So what do i do if when i turn my onkyo tx-sv454 receiver on it says protect and then shuts off? How do i fix that or get around it? please help me....

check this link for information on Onkyo receivers

No one would be able to troubleshoot it over the phone or internet. Take it to a reputable shop and get an estimate, then decide if it's worth the cost.

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.

disconnect speakers turn up to 60 and see if cuts out if it does not cut out check your speakers

Sounds like your receiver is fried. Your best choice is probably to take it to a repair facility, where they can figure out what component failed, or to buy a new receiver.

I was able to solve this problem by using the "A" speaker jacks and eventually I pushed the right buttons to get the Surround mode to turn ON. I believe it was when I hit the Parameter Selection button that allowed the surround mode to become active.

the shorted spkr wires probably fried the putput transistors in that channel.  Do you know how to use a Fluke  test meter on diode test

unsold all the power transistors,if it is power IC amplifier unsold also then turn on TX-SR701 receiver if doesn't shuts off after a minute then the problem is solve there is a defective transistors and power IC.


i hope it may help,

regards

You need to replace the internal fuse.

i believe protect mode is because you have the wrong impedence speakers, they are too low (4 ohm? 6 ohm?) it chols work with 8 ohm speakers
