3.2.4 Sounds Deluxe

Place holder for Bally Sounds Deluxe Sound Board

This sound board has a common problem with DAC failure. AD7533 chip is easy and inexpensive to replace. You can prevent failure by removing C12 (47 uf) capacitor. It seems to have no adverse affect but prevents a voltage condition on power down that can destroy the DAC.

The LED with flash a check sequence on power up. 6 Flashes ROMS and RAM are OK.

4 Problems and Fixes

4.1 Power Driver Issues

This may not apply to some, as MPU might have been part of it.

4.4 Display Driver Board

Possibly doesn't apply to some, can't think of an example.

4.5 Coins Register But Don't Credit Up

This is commonly seen on VPinMAME emulation, but applies to real life as well.

Coins drop OK, switch is good, game makes noise, but it remains on "Credits 0" and doesn't credit up.

Symptom is corrupted/blank NVRAM.

To fix, open coin door (make sure coin door switch is working, otherwise the keypad won't work), then do these steps:

Hit "Test", to enter operator mode.

Hit "A" until "Feature Options" is displayed.

Hit Enter.

It will say "Reset Factory Is".

Hit 6, then 5, then Enter.

Hit "Game" to return to attract mode. You'll know it worked because it will take longer than usual to reach attract mode, and the display will flicker slightly as the computer clears the memory (this is normal).

Intuitive and easy to remember, right? And Bally had the nerve to advertise "manual-free testing"....
