DISASSEMBLY PROCEDURES
Re-assembly Note: Be sure to re-install the
air baffle to avoid chassis overheating after
repair.
7. Front Bezel Removal
7.1 Perform procedure 6.
7.2 Remove the AC Switch button from the
front panel by pulling it straight off.
7.3 Remove the two screws that secure the
AC power switch to the back of the front
bezel. Lift it straight off.
7.4 Remove the four screws that secure the
front bezel to the front panel. Lift off the
plastic front bezel.
8. Fan Assembly Removal
8.1 Perform procedure 1.
8.2 Disconnect the fan wiring harness from
the SMPS PCB at J204 or J205.
8.3 Remove the four screws that secure
the fan assembly to the chassis. Lift the fan
assembly out of the chassis.
9. SMPS PCB Removal
9.1 Perform procedure 1.
9.2 Gently remove the air baffle from
the SMPS PCB where it is glued to the
capacitors. Re-assembly Note: You will
need to re-install the air baffle and secure
it in place using RTV or similar. Failure to
re-install the air baffle will result in chassis
overheating.
9.3 Disconnect the AC wiring harness at
J203. Disconnect the amplifier PCB wiring
harness at J202. Disconnect the DSP wiring
harness at J201. Disconnect the fan wiring
harnesses at J204 and J205.
9.4 Remove the six screws that secure
the SMPS PCB to the chassis. Lift out the
SMPS PCB assembly.
10. Amplifier PCB Removal
10.1 On the bottom of the chassis, remove
the two screws that secure the amplifier
PCB’s heatsink to the chassis.
10.2 Perform procedure 1 to remove the top
cover.
10.3 Gently remove the two air baffles from
the Amplifier PCB heatsink.
Re-assembly Note: You will need to
re-install the air baffles and secure them
in place using RTV or similar after repair.
Failure to do so will result in chassis over-
heating.
10.4 Disconnect the wiring harnesses at
J300 and J400. Disconnect the ribbon cables
at J100 and J101.
10.5 Remove the four screws that secure
the Amplifier PCB to the chassis. Lift out the
Amplifier PCB assembly.
Re-assembly Note: Be sure to re-install the
two screws that secure the amplifier PCB to
the chassis. It is used to help dissipate heat.
11. DSP PCB Removal
11.1 Perform procedure 1.
11.2 Disconnect the wiring harnesses at
J400 and J401.
11.3.1 PS602 - Disconnect the ribbon cables
at J403, J405, J406 and J408.
11.3.2 PS604 - Disconnect the ribbon cables
at J403, J404, J405, J406, J407 and J408.
11.4 Remove the four screws that secure
the DSP PCB to the chassis. Lift out the
DSP PCB.
