The image processor is nearing death, most likely because the voltage from the power source is wrong. Open the tv and test the source, replace all aged parts starting with the capacitors and finally check the voltages at the processor.

SOURCE: tv sound but no picture

The backlight inveter board may have gone out ,or the power supply is not working to supply power to the inverter board, those are the two places to look.

SOURCE: TV Turns on picture comes on for 30 seconds then

This is not the fix for this TV. I guarantee that none of the capacitors exhibit the common bulging characteristics of a faulty capacitor. The common answers to everyone's questions are to replace the capacitors. Most likely the culprit is the inverter board.

Turn on the TV, red light stays on, picture goes blank after a second.


I have the same problem. Factory reset did not help (hold Vol-minus on set and menu on remote five seconds, then unplug). Can there be something in service mode that would help?

My Westinghouse 36 inch TV has picture and sound when I turn it on but when I change channels, the picture disappears and I have only sound. The picture comes back if you turn the TV off and back on but...


Hello, it sounds like your inverter board is goin out on the set, when you change channels if you notice on almost any TV the screen goes dark and the new channel appears, it sounds like you are not getting enough power out of the inverter board to power up the backlight enough to come on. This is why the sound remains because everything else works fine and the sound is connected to the main board.

Sound stays on & picture goes to blank screen


I do not see any reference on this problem and I even checked with Sony. If you are on a cable box, I suspect that is the problem.

Television stays on one channel


You likely have bad solder connections in the tuner.

Picture problem when changing channels


Are you using a cable box or a satelitte reciever? If so i would suspect them first. If not, unplug the TV for 2 minutes and try again.

Channnel keeps flicking like your changing channels with remote


when you say flickering??? are you saying the screen goes black and comes back on?? does the sound go out at the same time and comes bag on with the pic ? Is the sound there when this happens but is distorted. Is the pic blacked out or is it greying out with lines and twisting?? Need more info please as if its blacking out and the sound goes with it it may be going into shutdown. If the pic is getting kinda greyish with it twisting and the sound is there and ditorted then the tuner could be bad
