I have a blitz 2000 good that has no sound. I boot it up and get video that is perfect but never get any sound. Not even the start up. I get the flashing sound led. The middle one flashes while loading and the led next to it will sometimes flash. Not to sure what is going on. I installed the new hard drive flash kit recently because the board would not even boot IMG_4864.jpeg
 
you have dipswitches set to the long self test when you turn the game on? if the rom didn't work the hardware shouldn't show good. you can try taking the rom out and see if you get a bunch of red errors for the sound hardware. regardless I think you should still hear the amp pop when you turn the game on.
 
I took my working nba jam board and hooked it up to see if I had sound and the speakers played sound just fine. Something on the board I guess
 
yeah now that I think about it there's a delay in the pop and bong sound lol

I would check the sound rom. if you need rom file to compare against it's sound102.u95 in the MAME set blitz2k.zip
