CHAPTER 6 – SERVICE
External PC Power Supply
The external PC power supply powers internal PCB cards like the u5.1AMP, illuminated buttons on the driving
control panel, ventilation fan, and all the lights on the cabinet. If you are experiencing a power problem with all
of this hardware it is likely that the power supply has gone bad. To replace the external PC power supply,
unplug the 2 power cables and 1 AC power cord connected to the power supply. Then pull the power supply
out. It is held to the cabinet with Velcro.
