Hoping on some help because im stuck. Working on a Williams Millionaire and got speech an sounds but no backgroundmusic.
CPU D-11883-567 (U1 not populated)
Checked voltages OK
Soundboard swap to my earthshaker and got sound and speech. So problem must be on the CPU board.
Soundtest (SW1) on the CPU gives me speech (millionaire) and one sound, after reading a lot this should also be oke.
Ribboncable between soundboard and CPU, checked oke.
Game boots up and in to attract mode, everything is functional.
The only thing i can think of is that the CPU should be populated at U1 or am i wrong here?
Any help where to look would greatly be appreciated.
Thank you all for your answers.
Kind regards kevin.
