When I turn on the TV, I get a light green picture that fades to an even darker green and then the TV shuts off. Any ideas of what could be causing it? FD Trinitron WEGA KV-34XBR800


My thoughts is that your CRT - Tube is going out.
May be time to think of replacing it.
There is what is called an electrical Gun in the back of the tube. This is what will emit the Green, Blue and Red electron beams on the front of the screen. Sounds like something has been damaged in this gun area.
Blessings,

Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
