Troubleshooting guides

Fixes for common problems with popular models, in the order the manufacturer suggests.

We don't repair products ourselves, so these guides don't add tricks of our own. Each one collects the steps a manufacturer gives in its support pages and manuals, puts them in order from easiest to most involved, and links every step to the page it came from, with the date we checked it. Where our owner-complaint research covers the model, we add what owners report about that problem.

If a step doesn't match your model, follow your own manual, and contact the manufacturer before opening anything that isn't meant to be opened.
