do you agree that the board needs to be replaced and is it an easy fix?
Expert:  Tim Nolan replied 4 years ago.
Yes, I would agree 95% of the time this board causes it 5% of the time the sustain board causes it. I would be replacing the buffer.

Its quite simple to swap out, just be careful that you do not damage the ribbon cables going to the panel.

on last clarification please.
Are you saying that PN BN96-12956A is the sustain board that needs replacing or is it a buffer board.

According to post I saw the y sustain board is on the left side of the set and that is the one that I reset the connectors.

Please confirm that is the board that you believe needs replacing.
That should do it for me.

Yes y sustain is on the left side.
