My 720 has no sound except coinup (taco bell sound), also zero control from stick, anything jumping or crashing distorts slightly.
I have tested the harness, +5 is great, reversed speaker wires to verify speakers, and have continuity through the harness. In test mode I hear sounds and speech, but is garbled at the end of words.
I have tried three different LETA chips (may all be bad).
Buttons and coinup works fine.
Any Ideas will be appreciated.
Thanks!
Update : fixed sounds by replacing chip 6116 row 1 second from last chip on CPU PCB.
Update 2: fixed control, the plugs on the optic board had been reversed. I was getting good voltage so i switched them. Wala its works!
Any Ideas on the other problem?
