My home theater shut off and when turned on show message "Check SP Wires". What to do?
Yamaha's trouble shooting method for early shut off applies here.
"1, disconnect all of the speaker wires from the back of the receiver.
2, turn the receiver on, and turn the volume control up to about half way. If the receiver stays on, please go to Step 3. If the receiver shuts off right away, the unit will require service. Please consult with your dealer for further assistance.
3, carefully inspect all of the speaker wiring and the connections at the back of each speaker. Remove and reconnect the wiring at the back of each speaker if necessary.
4, re-connect the main speakers only, and test the system. If operation appears normal, turn the power off and re-connect the surround speakers. If it shuts down prematurely, you should have your main speaker system checked.
5, test the system after the surround speakers have been re-connected. If operation appears normal, turn off the power and re-connect the center speaker. If it shuts down prematurely, you should have your surround speakers checked.
6, test the system after the center channel speaker has been re-connected. If operation is normal, you have located and fixed the over-current condition.
If the receiver shuts off prematurely, you should have the center channel speaker checked. Other problems which might cause premature shut off can include using speakers with impedance of less than 4 ohms, an internal problem with the receiver, or a problem with a source component."
