    I have a 60" Sony Wega that the picture and sound turn themself off every 60 seconds. The TV repair people told me to check the lamp, but it seems to be OK, what else could be the problem ? It is a rear projection, model # KDF-E60A20.

Power supplies give a lot of trouble (besides the tube). there are two regulators that go bad very often. they may also take out the horizontal output. there are some capcitors, resistors, 2 thyristors (i believe 2) and diodes that are suggested to be replaced along with the two regulators. all of those parts are fairly cheap so it shouldn't be that big of a deal to repair (granted that is the problem and the only problem).

Sony trinitron kv32v26 remote


Check the resolution of your TV, if its too high, or the PS3 is outputting a resolution too high, it will display a black screen, I had this issue at first, but I can't recall how I reset the res, start off by checking the TV's resolution and that the Video cable from the PS3 is connected properly and that the TV is showing the correct input.

I switched the tv on and it gave me a green screen , the sound is ok


There are several reasons for displaying a green screen to Sony LCD TVs. If the main digital board's video digital processing section has got damaged, a green screen will be displayed and audio output will be OK. If panel faulty the result will be the same as above. Check this link. It has details and screen shots to various faults to Sony LCDs. Check it and determine, whether you can repair this fault by yourself.

Sony KDL-42V4100 has sound but no video. Input works but black screen and sound is ok


Hi there

this is not meant as a solution, but a tip if you`d like to get an answer.
You should clarify in which occasion you get either sound and no video or black screen with sound.
This is a little confusing for a repairman.

My Sony Trinitron 36'' model#: kv32v26 is taking a long time to show picture when turned on. The sound comes on and the red light blinks for about 3-5 min. before the picture turns on. And when i switch to...


Hi Matt.
I`ve been repairing sony tv`s for a long time now and i can tell you that what you described is sure signs of a weak picture tube.
And the price of a new picture tube makes it prohibitive to replace it. You could open the set and adjust the screen control on the high voltage transformer but it won`t last long. If you decide to do that , look for a transformer with a long and thick red wire that connects to the back of the picture tube , That is the flyback transformer and there will be two controls on it, you want to adjust the bottom control that is the screen control(the upper one is the focus).
Turn your tv on and slowly turn the screen control up until the picture shows up at a reasonable brightness level, if yout turn it to high or you may get retrace lines in the picture.
That may strech the life of your set for a couple of months .
Hope this will help. Merry Christmas
