Introduction
If your Sony SRS-XG300 (model XG300) is producing no audio, use this guide to replace the power button.
Before using this guide, review the troubleshooting page to ensure the best solution is replacing the power button. The power button, also known as the "power switch," controls the flow of electricity to the speaker. The physical switch allows a quicker way to turn the speaker on or off without needing to unplug the speaker from a power source.
A faulty power button can result in no audio in the speaker. Power needs to reach all components involved in creating audio. A loose or broken power button disrupts the flow of electricity to all parts in a speaker. As a result, the device does not turn on and does not emit audio.
