Samsung LN52A550 T-Con Bad?

[stevo440]

This is my first post. Photo should be worth at least ten thousand words. Inspected, cleaned lvds cable and T-Con ribbons, looked for bad caps. Carefully massaged all around the edge of panel but no change. At this point I am suspecting T-Con board but wanted advice before ordering. Thanks in advance for your help. Complete model #LN52A550 P3FXZA

Looks like a shot panel to me, and is that oil in water looking anomaly in the photo on the left of the screen, what is that?

Scene on the screen is Scrat the squirrel (on left) from dvd "Ice Age". While playing around with set while dvd was playing, the blue band went away for 10-15 minutes but came back. Set works perfectly except for blue band.

Does it goes away if you flex the panel?

Lol I see, looks like LCD bleed. Well atleast it's not that!

Yes I did intentionally flex the panel and it did eliminate the band for a few minutes but I could not get it to do it again.

That may be tab bonding problem.

Yes it appears to be the tabs. Just taking the screws out of the metal frame makes the problem go away. I just found the "hot" tab right adjacent to the blue area at top of screen. Now I need to order the stuff to fix it. Thanks again!
