Voltages are good so I replaced U101 and 102, the sound ROMs, and the BSMT2000. Still have no sound at all whatsoever. Any help fixing this problem would be greatly appreciated.

I'm hoping someone can tell me what I'm missing.

Is everyone else just as stumped as I am?

Bump! Still haven't figured this out.

Quoted from tonyhoff1:
Did you test the socket that is up top left next to the other ram chip. I had that socket go bad on me

Are you referring to U4?

I tested U4 and U7 sockets. Those are all good.

I'm reading page 110 in the manual and it says, "Sound data from the EPROMs is read through U19 to the BSMT". Could U19 be what's causing no sound? From the little research I did it appears that it would need to be programmed. Can anyone confirm this? If it does need to be programmed then how would I go about getting that done?

I swapped boards with my Elvis and the sound works! I see that these boards are really hard to find. Would a PinSound boards fix my problem?
