Take Apart Chassis Harness Assembly - 36
Speaker Assembly
First remove the EMI
shields.
Caution:
The speaker wire
connections on the chassis
cable bridge are very
fragile. Avoid removing or
replacing the speaker wires
unless you need to replace
the chassis or have isolated
the problem to the speaker
wires. (That is, replace and
test the speakers, front
panel control board, and
analog board first.)
