SPACE BALLZ TROUBLESHOOTING GUIDE
CAUSE
1) Check to make sure that the 120 volt to 220 volt converter is plugged in
and turned ON. Check to make sure you are receiving 120 volts to the
converter and that it is producing 220 volts.
2) Check to make sure that the volume knob on the subwoofer is turned up.
Keep this knob turned all the way up and adjust the volume within the
software. Also check to make sure that the bass knob is set to the desired
level.
3) Check to make sure that the volume is properly in the game software.
There are volume options for both the game mode and attraction mode. We
recommend you keep both setting at 10 for louder environments.
4) Check both speaker connections on the subwoofer and check the channel
connectors on the subwoofer.
5) Check both the speaker connection and the channel connectors on the CH-
TKQ.PCB board located between the control center and the main cabinet. If
you moved the control center at some point - it is possible for the speaker
connection to become loose. On units # 0007 - 0029, the speaker
connections were located at CN09.
6) Check to make sure both speakers in the acrylic marquee are plugged into
the correct speaker wires coming from the game.
7) Check to make sure the two pin speaker cables are plugged in between
Section # 3 and Section # 4. It is possible to have missed these connectors
during initial installation.
8) Check both two pin speaker connectors coming out of the bottom of
Section # 3 and plugging into the speaker connectors near the CPU.
9) Check to make sure that the audio cable is plugged securely into the
speaker port of the CPU.
10) If your wireless keyboard and mouse was left plugged in - it could be
possible that someone accidently muted all sounds in Windows directly.
Push the escape button on the keypad. From the Windows screen, click on
"START" and then on "CONTROL PANEL". From there click on "SOUNDS".
Ensure that the mute button is NOT checked. You may also see a shortcut to
this on the lower tray or you may be able to push the mute button directly
on the wireless keyboard itself.
11) If you have tried all of the above and still do not receive sound - plug in a
standard set of headphones into the CP audio jack and test the sound
through Windows. If you HEAR sound - then the CPU is good and the
speakers or sub are defective. If you DO NOT hear sound - the CPU should be
replaced.
