JBL Charge 4 Motherboard Replacement

はじめに

The motherboard is responsible for making sure all of the parts in the speaker work together. It is also responsible for Bluetooth functionality and contains all the connectors for the different parts. This guide will show you how to replace the motherboard in the event that it fails and none of the parts in your speaker are functioning properly.

You have to remove the 8 mm screws before you try and Prius the other side. They are attached, and will break

Using the plastic opening tool, lift the tab on top of the speaker to release the radiator from the clips.
Repeat this process on the other clips around the radiator to release it from the frame.

There is absolutely no reason to remove the passive radiators if you want to replace the speaker only!

Just cut to step 6.

Also the difficulty level is way too high. I found it very easy to disassemble the unit.

手順5

Push the radiator off of the frame of the device.
Repeat on the other side.
The passive bass radiators seal out water from inside the device. Removing them multiple times may compromise the waterproof nature of the speaker.

Remove the sticky tape to expose the white ribbon cable ZIF connector.
Flip up the black locking flap on the ZIF connector with the tip of a spudger or your fingernail to release the cable.
Remove the white ribbon cable from the battery cover and place the cover to the side.

Don't remove this white ribbon cable from the circuit board, it's almost impossible to plug it back. Instead of removing the cable, just remove the circuit board which is glued loosely to the plate. If you can get to the battery itself, you don't have to remove the circuit board neither.
