DISASSEMBLY PROCEDURES
2.3 Grasp the console between the top and
bottom of the unit, ensuring that you have a
good grip on the unit, and carefully flip the
console over onto its feet. Lift the top cover
straight off.
3. Inner Bezel Sub-assembly Removal
(includes Button PCB, IR Receiver PCB
and Display PCB)
3.1 Perform procedure 2.
3.2 Unplug the inner bezel sub-assembly
ribbon cables from J6500 and J6700 on the
main PCB.
3.3 Using a Phillips-head screwdriver,
remove the three screws that secure the
bezel to the console. There is one screw at
each end of the bezel and one in the center
below the IR receiver.
3.4 Lift off the bezel. The button PCB, IR
receiver PCB and display PCB will come off
with the bezel.
3.5 The IR receiver PCB is connected to the
button PCB by a ribbon cable. To remove it,
unplug the ribbon cable at the button PCB
end, and use a small flat-tip screwdriver to
push back the small plastic arm that retains
the PCB in the bezel. Lift out the PCB.
3.6 The button PCB is retained in the top of
the bezel. To remove it, unplug the IR re-
ceiver PCB ribbon cable and the button PCB
ribbon cable. Once the ribbon cable is
unplugged, press upward on the ribbon
cable connector on the underside of the
bezel top edge. The button PCB should slide
off of the bezel posts.
3.7 The display PCB assembly is located in
the right side of the bezel. To remove it, lay
the bezel face-down. Use a small flat-tip
screwdriver to release the display PCB from
the four retaining clips. Lift out the display
PCB assembly. Note: The display PCB
assembly is not repairable. You must replace
it as an assembly if it is defective.
