Hi - first time poster, long time lurker. I have a problem with my XBR4 that I hope someone can give me some direction on.
Background info:
I've owned a Sony XBR4 for a little under 2 years now it's performed flawlessly - that is until recently. About month or two ago, it began exhibiting similar issue as described in these two threads:

avsforum.com/avs-vb/showpost.php?p=16203884&postcount=11077
(i woudl make these actual links, but becuse this is my first post, the system won;t let me post URLS
)
Problem 1
Basically the left half of the screen looks darkened with a reddish tint, and the pixels in the dark area seem to refresh really-really slowly, creating an ultra smearing effect.
(See attached photo)
At first when this problem began, it could quickly be fixed by simply holding on to the upper left and right corners of the TV and lightly flexing the bezel. This would cause the picture to come back and would only need to be done maybe once a day.
Now - the TV is not longer responding this is and the picture is permanently darkened on the left side.
Problem 2
the second issue is that (obviously) it's out of warranty, so I need to get it fixed. I've had a tech out to look at it, and all he could tell me (after looking at for less than 5 minutes) is that he needed to take it back to his shop and then he could tell me how much and how long it would take to fix it. I decided to not send it with the tech, since, according to him, the fix would likely be a new panel. The cost of replacing the Panel is not worth fixing
Solutions???
Well, I'm going to just get a new TV later today (we needed a slightly larger one anyway
), but I want to try and salvage this one myself - if possible. I just need a little direction. After ready a tone of stuff on these boards, I think my best bet might be to just replace each of boards one at a time in hopes the issue lies within of o these.
My questions are:
1 - Should I even attempt this, or would it be an exercise in fruition?
2 - if you thinks it's possible it is one of the boards, in which order I should start?
The second photo attached is the TV with the back housing pulled off and the various boards are listed A-B-C-D-E-F-G
I know what some of the boards are, but some I don't:
A- DF2
B - GF1
C - ??
D - DF3
E - ??
F - ??
G - ??
Any help would be greatly appreciated.
