Scenium HD52W140 ATC311 Shutdown When unit itr turned on the set goes to immediate shutdown. Close inspection of the power supplt/ deflection boards finds a resistor R14705 burned. In fom cases this resistor has burned so badly there is a hole through this circuit board. This resistor is located in the ABL portion of the flyback area. The cause of this resistor burning is because the High voltage distributioin block was shorted. This caused the 2nd anode voltage to be pulled to near ground and the ABL line to be forced to a very high negative voltage, thus burning the R14705. This TV is a modular replacement during the warranty perion. The tech will need to order the Power supply / Deflectoion board (258507) and the High voltage splitter (258512).
Scenium HD52W140 ATC311 Shutdown TV goes to bright white screen with retrace lines then shuts down. 200 vdc at cathode of CR14703(K) running at 130 vdc. C14703 on the deflection board is loose on the board. This is for the 200 VDC line.
Scenium HD52W140 ATC311 Video Freezing / Pixelation The picture will pixelate and or freeze on 480i sources including the sattelite sources. HDTV sources including tresstrial HDTV signals are OK. 480p from a DVD source is OK too. All video sources composite of component if they are NSTC (480i) are processed through the DM2 module. DM2 module is defective. Need to call RCA for authorization.
