Samsung LCD TV Display Issue

[dgambino1]

I'm hoping for some advice from the experts around here about the issue I'm experiencing.

I have a Samsung LCD LN52A650 where the LCD is showing waves. Long story short is that it was having the power on/off issue. It wasn't the capacitors in the power board and it ended up being the main board (I swapped them both out).

Can anyone offer any support on this one? Please? Here is link to gallery if pics are bad.

Can we see the picture of the T-CON board.
So cap C102 on the main board is bad?

Thanks for the reply bubm!

I will get a pic of the t-con board asap. Are my screenshots an indicator of a bad t-con?

The main board is fine now as I replaced it with another one but none of the caps seemed bad on the original board (nothing bulging/leaking). The TV is in perfect cosmetic condition. Its been babied its whole life.

yep it does. Probably the AS-15 ic on the T-con board is bad.

Hey guys. Here is a pic of the Samsung's t-con board.

How does it look?

I never mentioned it but the TV is model LN52A650A1

I think this set uses an AS19 chip
