Hi everyone!
I recently bought a used JBL Quantum 910 Wireless headset.
The microphone mute button was physically stuck inside the headset, so I decided to disassemble the left earcup to fix it.
I managed to open the headset and access the internal circuit board. The good news is that both the microphone mute and ANC buttons work correctly when the board is outside its mounting position.
However, I'm having a really hard time putting the board back into its original position.
When I reassemble everything, the buttons become misaligned and stop working properly.
The headset itself works perfectly fine, including the audio and microphone. The only issue is the physical alignment of the ANC and mute buttons.
I've spent several hours trying to fix this, but I couldn't find any service manual, teardown guide, or video showing how to properly reinstall this board.
Has anyone disassembled a JBL Quantum 910 before?
I'm specifically looking for:
- Pictures showing the correct position of the internal button circuit board.
- Instructions on how to align the ANC and microphone mute buttons.
- A service manual or reassembly video for this headset.
I've attached pictures of the internal components.
Any help would be greatly appreciated. I really don't want to damage this headset while trying to fix two buttons.
Thanks!
