Control Problems
Symptom
Probable Cause
Solution
Start Button does not work or is partly
inoperable. Or the selections keep
scrolling on Operator Mode menus.
Switches not properly connected.
Make sure that the common post of the
switch is connected to ground.
Make sure each individual switch is
working by doing the Control Panel Test
found in the SYSTEM TESTS section.
Make sure that the signal wire for that
particular switch is connected to the
normally open post of the switch.
Check if pump/trigger of gun are stuck.
JAMMA Harness connected improperly.
Identify Pin 1 on the JAMMA connector
and on the PCB. If installed incorrectly,
damage to the PCB may have occurred.
Coin counter not working
Miscellaneous.
Make sure that the signal wire has a
connection from the counter to the
board.
Make sure counter has correct voltage
supply connected. +12 or +5,
depending on the model.
Verify that the counter is good.
Power-Up Problems
Symptom
Probable Cause
Solution
No reaction when game is turned ON
Voltage too high or too low.
Defective Power Supply or wiring
problem.
Short between power and ground.
Check for foreign material.
Disconnect the harness and measure
the resistance between power and
ground. It should read around 600
ohms. (0 ohms is a dead short).
Make sure harness is not shorting to
anything, i.e. bare or frayed wires
shorting out or hitting bare metal.
No power from the power supply.
If 20-pin ATX connector is connected
properly then replace power supply.
Short on the board.
Check for loose or foreign material on
the board.
Hard drive connected improperly.
Run the power-up test by holding down
the START button during power-up.
Check all Hard Drive connections.
JAMMA Harness connected improperly.
Identify Pin 1 on the JAMMA connector
and on the PCB. If installed incorrectly,
damage to the PCB may have occurred.
Open on socketed IC’s
Check for bent pins on socketed parts.
Make sure that all IC's are seated in
their sockets properly.
Miscellaneous Problems
Symptom
Probable Cause
Solution
Green LED not blinking (D5A or D20)
Program not running.
Make sure all socketed IC’s are seated
correctly. Look for bent pins.
Run the power-up test by holding down
the START button during power-up.
Bad connections.
Make sure you have continuity from
PCB to power supply.
Sounds Bad
Miscellaneous
Check the speaker connections.
Try another main PCB to verify the
problem.
On power up game goes through a long
test ending with the Player Control Test
Start switch is stuck or the signal wire is
connected to the normally closed post.
Fix the Start switch. Put the signal wire
on the normally open post.
