Troubleshooting your Sharp receiver when it won't power up

• If you're using the remote control to attempt to power up the receiver, try using the power button on the receiver cabinet to power it up.
• If the receiver won't power up when you press the power button on, check the power cord. Plug the receiver power cord securely into the electrical wall outlet if the outlet cord plug is loose.
• If the receiver power cord is properly plugged into the electrical wall outlet, check the electrical outlet for power by plugging a different item into the wall outlet. If the wall outlet is dead, reset the house circuit breaker for the wall outlet. Have an electrician repair the wall outlet if it remains dead after resetting the house circuit breaker.
• If you have the receiver plugged into a surge protector, check for a tripped circuit breaker on the surge protector. Reset the surge protector circuit breaker if it's tripped.
• If the receiver is getting power through the power cord but won't power up, you may need to replace the power supply board in the receiver.

Troubleshooting your Sharp receiver when the speakers won't play

• Check the output settings on your receiver's control panel first. Make sure that you have the correct speaker output selected. Adjust the audio output settings if necessary.
• Check to see if you have the headphones plugged into the headphone jack. Unplug the headphones to play the speakers if you find the headphones plugged into the headphone jack.
• Check the speaker wire connections. Make sure that speaker wires are plugged fully into the speaker jacks on the back of the receiver. Make sure that the speaker wires are securely connected to the speakers. Reconnect any loose wiring connection.
• Check speaker wires for damage. Repair or replace any damaged speaker wire.
