Ignore the fact the DMD is plugged out and the flicker from the LEDs, this is just the refresh rate of the camera [emoji1787]
I’ve a weird sound issue with my LW3
Some sounds are missing or play loud static or screeching like they are corrupt, then just randomly the music will stop.
I don’t want to buy a new sound board and find out it’s not the sound board at all.
I’ve tried:
Ribbon cable
Volume pot
PIAs on MPU
Voltages are OK, I’ve powered it up from an ATX power supply to rule out anything like ac ripple/etc.
Changed RAM in both MPU and on sound board. Changed CPU on sound board.
Verified all ROMs.
Recapped Sound board
Reset factory settings
The boot up bong or back in action doesn’t play at all, c&c music is corrupt but zztop and other one are OK
Is there a way to identify which rom is responsible for each sound?
