JBL Charge 3 Motherboard Replacement

Introduction

The motherboard is the last piece of your speaker you should try replacing if it is not operating properly as it is the most difficult to access.

What you need

    • Turn your speaker upside down and insert the plastic opening tool vertically into the slit in the front cover.

    • Pull apart your cover gently from both sides and remove it from the speaker housing.

    • There are screws around the foot of the device that may need loosening to be able to unclip the other side of the cover.

    • The inside of the front cover has holes that must match with their corresponding pins on the speaker housing for proper reassembly.

    • Removing the Front Cover does not affect the waterproof seals of the device. However, removing any further disassembly of your speaker will require removing waterproof seals and gaskets. Your device may no longer be waterproof after these have been altered.
