That is the problem, we do not have the diagram of the board, otherwise you have to search lots of spec for the IC's.

You may want to read post 9 by OP so you have to watch where you get the replacement board from.
I hope that DKWILL will have the follow-up so we can ask him to check the 'LAMP STATUS' pin 13 DCV reading.

Thanks, Bud. But DKWILL's symptom is with audio. With audio means definitely main board works properly. That mean the initial stage of main board is passed and works main function but only screen problem.
My problem is different. My problem is no picture, no sound, only showing v logo and completely power and backlight off. I hear no sound after having problem.

By the way, thanks bud. I will ask him where to get the new board. I am going to buy new main board. I really hope that my problem will be solved by replacing new main board.

Merry Christmas!!!

I am refering to that when he put in the new board (defective board) it acts like your TV.

'One more piece of info. I ordered a new main board, board I got I think is defective cause with it installed, tv comes on, same as before, but after showing logo, whole tv shuts down. Power light goes off, this doesn't happen with original board, just loses back light.'
Shopjimmy is where I get my boards.

You mean, even though main board is replaced by new, the problem still remains. Therefore, it's not main board problem?

Hi. Bud. Your comments make me confused.
