(3) Replacing the MCD AMP PC Board
To avoid electric shock, accidents or injuries to yourself or other people, or damage to the
electronic circuits, be sure to turn off the power switch before starting work.
PC boards are sensitive to static electricity. If a person handles a PC board while charged with static
electricity, the parts on the PC board may be damaged. Before handling a PC board, discharge the
static electricity from your body; for example, by touching the surface of grounded metal.
Turn off the power switch of the machine. (See “8A-8-1 Turning the Power Switch On” on page 95.)
Remove the service panel L on the L side of the center assembly. (See step
of “8A-4-1 Connecting
the Front Assembly and Center Assembly” on page 68.)
Remove the regulator base. (See step
of “8B-4-1-(2) Replacing the Switching Regulator” on page
106.)
Disconnect the two connectors, remove the four cap screws (M) (M3 x 6), and remove and replace
the MCD AMP PC board.
