Title:

Has anyone disassembled and repaired one

Text:

Hello all
 
I picked one of these music centre devices up (LG CM9730) think it was released around 2013.
 
Now at the rear of the device is the speaker outputs for both speakers both LEFT & RIGHT. With four connections for each speaker.
 
With a HIGH & LOW connection points. Anyone who owns one or any similar high powered LG stereo system will know what I mean.
 
Basically I want to repair and replace two of the speaker outputs, as the terminal posts and screw caps have been broken off, probably due to over tightening at some point.

I need to get access and clearance to the main PCB board, as the speaker outputs are soldered onto the main board.
 
Possibly the speaker outputs are Banana Type connectors that may be bolted onto a chassis of some kind.

I believe one part number for the BLUE (Left Channel) is EAG63410801
 
However I’m unsure of the part number for the RED (Right Channel).
 
 
 
Now then, has anyone ever taken one of these machines apart before ?
 
If so I’d like to know the best way to do it. I have removed all visible screws that hold the side plates on. But the thing won’t come apart.
 
I found the service manual for the item, but doesn’t explain the best and safe way to take it apart.

Any ideas from anyone would be appreciated.
 
Thanks for reading.
