Prior to performing the following procedure, remove
the metal cover, the main board, the rear panel and
the tuner board.

Disconnect the wire from connector CN403 on the
power amplifier board 2.

As the wire extending from the fan, take it off the notch
h in the lower part of the power amplifier board 2.

Disconnect connector CN101 and CN103 on the
power amplifier board 1, and CN402 and CN405 on
the power amplifier board 2 from the power board
respectively. The heat sink is still attached to the
power amplifier board 1 and the power amplifier
board 2.

Remove the two screws J attaching the IC bracket
(1) on the back of the heat sink, and remove the
power amplifier 1.

Remove the three screws K attaching the IC bracket
(2) on the back of the heat sink, and remove the
power amplifier 2.
