Sound Troubleshooting

Audio faults follow patterns, and working through them in the right order turns a frustrating evening into a ten minute job. This section is the diagnostic shelf. It works through no sound at all, dialogue buried under effects, sound that cuts out every few minutes, subwoofers that refuse to pair, and rear speakers arriving a beat late. Each guide ranks the likely causes by how often they turn out to be the answer, and gives the specific test that confirms or clears each one before you move on. There is help for crackling and popping, mains hum from a ground loop, rattles that come from the furniture rather than the speaker, and the remote that stopped responding. You will also find when a firmware update is worth the risk, how to factory reset without losing your calibration, and the point at which a repair stops being worth paying for.
