WARNING!! This procedure is intended to be performed only by specially trained Melco service
technicians and personnel. Disassembly by untrained individuals will void any warranty protec-
tion and can result in personal injury or damage to the machine.
•
WARNING!! Do not attempt to disassemble the power supply unit for any reason. There are no
user serviceable components inside. Internal components in the power supply unit might still
have residual voltage (even if power is disconnected) that can cause painful electrical shock.

cable from the back of the machine.

CAUTION!! Be careful not to drop metallic hardware or tools onto the Main PCB while it is
exposed. Doing so can result in severe damage to the electronics that might be expensive to
repair.

in the front and fully remove the securing plate screw in the rear.
