You would be best off to get the service manual. Start by verifying
supply voltages, and then tracing the signal paths with a scope.

The most basic thing you can do, is to start looking for cold solder
conections. Pushing and sort of putting bending pressure on the
circuit board can help to show if there are any cold solder
connections. To work on your set, you may need the extension service
harnesses.

Considering the age and type of set, I would be seriously looking at
getting a new set.

Hello, i have this set...65xbr10w....iirc circa 2000 'vintage'.

Now, there may be an intermittent issue developing with this set....so
far only during 1080i playback...this set has one 480p/1080i capable
component input. The issue is that there has been some intermittent
'coloring' of picture....taking on a yellowish/blue cast almost as if the
red crt is 'losing some output' or 'fading out'. It has happened
relatively infrequently & seems to have corrected itself on it's own when
it does happen....so far only only one HD source has been doing this, dvd
upscaled through a PS3 to 1080i & 1080i video game through PS3. I haven't
noticed anything from HD cable TV sources..but that is not to say it
isn't there. I haven't noticed it during blu-ray disc playback either.
It has been very infrequent so far......i'm working on the assumption
this is not the PS3...but the beginnings of some sort of CRT failure on
this large, older HDTV. Thoughts?

Thx for any comments.
