Onkyo SR705 receiver standby flashes (Amp protection?)

I found the source of my hum. I have Direct TV HD. I found that going into the menu settings (Direct tv HD Receiver) /Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver!

The problem is not with the inputs. This unit is in protect because a problem has been detected in the output section. Try disconnecting the speaker wires and turning it on. If the unit remains on, there is a short in one of the speaker wires. If the unit still shuts down, there is an internal problem that will require repair. It sounds like this is a new piece. If so, it should be covered under warranty.

Keep us posted,

if what Dark_Orbit said does not work try doing a master reset by ressing and holding the dvr/vcr button and stand by button simultaneously. This would erase all your assignments so you would need to reassign all your sources hooked up to your onkyo.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Hello Fixya customer,

Thank you for your question.

The best way to fully isolate the fault is to disconnect all the speaker wires, and verify that there are no strands of wire shorting between the speaker terminals on the rear of the unit.

Turn the volume all the way down, full CCW, and if it goes into shut down with the STBY light blinking then there is a fault in one of the amplifier's.

Thank you for using Fixya, and if I can be of further assistance please ask.
