GAME DOES NOT START
1.
Game appears completely non-functional; no audio, no illumination, no video display.
A:
Check that the Power Switch has been turned ON (top left rear corner of the typical cabinet)
E:
Turn OFF the game power. Unplug the A.C. line cord. Unlock and remove the cabinet rear door
The Power Supply Line Voltage Switch must be set to agree with the local A.C.
lrne
voltage.
C: Remove the Line Cord Cover Plate Test the line cord, power plug and I.E.C. connector for
breaks or damage. Verify the continuity of each wrre in the cord. Fully seat the I.E.C. connector
into the
matrng
receptacle of the cabinet. Replace the cover plate and all four screws.
D:
Ensure that cabinet wiring harness connectors are fully seated in the corresponding A.C. Power
Chassis Assembly connectors (refer to Power Wiring Diagram, Section Three).
E:
Examine the A.C. Line Fuse on the A.C. Power Chassis. If the fuse is faulty, replace it with an
identical fuse from the spare parts bag. Replace the spare fuse when repairs are complete.
F: Fully seat the A.C. plug in the outlet. Verify that A.C. line voltage IS present. Turn the game
power ON. Check the D.C. wiring harness and connectors if the fuse opens the circuit again
2:
Video game appears non-functional, but currency acceptor price indicator is illuminated.
A:
Unlock and open the coin door. Inspect the CPU Board Assembly under low light level conditions.
A glow will be seen from the Light Emitting Diodes if there is voltage in the processor circuits.
This does not mean that voltages or signals are as they should be, but it does indicate that the
CPU Board is receiving some D.C. power from the Power Supply.
B:
Turn OFF the game power. Unlock, open and remove the rear door. Remove cover and inspect
the CPU Board Assembly. Ensure that the JAMMA Wire Harness connector is attached and fully
seated onto mating board connector. Check the other wiring harness connectors in the same way.
CAUTION: DO NOT REMOVE OR INSTALL ANY CONNECTOR WHEN POWER IS TURNED ON.
DOING SO WILL DAMAGE THE CPU BOARD OR HARD DISK DRIVE AND VOID THE WARRANTY.
C: Verify that the game CPU DIP Switches are set as intended. Refer to the DIP-Switch Test
(Section Two) for variables and default settings. incorrect settinos will affect other test results.
D: Turn ON the game power. Using the 20 Volt D.C. setting on a
digrtal
voltmeter, measure D.C.
voltages present at the Power connector pins Adjust the +5V source if it is necessary. Refer to
the Cabrnet Wiring Diagram (Section Three) for specific wtring information and voltage
Irmits.
E:
Using the 2 Volt A.C.
settrng
on a digital voltmeter, measure the same D.C. voltages as above.
Any reading here indicates that the supply voltages are unstable and may contain ripple or noise.
F: Verify that the game runs and comple:es the power-up self-test sequence without any errors.
Note errors and/or failures found during these tests.
G: Enter the game Menu System by pressing and holding the BEGIN TEST switch
insrde
the coin
door. Select DIAGNOSTICS from the Main menu. Once in the DIAGNOSTICS menu, choose
MONITOR SETUP (refer to Section Two for additional details). Use this set of tests to check the
operation of each screen used in the game.
