TOUCHMASTER ® CONVERSION CHAPTER Troubleshooting NOTICE : The conversion kit CPU Board Assembly is not interchangeable with the standard Touchmaster ® CPU Board Assembly. The assemblies look very similar but have different part numbers. The incorrect assembly will cause sync and touchscreen calibration errors. This Video Game Machine (VGM) uses complex electronic components that are sensitive to static electricity. The following precautions must be observed and followed prior to handling VGM electronics. 1. Turn off AC power to the VGM and ensure the cord is unplugged prior to servicing the VGM. 2. Discharge any static electricity build up in your body by touching any unpainted metal on the VGM, such as the chain lug. This is to be done before touching or handling the assemblies. 3. Handle the electronic assemblies by their edges and store them in an anti-static area when not in active use. Anti-static bags are to be used to store or transport the CPU Board Assembly. 4. Do not install, remove, or connect any electronic assemblies when the cabinet AC power is ON. Doing so will damage the electronic assemblies and void the warranty. 5. Always replace ground wires, shields, safety covers, etc. when maintenance or service is completed. Ensure that all ground and mounting screws are installed and tightened firmly. 123 545 4
Troubleshooting - 2 Midway Amusement Games, LLC VGM Does Not Start Symptom Problem Suggested Solution • VGM appears non- functional. • No audio • No fan • No video display. Lack of electricity Check that the Power Switch is set to ON and VGM is plugged in. • VGM appears non- functional • Fan works. Poor AC connection 1. Check the air flow out of the cabinet by the fan. (This does not mean that voltages or signals are as they should be, but it does indicate that there is DC power available from the Power Supply.) 2. Turn off power. 3. Remove line cord cable clamp. 4. Test line cord, power plug and I.E.C. connector for breaks or damage. 5. Verify the continuity of each wire in cord. 6. Fully seat I.E.C. connector into the mating cabinet receptacle. 7. Replace cable clamp and all of its screws. 8. Ensure that cabinet wiring harness connectors are fully seated in the corresponding AC Power W iring Harness connectors. 9. Verify the AC wire connections at the Power Supply terminals. Tripped circuit 1. Examine the AC Circuit Breaker on the cabinet. 2. If the circuit has been broken, the reset button will be protruding from the Circuit Breaker. 3. Press the button in until it latches to restore power. Faulty AC line filter 1. Examine the AC line filter on the cabinet. 2. If the filter is faulty, replace it with an identical filter of the proper voltage and current rating. 3. Connect the line cord and verify operation. 4. Fully seat the AC plug in the outlet. 5. Verify that AC line voltage is present. 6. Turn VGM power ON. 7. Check the DC wiring harness and connectors if the breaker opens the circuit again. • VGM appears non- functional • Fan operates. Poor DC connections 1. Unlock and open the cabinet rear cover while AC power is on. 2. Inspect the CPU Board Assembly under low light level conditions. 3. You should see a glow from the LEDs 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
Touchmaster® Conversion Kit Troubleshooting - 3 receiving some DC power from the Power Supply.) 4. Turn OFF VGM power. 5. Unplug the AC line cord. 6. Inspect the CPU Board Assembly. 7. Ensure that the DC Power connector is attached and fully seated onto the mating board connector. 8. Check the other wiring harness connectors in the same way. WARNING: DISCONNECT POWER. Do not remove or install any connector when power is turned on. Doing so will damage the CPU board assembly and void the warranty.

Faulty video fuse 1. Examine AC line fuse on Video Monitor Board.
2. If fuse is faulty, replace with identical fuse of proper
voltage and current rating.
3. Connect line cord and verify operation.
Poor voltage Plug in VGM and turn ON power.
Using the 20 Volt DC range on a digital voltmeter,
measure DC voltages at the CPU Power connector
pins.
Refer to the Typical Cabinet W iring Diagram for specific
wiring information and voltage limits.
Adjust the +5V source if it is variable.
Using the 2 Volt AC range on a digital voltmeter,
measure the same DC voltages as above. Any reading
here indicates that the supply voltages are unstable and
may contain ripple or noise.
Verify that the VGM runs and completes the power-up
self-test sequence without any errors.
Note errors and/or failures found during these tests.
Remove cash door.
Enter Menu System by pressing the SETUP button
inside the coin vault. From SYSTEM SETUP menu,
choose the VIDEO TESTS (refer to Section One for
additional details). Use these tests to check the
operation of screens used in the VGM.
