Samsung LN52A550, bad screen? startup problem

[XtraTN]

Heres a samsung ln52a550 that I might buy with this problem.
The owner states "It takes 15 minutes to warmup and then it works perfectly"

Heres a photo of what it looks like when firsted turned on. After it warmups the picture looks perfect.

I know its pretty rare but could it be a bad caps issue? I remember there were some samsungs where bad caps actually caused the screen to go weird? If not, i'm guessing most likely bad tcon?

Samsung have a lot of problems with main boards, but it could be a t-con problem too... it's very difficult to call.

If the sound is unsupportable, then it's the mainboard.

If the sound is unsupportable, then it's the mainboard.

Not always...

For example, the user could have turned "TV Speaker" off, which I believe also mutes the headphones.
Or, it could be on a source without direct sound (i.e. VGA.)
Or, the wrong source could be selected.

Assuming it is the main board when there is no sound has bitten me in the past.
