Killer Instinct 2 with no sound and other erros

[Fandangos]

I have a KI2 with working HD and the game play fine except for sound.

I remember seeing similar issues like that on other threads but I haven't seen an answer on how to fix that.

Here's the error:

I have a KI1 board that works fine. Since both boards are almost identical I assume the problem is on the board itself and my supergun is hooked just fine.

Sound Processor probably died. I had a KI2 board that had the same issue. These boards run really hot. Those boards really need to have a fan blown on them while running. All the KI1+2 dedicated cabs had a computer fan mounted to blow air across the board 100% of the time.

Sound processor is that analog device SMD chip?

Is it possible to find just the chip to order?

EDIT: Forgot to say I'm getting 9 beeps when the pcb turns on.

I'm not at home. What is populated at U36?

U36 is a bad sound rom. Should be an easy fix.
