Green light flikering


Replace all 7 capacitors in the DM Module on the DM Power Supply Board. If it is similar to the WS-65869 and WS-65513 it will have a metal enclosed DM Module at far left of chassis, looking from rear. About 4 or 5 connectors, screws, and Module slides out. Take top shield off. Take good notes or use digital camera or video recorder to make re-assembly easy. These capacitors are 1000uf@16 volts. They always check good, just replace them! After re-assembly plug AC in and wait 90 seconds or more (green Timer LED will stop blinking), then press Power button. If Timer LED doesn't stop, look for small pinhole (System Reset) and press switch with pen or small screwdriver, then wait for green LED to stop blinking. Then Power On TV.

Turn on the TV and only Timer light is on , no sound & picture


press the menu and input/device buttons both in together on the front of the set and hold for 5 seconds and then see if the set blinks a number of blink pauses and then blinks another number such as 2 blink pause 2 blinks which would be a 22 caode. It then repeats that code.
