Introduction
If your TECHUP Bluetooth speaker, Model No. AR456, has recently lost functionality, it is likely the motherboard is at fault. This guide will take you through how to replace that motherboard step-by-step. This process will involve disconnecting the internal battery, and although this device runs on low-power, there is a shock hazard anytime you are working with open wires from a battery. Take care when soldering/desoldering the battery wires.
If you do not know how to solder, you may use [guide|750|this guide].
