV32S40  serial 8001469. Unit  had the power supply IC601 shorted and open R607. Tech replaced these components and it shorted out again at the instant the television is plugged in. I never recommend that after replacing these components in the power supply that the set have full line voltage applied  to it. The odds are very high the new components will be instantly. Suggested the tech use a variac to do these  tests. This power supply should start running at 10 vac as a line source. The current should never go above 100 ma during a no load test. Max 800 ma during a normal load. When running this power supply at 15 volts the current was surging to over 200 MA. Checking al the loads on the secondary found no obvious short circuits. However when checking the capacitors in the primary we found C610 has internal resistance of 470K, There should be no internal resistance. Replaced C610 and restored normal operation. Suggest that C609, C610, C611, and C612 be automatically replaced when this happens.  
Sony KV32S40 AA-2 Dead KV32S40 Unit will run for several days then it will short the horizontal output transistor and destroy the power supply IC601 This product was brought into the shop where the set was operated with the CRT disconnected for approximately 100 hours continuously. It ran fine. But 6 hours after the CRT was connected the Horizontal output and power supply self destructed again. Unit has defective CRT Suggest the tech replace the CRT  
Sony KV32V40 AA-2 Dead KV32V40 Unit was originally dead. Q502 was replaced. Now set has a sever over scan of horizontal sweep. Collector of Q512 only 2 volts Q512 was shorted. L511 is burned and needs to be changed, along with D504 D503, D502, C511, C513, and L511. After replacement of the components the sweep was still excessive. When using an oscilloscope on the IC351(31) the E/W pin out we found  6 volts DC, and no 60 HZ parabolic wave form. If this E/W output pint was touched to ground through a 270 ohm resistor the picture narrowed up to a an almost normal width. Product had defective IC351.  
Sony KV32XBR48 AA-2 Dead KV32XBR48. Originally dead with shorted IC601 converter IC and horizontal output transistor shorted too. The horizontal drive looked odd, but this was not the problem. Checking the Collector of the Horizontal output transistor the retrace period was running in excess of 20 microseconds not the traditional 11.5 microseconds. Closed  inspection was found the deflection yoke leads  inside the connector were loose and the crimp for the wire to the horizontal winding were not making contact to the terminal inside the connector.  Cleaning the terminal and prepping the connection was necessary because there was evidence they were burned by the voltage drop in the poor connection .

Closer inspection found the deflection yoke leads inside the connector were loose and the crimp for the wire to the horizontal winding were not making contact to the terminal inside the connector.  
Sony KV35S26 AA-2 Dead KV35S36 serial 9027801 Unit goes dead after 10 minutes after the power supply was repaired.Q601 & Q602 were not running hot they just shorted. They were replace 4 times. Each time the transistors lasted 10 minutes and in 1 case 1 week. After running the television for over 1 hour with the CRT disconnected It was determined the power supply, deflection, and horizontal deflection were all working. It was further decided to change the CRT needs to be replaced.  CRT fixed the unit.  
Sony KV36FV1 AA-2 Dead KV36FV1 serial 9029271. Unit is dead. After talking to customer they explained that they had a power surge caused by a car hitting a power pole. The set was completely dead. VDR602 was noticeably burned up. Cutting this device our of the circuit found that it was open. However the device is connected in the circuit like a metal oxide varistor. It should measure open since it is in parallel with the A.C. Line.  It was discovered that no other shorted components could be found in the primer of the power supply. Main line fuse WAS NOT BLOWN! Checking the raw AC voltage on the AC Line filters T601, and T602 find that we have no AC voltage on the output of T602 but present on the input side. Isolating the  open coil and removing the defective VDR602 allows the set to turn on and operate correctly. Tech will need to replace T602 and VDR602.  
Sony KV27XBR15 ANU-1 Dead Sony KV27XBR15 ANU-1 chassis Unit is dead. Unit had all 3 regulators loose. All had ring fractures. Once resoldered the set still did not turn on because of a short to ground on the 135 vdc line. Horizontal output is also shorted. ?This unit requires a modification to the horizontal output section KIT # T-998-566-41. This Kit consists of a 2SC4927 and a .68 ohm resistor that must be used in the emitter of the horizontal output transistor.  
Sony KV27S40 BA4 Dead KV27S40 Unit is dead. Will not turn on LED flashed 5 time . The set will latch the relay but will not develop secondary voltages from the main power supply Checking the secondaries of T603 we could not find any short circuits on the se The needs to connect a variac up to the television and supply 18 volt AC. A jumper need to be installed across the contact connections of RY602 in the A" board.  
Sony KV27S45 BA4 Dead KV27S45 VDR5050 Unit dead. Inspection of the chassis discovered there is no stand by voltage. Inspecting the "E" board found that the fuse F5050 was open and the  VDR5050 had a chunk of material  blown off of it. VDR5050 is  metal oxide varistor. It is in parallel with the AC line voltage . It appears the customer had a AC line source that blew the MOV, then the fuse. Checking Q5001 we do not find a short between Drain and Source. Suggest the tech remove the MOV and replace the fuse and try operating the set. It operates fine. Suggest the tech replace the MOV, but disable the television until the MOV can be replaced, since the MOV is a Protection device in the event the Power surge returns. NOTE: It was discovered the VCR was also dead which not was not evident at the time of the call. This confirms the power surge theory.  VDR5050 = 1-801-074-41 F5050 =1-576-193-11 6.3 amp @ 125vac.  
Sony KV27V40 BA4 Dead KV27V40 8112963 Unit is dead. Only the Timer LED flashes. There are apparently no shorts circuits on the secondary of the  main switcher supply. However when trying to discover why the IC601 was shorted we could not find any evidence of line surges that might have shorted the VDR601 or open R618. But when checking the secondary of the Flyback transformer at the outputs of D560 and D561 we found nearly 4.6 ohms from the +13 to the -13 volt source. Floating IC541(2&4) removed the shorted condition. Unit has a shorted vertical output IC541 shorted from the +13 volt to the -13 volt if IC541(2 &4)

Sony KV24FV300 BA6 DEAD This TV RAN and for approximately ten hours and then shut down. The standby supply is running because the relay RY600 will latch, But RY501 will not latch. LED in front is blinking 4 times then stoppsWhen measuring the presence of B+ at IC600(18) referenced to hot ground, it was missing. Main supply was not oscillating. All conmponents Q600, Q601 are not shorted. B+ at Q600(D) was 345 vdc. Checking R640 a 1K resistor found it to be open. It was suggested that R640 and IC600 be replaced. IC600 Pn# is 8-759-670-30. Replacing the devices corrected the problem.  
Sony KV24FV300 BA6 Dead IC600 and R640 blown. Here is the problem; An arc occurs from the CRT dag to the heatsink of Q600 because it sits so close to the Dag. The heatsink is isolated from ground so the arc has no where to go but to the closest point to the heatsink. This point is IC600(18). The arc kills IC600 and subsequently burns up R640, a 1K at 1/2 watt resistor. Replace the defective components then add a 100K resistor from the heatsink to ground. Directions are located at this link. http://wa6ati.home.mindspring.com/BA6-IC600-Countermeasure.pdf  .  
SONY KV32XBR36 FN Dead Unit will not power on. Monitoring the 17 vdc stand by supply we find the voltage running at 4.6 volts. One of the primary filters on the 17 vdc standby supply C662 a 220mfd @ 35vdc was open.  
Sony KV32XBR76 FN Dead Unit will not turn on. No high voltage. Measuring the condition, D1409 is shorted. The problem is caused by D1409 on the A Board shorting. Problem caused by an intermittent B+ regulator on the G board, IC651, 1-809-524-11. Replacement resolves problem. We have seen a number of these units lately with D1409 shorted. Often it is simply ring cracks on IC651 causing the problem. This unit did have a loose solder connection on IC651(1) but it did not drop the voltage down enough across D1409. The voltage was always 36.6 volts across a 36 volt Zener diode.  
Sony KV32XBR96 FN Dead KV32XBR96. Unit is dead and has no vertical sweep. R623  and VDR 602 burned up. Tech needs 8.2 ohm resistor to replace. Tech does not have 8.2 ohm in his stock. However he can make an 8.2 ohm by paralleling a 10 and 47 ohm resistor. This will create a 8.24 ohm resistor.  C531 vented is Connected to R881.  
Son KV32FS320 BA6 Dead When checking the power supply for the horizontal output we found that the B+ would jump to about 55 vdc then drop off. Measuring all the secondaries we found that all the B+'s were off by 50 to 60% then the power supply shuts off but does not loose the Raw B+. Checking around IC600 we found normal B+ voltages but the ones on IC600(2&3) were bouncing and very unstable. Further checking on the secondary  bridge rectifier D611 we found the one of the diodes in the bridge arrangement was shorted. Only use the original replacement. This is not a low speed device. It is an ultra high speed bridge rectifier and it looks like a standard 60 Hz type. Sony Part # is  871906240

Sony KV36FV1 AA-2 FOCUS KV36FV1 Customer is running the television on a DSS satellite system. Customer claims the set looses focus in the picture when there is a lot of detailed movement. This is caused by the 10 megabit throughput limit of the DSS video  compression format MPEG3.  In order for the compression to work correctly the Digitization process only updates the data that is changing. Background data is not updated as regularly as the foreground data. Hence when everything must get updated. But the MAX Data throughput is finite. the entire video waveform will not be accurately represented, instead the smaller detailed portions of the picture will begin to have larger pixels so not to exceed the Max Data. This is why to the eye the set appears to loose resolution or picture detail. This is normal.  
Sony KV36FV1 AA-2 focus KV36FV1 serial 9046442 Unit has poor focus on left and right side of picture The set has a dynamic focus error. Tech needs to see if the Dynamic focus circuitry is running correctly. Also before any hardware is tested the parameters of HAMP and DCSF should be adjusted to see if the dynamic focus is effected. When adjusting these parameters the values get the best focus when each is mixed out to 60. The focus becomes poor 2 inches from the left side of the screen and 5 inches from the right side of the screen.  
Sony KV32FV1 AA-2H focus KV32FV1  Unit has poor focus on the left and right side of screen but OK in the center. If the focus control is varied through its range the sides will become in focus with the center out of focus. Since this set has the super flat CRT. It incorporates a dynamic focus circuit. In other words the focus voltage varies as the beam travels from left to right. Measuring the Horizontal parabolic wave form up to the input of the primary of the  DF transformer, we found the signal to be normal. We were unable to measure the voltages further because they were potentially focus voltage potential. The horizontal parabolic wave form enters the Flyback at the secondary of the DF transformer. Unit had defective flyback transformer.  
Sony KV36XBR200 AA-2H FOCUS KV36XBR200 serial 9023068Out of focus on the extreme horizontal edges of the screen. The last 3 inches have a noticeable focus error CRT...Attempting to move the focus control does not cause the area on the outside of the CRT to change focus. Unit may have Bad CRT.  
SONY KV32XBR45 AA-1 GEOMETRY Unit is trying to constantly adjust the vertical height and horizontal size intermittently. When monitoring the E/W Pin output of the M board the signal was very instable. It was decided to replace IC351 the Jungle IC. This corrected the trouble.  
Sony KV27S10 AA-2 GEOMETRY KV27S10 serial 723009 Unit has symptom every time the set looses power the geometry memory is lost VPOS, VSIZ, HSIZ. PAMP drop at least 10 points each. When resetting these values and writing them to memory the they will be erased as soon as power is removed Tech needs to replace the EPROM……. I002 corrected the problem  
Sony KV27V65 AA-2 GEOMETRY KV27V65 serial 8027393 Customer complaint is a slight geometry error or tilt  in the lower right hand corner of the screen. It causes a symptom of horizontal lines that are not perfectly straight. In this case the lines are elevated by at width of 2 horizontal lines. This television is operating within specifications. The geometry errors should not deviate  more than 1/8 of an inch across the length of the Horizontal line. Horizontal tilt can be no more than 1/8 of an inch. This television beats this measurements. There is nothing I can recommend to the tech to do to improve on the geometry of this receiver.  
Sony KV32S45 AA-2 GEOMETRY KV32S45 serial 8102913 picture is rotated clockwise by 1/4 inch. Tech claims this tube does not have a pix tilt circuit or rotation on the CRT bell Tech needs to break the bonding of the yoke ant reposition the yoke.  
Sony KV36FV1 AA-2 GEOMETRY KV36FV1 serial 9032273. Unit has a symptom of "Shoulder roll off". In other words horizontal lines are bent down on the far left and right side of the screen.  Tech needs yoke modification for the  yoke upgrade. Gave tech bulletin 387R2 relating to the shoulder roll off  
Sony KV32XBR200 AA-2H GEOMETRY KV32XBR200 serial # 9008075 .Unit has just had the new CRT with the attached yoke replaced today to correct the Shoulder Roll off symptom as described in Bulletin 387. However the new tube and yoke did not solve the vertical pincushion symptom Bulletin 387 did not mention a plate which was in the old deflection yoke.  The missing THL plate needed to be removed from the old yoke and placed in the same slot in the new yoke .  After following the new bulletin 387R1 we were able converge the set.
