Facing TV Problems? Ask a TV Technician.
Hi. I'm Steve. I'm sorry to hear about your TV. I will try my best to give you a precise and accurate answer.
Is there a chance you could find me the full model number of the TV? It will be on the back somewhere.
Ok. The audio circuits are on the main board which is part number SC0-P519201GMI4
Good luck finding one as I have been unsuccessful.
They occasionally show up on sites like www.shopjimmy.com for about $150.
The board is easy to change out.
Just ask if you need more help on this issue. I will be here.

On this TV, one board has all the circuitry except for the power supply circuits.
It is an extremely complex board using surface mount technology, repair is seldom an option.
It's the main board. It needs to be replaced - it cannot be repaired. The audio circuit has failed. It cannot be isolated an repaired.
The Main board is pretty easy to ID. There are only two boards in the TV, the power supply and the main board.
Yes, the whole back comes off. You will see two large boards (10"x10" approx) The power supply is a beige/brown board with a couple of heatsinks and the power cord going to it. The Main is the large green board that has the external connections mounted to it.
You can't miss it.
