3.1.9 Removing the amplifier 1 and amplifier 2 boards
(See Fig.17 to 19) [For DX-T9]
• Remove the metal cover, tuner, fan, rear panel and main
board.
(1) (1)From the right side of the main body, remove the screw
N attaching the earth wires to the bottom chassis. (See
Fig.17.)
Reference:
After reassembling, fix the earth wires with the spacer as
before. (See Fig.17.)
(2) Disconnect the amplifier 2 board from the bridge board in
the direction of the arrow while releasing the claw j of the
connector
CN200
on the bridge board. (See Fig.17.)
(3) (3)From the left side of the main body, disconnect the card
wire from the connector
(See Fig.17.)
(4) Disconnect the amplifier 1 board from the bridge board in
the direction of the arrow while releasing the claw k of the
connector
CN201
on the bridge board. (See Fig.18.)
Note:
When releasing the claws (j, k), take care not to break
them. (See Figs.17 and 18.)
(5) Take out the amplifier 1 board and amplifier 2 board togeth-
er from the main body.
(6) Remove the two screws P and remove the leaf spring. (See
Fig.19.)
(7) Remove the two screws P and remove the amplifier 1
board from the heat sink. (See Fig.19.)
(8) Remove the four screws P and remove the amplifier 2
board from the heat sink. (See Fig.19.)

er from the main body.
(6) Remove the two screws P and remove the leaf spring. (See
Fig.19.)
(7) Remove the two screws P and remove the amplifier 1
board from the heat sink. (See Fig.19.)
(8) Remove the three screws P and remove the amplifier 2
board from the heat sink. (See Fig.19.)
