The audio amplification PCB is the PCB which has the task of amplifying the B212D speaker's input signals.

단계 1 Audio Amplification PCB  ¶ 

Remove the 2 indicated flat head machine screws indicated using a #2 phillips head screwdriver. The small PCB could be removed for replacement at this point, but you can also just leave it attached to the audio amplification PCB as you remove other parts.

단계 3  ¶ 

Note the 4 large flat head machine screws which hold the clamps on the opposite side; remove them with a #2 phillips head screwdriver. The clamps are meant to hold the audio amplification PCB's IC's to the common heat sink; they ensure proper contact between the heat sink and the IC's through the ceramic thermal paste.

Note the 3 flat head machine screws holding the heat sink to the metal electronics box; remove them using a #2 phillips head screwdriver. It may be possible to leave this heat sink connected, but you will have to separate the heat sink from the IC's and be careful not to touch the ceramic thermal paste: its really hard to remove, even with soap!
