Working on a Black Hole with new Pascal PI-80
The speech/sound board is original.
Speech Sound Board PS is original.
I have all sounds working except the background sound. It cut out & won’t come back.
Switch 5 for background sound is turned on.
Any thoughts?
I checked continuity between the edge connectors from the Speech board to the driver (A6-J1 to A3-J1)
Continuity is fine for Sounds, 1,2,4 & 8.
But the manual does not indicate what sounds those are.
Thoughts?
