Modifying the Switch PCB (required when replacing the old-style PSU)
When fitted with the new-type PSU, the 861 requires a modification to the Switch board. This involves removing
a capacitor and fitting a three-pin "watchdog" IC. The Switch board is located within the front-fascia assembly.
To gain access to it, the fascia must be removed as described in Section 6.
Remove the fascia by removing the four screws
securing the front-panel assembly to the chassis.
Carefully tilt the front-panel forward and disconnect
the display loom from the Display board.
Place the front-panel assembly face down onto a
protective surface.
