Use the flat end of a spudger to lift the power supply up off the posts in the rear housing.

Lift and remove the power supply from the rear housing.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

During reassembly ensure that the rubber grommet on the AC power harness is in the slot in the power-supply cover.

Ensure that the green ground wires are secured under the power-supply cover.
