My cat peed on my Onxyo TX 8011 receiver. Now when I turn it on it goes into PROTECTION MODE. Something I can fix myself (remove the cover and clean the circuit board) Is it fried? Worth fixing?

Onkyo tx-8011 started to go into protected mode, I thought it might have been dust buildup within the knobs of the Volume,treble, etc. cleaned no joy on that assumption. so now I am back to ?

Hello, I am sorry about your issue. The receiver may have detected a problem with a speaker or speaker wire. Please remove all of the speakers and unplug the receiver for at least an hour. Plug back in and turn on without the speakers connected. If it stays on turn up the volume to maximum and leave on for ten minutes. If it stays on lower the volume and add one speaker. Turn on and leave on for several minutes. Continue this procedure until all speakers are connected. If it does not stay on after the one hour it would need to be serviced. Thank you, Onkyo USA

Why no sound on Onkyo TX-8011

Hello Randy Risher, At this point being that you are not getting any audio from any source, I would suggest a reset. To do this press and hold down the Tape 1 input on the receiver. While holding that button down press the Direct Tuning button. You will see the word CLEAR in the screen which indicates that you have done the reset correctly. If after the reset the audio does not return then the unit would have to go in for service. However, being that it is very old (2004 model) it's not guaranteed that there are parts available for the receiver. I would call our product support team at 800-229-1687 x3 to see if your receiver is eligible for trade in program. Thanks, FJD

My Onkyo tx-ds595 reciever turns on but after 5 seconds it goes into protect mode. I really would like to fix this porblem myself. Please help.

This can be caused by shorted speakers or speaker wiring, disconnect all the speakers and see if the problem goes away.

Onkyo tx-8211 protect

It's unlikely you can. Most hifi shops can though.

If you're still reading, open it up, and look for a switch of some kind. It may not even exist, but I'd say it's the best thing to look for when doing something considered mediocre at hifi shops (if it was difficult and interesting, they wouldn't find it so boring). Maybe it's a button. It will probably be labelled protection or reset or something similar.

So, look for a switch, or something similar. I have no idea where it would be because I've never dismantled such a thing. The other option (if you haven't done so already) is unplug it from the power and leave it for a while (overnight may be the best bet). This may fix it for you, and it's easier than undoing all those screws.

No sound coming out of speakers something is wrong with the receiver

check if it goes to protection mode on power on. see to it that speaker selector switch is set.

Is your speakers connected properly?

Is your music source ok?

Do you hear a click after you switch on the power? the click indicates that the time-on delay transfers the amps output to the speakers which prevents thumps going out to the speakers.

Once it goes to protection mode you need to have it serviced. This is due to a fault in one of the amps and that it protect the speakers from further damage.

Display indicates "Protection" and unit shuts down. What causes this and how can I correct? Will a shorted speaker cause this?

Yes, there are two ways to check this, either disconnect all the speakers at the speakers or do the same at the receiver. I would start at the receiver, this is the most common problem of all AV users. Disconnect all speakers (with the receiver off) then turn it on. If it does not go into protection it is either a wire or a speaker, the best way to troubleshoot this is to reconnect each speaker one by one making sure you don't have any excess braid hanging over the pins then turn on the receiver. repeat until the unit goes into protection or, you've solved the problem. If you find a speaker with a problem, if possible replace the speaker with a known working speaker and test again. If it still goes into protection, run a new speaker wire and test again. At this point if it is still going into protection, you may need to get it to a repair house or AV store, have them bench test the unit for you first, then if needed, send it out for repair. If you need any help at all during this, post a comment and I will help some more.

My 605 turns off and red light blinks when volume goes past 58

Shorted speakers can cause the unit going on protection mode (the red light blinking) when a certain volume is reached.

Test with a set of replacement speakers.

If it is not the speakers, it is probably transistors in the amp final or something nearby. Test also input output board.

Onkyo TX-DS777 goes straight to protection mode

Hello.You have shorted audio outputs. One of your channels has shorted output transistors. If your unit uses output ICs then one of them is shorted. Both types ( individual transistors or ICs ) are located on the large finned heat sink. The parts are available from http:\\ good luck
