-
Tip: It can be easier if you rest the speaker against the floor and make it turn.
-
Turn the side wavy rings counterwise.
-
-
-
Once you remove the ring, we can access the screws that are underneath that hold the handle to the main body.
-
-
-
Cautiously, pull the plastic rings out towards away from the speaker body, until it releases from the side.
-
Once they are loose, they can be pulled upwards and released from the body.
-
-
-
-
On the bottom, introduce a slim opening pick (screwdriver, knife, etc.) in the line of union that exist between the two halves of the cloth cover.
-
Lift the cloth cover from the rear half to reveal the screws (2 on each side).
-
Remove these screws.
-
-
-
Once you get the screw that holds the cloth cover, we open it as we open a book.
-
Tip: It looks like it is going to break but it is not like that, it works as a spring and it can be opened without problem.
-
-
-
Loosen the screws that hold the sides with the tweeter speakers.
-
-
-
Carefully lift the side pieces that contain the tweeter speakers.
-
Unplug the connectors from the board.
-
Tip: The connectors may be sealed with glue. Pull carefully. I recommend to break the glue first before removing the connector.
-
Note: I recommend to separate the tweeters when you remove them, as they have cables with different lengths.
-
-
-
Once you remove the tweeters, we can remove the sub-woofers. To do this we loosen the 8 screws that holds each sub-woofer.
-
Note: I recommend to separate them, as they have cables with different lengths.
-
-
-
After the previous steps, we have access to the main board.
-
I do not have more pictures, but once the board is out, you can also access the battery screws and the buttons, top board, and the rear plugs.
-
Note: The Bluetooth antenna is adhered to the case with double-sided tape. I recommend to separate it first before extracting the board.
-
PS: Sorry for not having pictures of the process.

I'd like to repair the volume knob on a Xiron boombox. Seems to be a loose contact of sorts. Any help available?
you need to open the device and use a tester for check the button works well.
you would need an isolated wire in order to simulate the volume button to see wheter the problem is button fisically or maybe something deeper
