When it's first turned on, all sounds are present for the first couple balls...then the it's like life support is yanked and the pitch and volume die down to silence. Unplugging and re-plugging in the power molex connector (upper right corner of sound board) brings the sound back very briefly, but once the machine is warmed up - the sounds don't return.
Replaced the 40-pin connector between the driver and CPU (there were some visibly bad connections...slight acid damage from batteries long ago removed). Even replaced 4 elec. caps on the sound board.
I have the complete schematics.
