    I have unplugged everything as well as the AC and left it off for an hour. I tried the factory reset (hold the VCR button and press Standby). Is there a fuse inside the unit I could replace?

Hmm there could be just a fault with this amp if it is brand new.. other wise you might have shorten some wires to geather by accident, try taking out all the audio leads accept the power and see what happends..

if the lite doesn't come on then turn the power off and plug one thing in at a time and turn the power on each time you plug something in..

hope it helps good luck

I got an Onkyo amp- TX-SR674, don't know why i turn on it but after 2 seconds, it will switch off and standby light is flashing, can many times. Please help


If the stand by red light starts blinking after 4 seconds of switching On it indicates an output short circuit. In all probability one of the Amplifiers output stage is defective and to prevent speaker damage the protection circuit is getting activated in 4 seconds. You will need professional help to fix this.

Onkyo & Harmon Kardon it a very nice unit and it built very professionaly and very sensitve unit. Its very important that you make sure the correct pole is connect correctly when it come to speakers. the unit come with resetable breakers inside the receiver (safety protection) so you wont blow or short the unit if not connected up correctly. when wiring speakers up from an to the receiver you have to make sure the poles are hook up correctly. positve speaker wire go straight to positive plug behind the receiver same as negative. the speaker wires should have some kind of making on it to mark as either positive or negative. try that and see if that help, if nedd more help.

Power will not stay on


Activated protection circuitry means that the amplifier is seeing conditions it does not like and is shutting down the power to prevent further damage.
Either you have a short in your speaker wires, in your speakers, or a blown amplifier.
Disconnect both speakers and turn on the amplifier. Does it still give the error message? If it does, your amp is blown. If it does not, carefully inspect your speaker wires and their connection. Make sure all looks good and reconnect the speakers and try it again. Still get the error message? You likely have a problem in your speaker cabinet(s).

1-disconnect subwoofer first and test-and then disconnect surround speakers-and front speaker after-and later center speaker.ever time you disconnect you check the operation until you find the bad one(or two)which make the problem change its cable first and then change speaker itself.if all above failed contact the service center.

Power up problem


try powering the unit right down by disconnecting from the mains supply. fire up after 5 mins and see what happens. There is a separate transfomer for the standby supply(small red light) An internal fuse may have failed or the thermal fuse inside the transformer. If fuses blow as sson as you fire up = output transistors hay be short circuit.

Onkyo receiver problems


All speakers and lines OK?  Sorry for basic approach!!  Protection is supposed to work when speaker outputs are loaded under recommended Z. speaker Z is a setting too ... along with several other paramenters.  Also, re the "last return" ...  Maybe the back surround speakers were turned off in settings?  Again, apologies if you've tried all this basic stuff.  I've just bought one of these amps and have probs with the FM tuner not tuning anything.  Mmmm. Back to the shop??   Cheers, Chris

Amp Protection Mode


no, your output transistors maybe 2 of them are gone or the small power supply that feeds the other circuitry has become defective.
