one sound ROM in this set. The ROM is labeled 
with assembly number and software version. 
2.  Check that the cabinet wiring is correct. 
3.  Ensure all cabinet ground wires are connected. 
4.  Refer to Typical Cabinet W iring Diagram for 
specific wiring information. 
 Poor voltage  1.  Using 2 Volt AC range on a digital voltmeter, 
measure voltages at speaker terminals. Any 
reading here indicates that the supply voltages are 
unstable and may contain ripple or noise.

Video Problems 
Symptom Problem Suggested Solution 
• 
Monitor appears 
non-functional. 
• 
Audio is functional. 
• 
Controls operate 
normally. Lack of electricity  1.  Unlock and remove cabinet cover. 
2.  Verify AC Power is connected to Video Monitor. 
3.  Inspect neck of CRT under low light conditions. A 
glow near the CRT base while voltage is in filament 
circuits indicates some monitor circuits are 
receiving power. 
  Poor connection  1.  Turn off AC power. Verify that Video Signal and 
Remote Adjustment Board connectors are fully 
seated on the Video Monitor Board Assembly. 
2.  Ensure video connector pins are in the same 
orientation as the original connector. 
3.  Check other connectors in same way. Do not 
operate monitor without Remote Adjustment Board. 
  Faulty fuse  Examine AC line fuse on Monitor Board Assembly. 
Replace faulty fuse with identical one of proper voltage 
and current rating. 
  Loose parts  Ensure no loose parts or wires are caught or pinched 
by chassis or the mounting brackets. 
 Incorrect 
adjustments 1.  Check that brightness (intensity) and contrast are 
not been set to minimum levels. 
2.  Verify that Video Monitor operates correctly by 
placing in known functional unit. 
  Poor voltage  1.   Plug in line cord and turn AC power on. 
2.   Using 20 Volt DC range on a digital voltmeter, 
measure DC voltages at CPU power connector 
pins. 
3.   Refer to Typical Cabinet W iring Diagram for 
specific wiring information and voltage limits. 
4.   Adjust +5V source if it is variable. 
5.   Using 2 Volt AC range on a digital voltmeter, 
measure DC voltages as above. Any reading here 
indicates that supply voltages are unstable and may 
contain ripple or noise. 
• 
Power-up self-test is 
functional. 
• 
Game does not 
appear. 
• 
Audio is not 
functional. Error message  1.  Note and record error messages during self-test. 
2.  Turn off AC power. Restore after one minute. 
3.  Note and record new messages that appear. 
4.  Unlock and remove cash door. Enter Menu System 
by pressing the SETUP button. 
5.  From the SYSTEM SETUP menu, go to 
DIAGNOSTICS and choose VIDEO TEST . These 
tests verify some functions of the video circuits.

  W rong ROM  Verify correct ROM instruction set. There is more than 
one ROM in a set. Each ROM circuit is labeled with 
assembly number and software version. 
• 
Monitor does not 
lock onto signal and 
provide stable 
picture. 
• 
Colors missing, etc. Poor connection  Check connectors and cables for wiring continuity from 
CPU Board Assembly to Video Monitor. 
 W rong board 
assembly 1.  Ensure correct CPU Board Assembly. Some 
monitors require different sync polarity than Midway 
production units. Units with incorrect polarity or 
unusual sync connections result in what appears to 
be horizontal tearing or complete loss of sync. 
2.  Verify that Video Monitor operates correctly by 
placing in known functional unit 
• 
Machine operates 
normally. 
• 
Video wavers or 
rolls, has dark bars, 
uneven colors, etc. Poor connection  1.  Check connectors and cables for wiring continuity 
from the CPU Board Assembly to Video Monitor. 
2.  Ensure all cabinet ground wires are connected, 
especially at Video Monitor Chassis. 
  Interference  1.  Move cabinet away from appliances, other 
cabinets, etc. Some equipment normally emits very 
strong electrical or magnetic fields. 
2.  Verify Video Monitor operates correctly by placing 
in a known functional unit.

Miscellaneous Malfunctions 
Symptom Problem Suggested Solution 
• 
Machine operates 
normally. 
• 
Cabinet gets very 
warm after several 
hours of use. Poor air flow  1.  Check bottom and rear of cabinet for blocked air 
flow. 
2.  Move cabinet away from heat sources. 
3.  Turn off AC power. 
4.  Apply a high-power vacuum cleaner to fan vent 
holes to remove dust. 
 Poor cooling 
system Unlock and open rear door. Ensure all fans are 
connected and operate at full speed. 
• 
Touchscreen 
requires excessive 
recalibration to 
maintain accuracy. Touchscreen abuse  1.  Clean entire cabinet frequently, especially video 
screen glass and Touchscreen area. It is not 
necessary to switch off AC power for cleaning. 
Apply isopropyl alcohol and warm water to a clean 
cloth or sponge use it to wipe the surface. Do not 
apply cleaner directly on unit. Liquids could drip into 
circuits and cause erratic operation. 
2.  W arn players to use one finger at a time. Multiple, 
simultaneous touches confuse the controller. 
 Infrequent 
calibration Repeat Calibrate and Calibrate Test sequence each 
time cabinet is relocated. 
• 
Error messages 
appear on screen. 
• 
Machine is not 
functional. 
• 
Audio is not 
functional. Defined by 
message 1.  Check assembly (RAM, ROM, battery, 
Touchscreen, etc.) identified in error message. 
2.  If errors seem to occur at random, determine what 
conditions occur with the appearance of the 
message (i.e., time of day, when other equipment 
is turned off or on, when room temperature is 
elevated, when certain people are playing, periods 
of low or high humidity, etc.). 
3.  Call your authorized distributor for help with 
unresolved screen messages.

“Security Key Error” 
message Security failure  1.  Check if security key is missing or incorrectly 
installed on CPU Board Assembly. 
2.  Confirm that security key version matches software 
version.
