Sony Bravia 52" 1080p LCD TV
Model KDL-52XBR5
Chassis: FIX2
Diagram: http://www.searspartsdirect.com/model-part/kdl52xbr5/0996/0333600/50031817/00003.html

This problem developed over several months time. At first, it was only a vertical band of pink or blue color distortion/dimming and trailing on the left 1/4 or so of the screen, and if we turned the TV off for a bit, then back on, the problem would go away. But now it's expanded to the left-hand 3/4 of the screen, and it doesn't go away. I tested the picture using different input sources, with no change.

I did open up the back and checked for leaking or bulging capacitors, etc, very carefully, and I didn't see anything. I wanted to test what I'm *guessing* is the secondary power supply on the dimmed side (there are two identical boards, one on each side, which are connected to the main power supply board). I have a multi-meter, but I'm not sure exactly how to test the board. Does the TV need to be turned on to test it? Other than that, I guess maybe I just need to know which wires to touch my probes to, and what voltages I'm looking for, if I'm even on the right track.

Photos of the TV picture (sorry about the flash, couldn't turn it off): http://imgur.com/a/FiiL9

Any help would be greatly appreciated!

This looks to be a problem with the tab bonds of the panel.
