5. Pull the Power Supply PCB apart from the rest of the unit and
disconnect the ribbon cable connector from the Power Supply PCB,
remo ing it completely.

the new PCB and back plate assembly. If the setscrews are difficult to
adjust, a 1/16” Allen wrench can be inserted into its head to rotate and
adjust the height. Make sure the setscrew height is such that the nuts
make a sufficient number of turns, but the nuts must be allowed to
tighten completely and make contact with the lockwashers.
