Receiver Not Working

This should take around 30 minutes and can be done by anyone with basic receiver knowledge.

1. Check the power. This could seem like a no-brainer, but you would be surprised at how often this is the reason why electronics won't work. Make sure that all plugs are firmly seated in their respective sockets; sometimes a plug can slip out halfway and not draw power. Double-check that wall switches operating any outlets are flipped on (it's usually a good idea to connect equipment to outlets not toggled by a switch whenever possible). Confirm that all units (including any power strips or surge protectors) in the system are able to turn on. If something won't power up, test it with another outlet or socket that you know functions properly. If that also doesn't work, the equipment in question may require repair or replacement.
2. Check the speaker/source selection. Many receivers have a Speaker A and Speaker B switch to toggle connected/extra speakers. Make sure that the right one(s) are enabled and check that the correct source has been selected, too. It's easily overlooked, but all it takes is an accidental bump or press of a finger on a remote to mix things up.
3. Check the speaker wires. Inspect and test each of the wires leading from the receiver/amplifier to the speakers, paying close attention to damage and/or loose connections. Inspect the bare ends to ensure that enough insulation has been stripped off. Confirm that the speaker wire connectors have been properly installed and are inserted far enough to make good, steady contact with the speaker terminals
