6 Repair Logs

Did you do a repair? Log it here as a possible solution for others.

PROBLEM: Center pop bumper fires randomly during game play and test mode but NOT during attract mode

SOLUTION: Issue was resolved by replacing the ceramic disk .047 mfd 50 capacitor located on the leaf switch of the pop bumper.

PROBLEM: Left Flipper is very weak

SOLUTION: Issue was resolved by replacing the flipper coil with the correct coil for starters. #AQ-25-500_34-45, Then adjusting and cleaning the End Of Stroke(EOS) leaf switch resolved the issue totally.

PROBLEM: Start button is not working

SOLUTION: Traced start button wire back to MPU board location. Found the .100 Trifurcon Terminal Pin to be mangled. Removed the .100 Trifurcon Terminal Pin from molox connector and replaced. Reinserted back into molox connector and start button now works.

PROBLEM: Certain words are garbled or missing

SOLUTION: Determine which sound ROM is causing the problem. Clean the ROM legs. If that doesn't work, replace the socket(s). If the problem still exists, one or more of the sound ROMS are bad or the data has become damaged. The original ROMs can be replaced with standard 2732 EPROMs, as long as the jumpers below the ROM being replaced have jumpers only in the "A" and "C" positions.
