Question about Onkyo TX-SV454 Receiver
This means that you have a problem with the speaker outputs.
-Try turning the unit off and unplugging it.
-Disconnect all of your speakers.
-Plug it back in and turn it on.
If it works, check you speakers and wiring for shorts.
If it still shows protect then you probably have a blow output amplifier and it will need repair.
