Detach the Power Switch

A nice thing to do at this point might be to detach the power switch from the rear body panel. Then you will have a small, convenient switch to use if you want to probe voltages on the main board. Turns out this is possible, though a little difficult.

There's also some risk of cracking one or more body panels during this part. If you're concerned about that, you might prefer to rig up your own switch and just skip this section.

This part is shown on page 10 of the Assembly Diagram.

Detach Switch Panel From Rear Body Panel. Sit down and place the rear panel in your lap, concave side toward you. Use a stout screwdriver to pry the right corner of the rear body panel apart from the button panel (CAB707) as shown at right. The goal is to free the right-hand plastic tab shown on page 10 of the Assembly Diagram.

Once the right-hand tab is free, the button panel can be separated by twisting it to free the bottom hook and left-hand tab.

Detach Power-Switch PCB. Remove the phillips screw securing the PCB to CAB707. Press out the PCB unit by pushing up the edge where the retaining screw was. You will then be able to slide out the small PCB with switches and reattach its cabling to the main board at connector J1.
