1. Turn the receiver off and then on again. Sometimes you just need to recycle the power to get it to go.
2. Are any other items plugged into the same outlet? If so, are they working? If not, plug something else into that outlet to confirm there is power. If you determine there is no power, replace the fuse or reset the circuit breaker.
3. Does your receiver have a replaceable fuse? Check the back for a removable cartridge. If you have one, you can likely and it is damaged, you can likely get a replacement at Home Depot.
4. If the outlet is delivering power and there is no fuse on your receiver, and it still not responsive , you will need to bring in your receiver for repair.
