MY TV SCREEN IS JUST A WHITE LINE?

The actual freezing problem can be caused by the GPU overheating and SO can the no display error as well. For an in depth look at how to fix both of these problems see this > http://www.bestps3repairguides.com/

That usually indicates that the optical block is going bad. That repair is usually 900-1100 dollar fix.

PART NUMBER 915B403001 Lamp (180W)

bad thing trany going that the sign that it needs to be replace

If still under warranty, I would suggest going that way as this is a bad matrix driver....

The x-sus or y-sus panel wil be the fault.Check the fuses on these panels ,if one of the fuses is open then that panel must be replaced.Not verry cheap to replace.

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.

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider

It has a problem in the vertical sweep circuit that puts a nonlinearity in its output and you see the glitch in the normally gradual sweep as a line. Since a hit upside the set seems to help, you should just resolder the whole vertical circuit area (doesn't take long) and see if that cures it. If not, start replacing the electrolytic capacitors in that area.
Hope Ya Fix It!
