Megatouch™ MAXX™ games
PROBLEM(S)
CORRECTIVE ACTION
• no power
• bill acceptor motor does
not run
• no flash on the monitor
screen
• no cooling fans
operating
• no output from power
supply
• Check that the power cord is connected to a “live” outlet.
• Check that the power switch is on.
• Check that the power cord is connected to the game power supply.
• Check that the power supply’s voltage select switch is set to the proper voltage.
• Check the harness connections to the on/off switch and circuit breaker.
• Check the circuit breaker for an “open”.
• Check the A/C harness connection to the power supply.
• Check the line cord.
• no video
• no cooling fan operation
• screen is blank
• A/C power to the
monitor and bill
acceptor
• no output from power
supply
Unicorn motherboards
• Turn the game off and locate J3 along the edge of the motherboard next to the
audio board. There is a jumper shorting pins 20 and 21 together that will set the
motherboard to work with an ATX power supply. Move the jumper to pins 19
and 20 and turn the game on. If the fans in the cabinet start working and the
screen displays “CMOS CHECKSUM ERROR”, turn off the game and connect
a keyboard with a PS/2 connector to the motherboard, then follow the CMOS
configuration procedure for a Unicorn motherboard. After the motherboard is
configured, replace the jumper on pins 20 and 21 of J3. If the fans do not start
working and there is no display, replace the power supply.
Mitsubishi, Itox, and Telco motherboards
• Replace the power supply.
• no video
• cooling fans are working
• sound is functioning
• A/C power to the
monitor and bill
acceptor
• power supply has +5
and +12 volt outputs
• Check the video cable connections from the motherboard to the monitor or
LCD display.
• Make sure the RAM DIMM is properly seated.
• Check the fuse on the monitor
• If there is sound, the monitor may be defective.
• no video
• constant beeping or a
sequence of beeps
• The DIMM may not be seated properly or may need to be replaced.
• no video
• no sound when coins
are deposited
• Check all connections to the motherboard.
• Reseat the DIMM.
• Replace the motherboard or send it for repair.
• poor picture quality
• Adjust Brightness, Contrast, Horizontal, and Vertical controls with monitor
controls located in the CPU section of the game.
• no sound or distorted
sound
Mitsubishi and ITOX motherboards with the mini I/O board
• Check the audio cable connections at PL101 of the motherboard and J11 on
the I/O board.
• Check the speaker harness connection at J9 of the I/O board.
• Do a two-button memory clear.
Unicorn motherboard
• Reseat the audio board connected to CN7 on the motherboard. Make sure
there are no exposed header pins on CN7 with the audio board connected.
• Check the connection at J11 of the I/O board.
• Check the speaker harness connection at J9 of the I/O board.
• Do a two-button memory clear.
Telco 586 and Mitsubishi motherboards with I/O Light
• Check the speaker harness connection at J9 of the I/O board.
• Do a two-button memory clear.

PROBLEM
CORRECTIVE ACTION
• coin jam
• Check the coin mech and coin chute for coins blocking the pathway.
• Make sure the coin harness is connected between the normally open and
common terminals on the coin switch.
• Disconnect the bill acceptor and the coin switch one at a time to narrow down
the problem.
• Check the coin harness for pinched or damaged wires.
• Disconnect the coin harness from J3 of the I/O board. If the coin jam still
appears, the motherboard will have to be sent for repair.
(NOTE: Full MAXX™, Slim MAXX™ and Select MAXX™ cabinets have an
optical coin switch.)
• meter not advancing
• Check connection at I/O board.
• Check
wiring
at
J3 METER connector on I/O board.
• game locks up while
being played or in the
attract mode
• no movement on the
screen
• power has to be cycled
off and on to get the
game to function again
• Check the output voltages from the power supply:

• Clean the vents and the fans of any dust and dirt that may interfere with airflow.
• Clean the CPU cooling fan under the I/O board.
• Replace the CPU cooling fan if it is not operating properly.
• Clean the contacts between the I/O board, riser board, and motherboard.
• Reseat the DIMM on the motherboard.
• Clear memory with the following procedure:
• Power off the game.
• Press and hold the “Setup” and “Calibrate” buttons.
• Turn the game on and keep holding the buttons until the screen displays
“TWO BUTTON CLEAR DETECTED RELEASE BUTTONS”. This should
take about 30 seconds.
• Release the buttons. This will clear high scores, clear the books and reset
options, and reset the game menu and coin menu to their factory settings.
• Perform a checksum test on the hard drive:
• Power off the game.
• Turn on DS2, position 8.
• Turn on the game. The test will take about 25 minutes.
• A failed test will lock up and display “CHECKSUM ERROR” on the screen.
• A passed test will display “CHECKSUM OK” then continue to the attract
screens mode.
• game resets while being
played or in the attract
screens
• Follow same steps as above.

PROBLEM
CORRECTIVE ACTION
• game locks up with
“invalid key for version
PG3002 – V XXXX”
• Check the program number on the security key, it should be compatible with
the program on the hard drive. (Note: See the hard drive and security key
program number list.)
• Check the contacts on the security key socket. Lift up on the contact on the
bottom of the socket, and make sure there is a good connection to the base of
the security key.
• Clean the connections between the I/O, riser, and motherboards. Loose or dirty
contacts can cause an “invalid key”.
• Try another key with the same program number or test the security key in
another game with the same program version.
• “invalid key” message
while downloading
software to the hard
drive
This message indicates the motherboard did not boot from the CD ROM drive.
• Check that the CD ROM drive is set as master.
• Check the ribbon cable connections between the CD ROM drive and the
motherboard.
• Try another CD ROM drive.
• Make sure the security key is replaced after the download is completed
• Follow same steps as above.
• “OPERATING SYSTEM
NOT FOUND”
(Mitsubishi
motherboard) or “DISK
BOOT FAILURE”
(Unicorn or Telco 586
motherboard)
This message indicates the motherboard is not receiving data from the hard drive
and has locked up.
• Check the IDE ribbon cable connections at the power supply and hard drive.
• Check the power to the hard drive. It should have +5 volts, +12 Volts, and
ground.
• Check the CMOS settings on the motherboard.
• Move the hard drive IDE cable to the secondary IDE port on the motherboard
to test the board. If the game does not lock up, there is a motherboard failure
and the board should be sent for repair. The game will work this way, but it
cannot be updated with new software.
• “QUANTUM FIREBALL,
SMART FAILURE
DETECTED, BACK UP
HARD DRIVE”
• The self-diagnostics on the hard drive has detected an error. The hard drive will
have to be replaced.
• “ERROR READING
DRIVE C”
This message can be caused by the hard drive or in some program versions, a coin
jam while the game is turned on.
• Turn the game off.
• Locate DS 2, position 8 and turn it on.
• Turn on power to the cabinet. This will start the hard drive checksum test,
which should take about 20 minutes to complete.
• When the hard drive passes the test it will display a “CHECKSUM GOOD”
message
continue to boot up into the game attract screens. This indicates
a coin jam.
• When the hard drive fails the test, the game will lock up with a
“CHECKSUM ERROR” message, which will stay on the screen until the
power is turned off. In this case, the hard drive will have to be replaced.
• “CRITICAL ERROR
ABORT RETRY FAIL” –
or “BAD COMMAND OR
FILE NAME” error
• Try reloading the program onto the hard drive with a set of update CD’s
compatible with the security key. If it will not take the download, replace the
hard drive.
• “TOUCH CONTROLLER
NOT FOUND” error
• Make sure the touchscreen controller is connected to the touchscreen, the
motherboard, and the power supply.
• Perform a CMOS configuration.
• game doesn’t recognize
CD-ROM drive
• Make sure the jumper setting on the back of the CD-ROM drive is set to
MASTER (MA).
• Check if the CD-ROM drive is defective by trying another drive.
• Perform a CMOS configuration.
