Introduction
Use this guide to replace the motherboard in a Logitech UE Hyperboom Bluetooth Speaker. The motherboard sends and receives signals to and from every component in the speaker. Signs of motherboard issues are total power failure, inability to charge, connections issues, or a physical burning smell. If any or multiple of these apply, it is possible you have a motherboard issue.
Note: Although the speaker replacement guide is listed as a prerequisite, you only need to remove the speakers at the near the top panel to access the motherboard (i.e. skip steps 5 & 6).
Before beginning this guide, be sure to power off your speaker.
