Blown Speakers
Remove the speaker grill covers, and visually inspect 
each speaker. Run the Sound Test from the Operator 
Menu to verify each speaker is working.

A weak or low muffled sound is a sign of reversed 
speaker wires. Check for reversed wires on each 
speaker. 
Audio is Distorted or 
Muffled 
Faulty Power 
Supply 
A constant low hum in the speakers can be caused by a 
faulty power supply that contains a ripple or noise in the 
power that is being passed through to the speakers. 
Faulty Audio 
AMP 
You can verify the Audio AMP on the Jamma Conversion 
Board is working by installing it into another working 
cabinet. If that is unavailable to you, plug a simple 
computer speaker into the audio ports on the computer 
and verify that sound is working from the computer.

each speaker. Run the Sound Test from the Operator

Loose or Faulty 
Video Card 
Verify the video card is firmly plugged into the AGP slot 
on the computer. When the computer is ON, verify the 
fan on the video card is spinning and working properly. 
When the computer boots up, it performs a PC self-
diagnostic test. If there is a problem with the video 
card, you will hear three beeps from the computer. 
No Video
Loose or Faulty 
Video Cable 
Verify that the video cable is firmly connected to the 
computer 15-pin video port and the 15-pin video port 
on the Video Converter board. Check the video cable 
and make sure it is not pinched or frayed. 
Faulty Hard Drive
If you are getting no audio and no video, and the 
computer is powered on, you might have a faulty hard 
drive or corrupted software on the hard drive. Reload 
the software from the System Restore CDs to see if 
this solves the problem. If you continue to have hard 
drive problems while you reload the software, you may 
have a faulty hard drive. 
No Video, No Audio
No Power to 
Computer 
Verify the line voltage is set to the correct voltage for 
your area (115V or 230V). Disconnect the AC power 
cord from the computer and then reconnect it to power 
ON the computer.
