Green Picture with 40H80?

My picture is green almost all the time? Start off back in Aug 06, it was seconds at a time, then mins, then hours? Any idea what part(s) could need replacement-- is it easy to myself or should I call a repair man? Tx

Re: Green Picture with 40H80?

This is a CRT type projection TV set. You could have a bad green picture tube, a bad connection on one or more of the picture tube sockets and or driver boards, or there is a RGB driver problem in the video jungle IC or the output driver transistors. If you have had any experience with solid state TV repair, there should be no problem figuring out whats not or is working in this set. If you have not had any experience, there is alot of high voltage on these picture tube sockets, and one wrong move and you will get a perm of a lifetime. That voltage hits you so hard, I have seen it make a grown man cry. Play it safe and call in a pro to assist you in this repair. Good Luck PS Please do not forget to rate this thread.

No Picture/No Sound

This is very possibly a power surge, can you tell me how many times the light blinks, you probably have a bad power board now if you had a power surge.

Sony Grand Wega KDF-60XS955 Picture comes on and then goes off.

You have a bad lamp. Sometimes when the lamp gets old, it doesn't fail and open like they usually do. Instead, the reflector gets cloudy, and instead of reflecting the light, it converts it into heat. As the lamp heats up, it draws more power, eventually to the point where the TV senses it drawing too much power and shuts down, going into a reset cycle. replace the lamp and use an original Sony lamp, as the aftermarket lamps are known trouble makers. Be sure to rate this solution. Thanks!

Sound, No Picture

The only thing you can do is to unplug the tv for 30 min. Then turn it back on and see if that fixed it. If not call a repair man, you are most likely missing a power supply voltage or deflection voltage.
