This Sony speaker is the model SRS-XB43. This guide is to replace a faulty or malfunctioning motherboard within the system. Please refer to the Troubleshooting Page before beginning the replacement guide steps. While you go through the guide to replace the motherboard, try not to touch the exposed circuitry or components as the natural oils on your hands can transfer onto the electronics, which can possibly produce negative effects. Before starting the repair, wash your hands thoroughly and keep your fingers at the sides/edges of the motherboard.
