I've fixed a few of these over time but I don't see anything physically weong with this pcb. I tried a known working hard drive, both leds light up and I get the audio bong but this shows up on the screen. Anyone want to lend a hand to me in repairing this pcb please.
Thanks
Chris

Dead. Had 4 people try to fix it

Do you have any names of people who can fix KI boards trying to find out what's going on with my sound. it's just a constant buzzing noise. I don't know what to do to test mine. the cpu board test came back fine the disk test came back ok, i don't know how to test the sound roms, i'm just lost all the way around and I don't want to sell the board because it took forever for me to find. I know my midway adapter and negatron work on my blast becausei tested a MK2 pcb and sound board to make sure and it was fine.
 
Is your KI making any other sounds other than the "Buzzing" noise?

You can PM me and I will try to help you out.

thanks,
