NFL Blitz 3.0/NBA Showtime: first kinda working arcade- NEED HELP!
« on: May 25, 2017, 11:36:45 pm »
I bought a NFL Blitz 3.0/NBA Showtime 4 player cab last week. I was told that the hard drive was the only issue. So I bought a new PCB solid compact card with the IDE adapter with the ROM U27 & U37. I got the machine to turn on today. But I have a few issues.Any help, I read a bunch of forums and I am just as lost.

#1 I have no sound
it has some errors during the boot screen.
Sound Port Status: BAD
Sound Static RAM: Unknown Error
Sound DRAM: Unknown Error
Sound Tone Status: BAD


#2 None of the player  joysticks (all four of them) work but the buttons work.

Thou shalt check voltages.
