SOURCE: Protection mode

I banged my head against the wall on this same issue and finally realized that my rear surround speakers were mixed. My rear right was wired to rear left because I was turning around to see L and R. It would shut off at about volume level 40, which was loud but not rumbling. It now ROCKS and is in no way a problem with heat. I have always run it with the cabinet open to allow air to circulate.

SOURCE: onkyo ts595 goes into protect mode with volume increase

HI check your speaker cables are not touching, also make sure "b" speakers are not on and that all your speakers are 4ohm or higher as this will cause the amp to shut down if they are to low an impedeance,The amp is protecting itself when it shuts down.

hope this helps.

SOURCE: my onkyo receiver (tx8511) keeps going to protect

Hi there
To answer your question;
Your amplifier goes into protect mode when it detects a fault or condition that could damage the speakers and/or the output stage.
Often caused by shorted outputs.
Although this does`nt tell you much on how to fix this problem, the best help i can give you at this point is to tell you to have it looked at by a repair shop.
Hope this help good luck

Every time I turn on my Onkyo receiver it goes in to protect mode.

Please check your speaker cables. Make sure that all of them are seated properly, none is touching each other or to the body of receiver.

Are you using banana plugs for connecting speaker or just directly. Some times even a little tiny frayed speaker cable touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough to activate and it could blow a few trasistors in the power output circuit.

Please take out all the speaker cables, unplug your receiver from the mains and try to restart without any cables plugged. If it powers on then you are lucky.

If not and the receiver still goes into protect mode or wont turn on then it possible that there are bad connections on the main board or have some blown transistors. How old is your system? if its still under warranty then you should contact Onkyo immidiately.

Let me know if I can be of any further help. Please do rate this solution and thanks for using FixYa!

I just hooked up my old Onkyo TX-8511 receiver to my bose speakers, which is also hooked up to a subwolfer. When I turn the volume up the system goes into protect mode. Any solutions.

Just check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Rewire if necessary..

Otherwise, do your bose speakers play out load on other systems?

Onkyo ts595 goes into protect mode with volume increase

Hold the VCR/DVR button in and press the ON/OFF Standby button. The display should briefly read CLEAR and then the unit switches off. If that clears protect mode, you'll need to redo the Audyssey and configuration setup as these will have been cleared by the reset.
