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.

  1. JBL Charge 4 Motherboard Replacement, Speaker Grill: 手順 1、 1の画像 1
    • Flip your speaker over and insert the plastic opening tool into the slit on the grille.

    • Pry away from yourself towards the back of the speaker to release the clip.

    • Repeat this process for the clip on the other side.

  2. JBL Charge 4 Motherboard Replacement: 手順 2、 2の画像 1 JBL Charge 4 Motherboard Replacement: 手順 2、 2の画像 2
    • Remove the two 8mm Phillips #0 screws from the other edge of the grille.

    • Pull apart both sides of the grille.

    • Lift the cover off of the speaker.

  4. JBL Charge 4 Motherboard Replacement, Passive Bass Radiators: 手順 4、 2の画像 1 JBL Charge 4 Motherboard Replacement, Passive Bass Radiators: 手順 4、 2の画像 2
    • 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.

    There is a major mistake in this guide, there is absolutely no reason to remove the passive radiators! The difficulty should be lowered also.

This guide has a vital flaw. Just look at the loose wire cause by a broken solder in image 16!
