I Replacing the Silver-Braided Connecting Cord On The GLA-55 Slave speaker
•
Follow steps 1-5 in the procedure below “GLA-55 disassembly Slave speaker (w/ cord)”
II GLA-55 disassembly Left, Slave speaker (w/ cord)
1) Support the loudspeaker with one half section of the packing foam with the base facing upwards.
Alternately, if the packing foam is not available, the speaker must be supported so the base faces
upwards in a clamp so it can be worked on easily, taking care to pad the clamp so the enclosure will not
be scratched.
2) Peel off the four rubber pads on the base cover.
3) Remove the (4) Phillips screws that are now exposed
4) Remove the base cover from the loudspeaker and slide the cord grommet out of the notch
5) Unplug the six pin Molex connector from the small circuit board and set the cord aside.
6) Remove the (3) Torx size T10 screws from the small circuit board
7) There are (4) connections that need to be desoldered (they appear as blobs of solder). Desolder and
remove all excess solder with braided wick or a desoldering tool.
8) Remove the small circuit board; detach and watch for the small, loose “light pipe” that you do not lose it.
9) Remove the (10) Torx size T10 or Phillips screws holding the silver main base on.
10) Remove the single Torx size T10 or Phillips screw (for port tube)
