Onkyo TX-SV828THX Protect message

Hooked up some speakers after not using for a while and when I turn unit on after a few seconds the display reads PROTECT. I did find a speaker wire that shorted, corrected, unplugged and replugged everything hoping to reset, but same condition. I only see 3 fuses in the box and they look fine. The users manual says to contact service center, but given the age of the box and can't find a local place to work on, hoping someone can help me here. It's a great unit, but I don't want to spend a lot given the age and just using at this stage to drive some in house speakers.

My onkyo tx-rz810 keeps going toDet.pretction mode how do I get it out of that mode


Does the display show you are in protect mode , or is a light indicating that? The unit automatically switches to standby when the
"Hardware" - "Power Management" - "Auto Standby"
setting in the Setup menu functions are set. The protective circuit function may have been activated.
If this has occurred, "AMP Diag Mode" appears on the
display when the unit is turned on again, and the unit
enters diagnostic mode. If the results of the diagnosis is
that there is no problem, the "AMP Diag Mode" display
disappears and you can use the unit normally again. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Make sure bare speaker
wires are not touching each other or the back panel of
the unit, then turn the unit on again. If "NG" is displayed,
immediately unplug the power cord from the wall outlet
and contact your dealer.
• The protective circuit function may have been activated
because the temperature of the unit rose abnormally.
If this happens, then the power will continue to turn off
after you have turned the unit on again. Make sure the
unit has plenty of space for ventilation around it, wait for
the unit to cool down sufficiently, and then try turning it
on again. This is out of your users manual.

General suggestions are to remove all speakers and speaker wiring with unit off. Turn on and see if problem has stopped. If not, let unit cool down if warm and try again later. If problem is still there it needs repair shop work. I fht problem went away, shut off power and connect one speaker at a time and testing. Keep adding speakers one at a time with power off and see if a bad speaker or wire set can be located

Hi,,My onkyo tx-sv828thx problem was it shows "protect" sometimes.then after 2 to 3 second its back to normal operation. What do you think the problem?can i do it by myself? anyway,i am using...


The protect message appears when the current powering an amplifier inside the receiver goes beyond the safety limit or the amplifiers overheat. So just check the wiring and the speakers impedance with an ohmmeter - each should be above 6 ohms
If they are lower then you have a short in one of the actual drivers of the Bose 901 speaker . If the impedance is OK then the Onkyo overheats, place it in a better position to increase the airflow thru it.

Hi, after i turn the power on and then press the stand-by button, it clicks off to stand-by mode instantly. This is an Onkyo TX-SR500


This indicates that the system is going into protect mode. First disconnect all speaker wires (with the power cable disconnected). Then turn the unit on and see if it sill shuts aff ofter a few seconds. If it does not, then you have a problem with the speakers or speaker wires. inspect the wires at both ends for frayed strands that may touch. If that all lookd good, plu the speakers in, one at a time, until the problem reappears. Be sure to turn the sytem off before plugging in any speaker just to prevent any accidental short which could be catastrophic. If the system goes into protect mode with all speakers disconnected, you probably have a shorted output transistor.

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

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.

Onkyo TX-SV434 "Protect" light


The protect mode is a built in safety message, indicating that theres a fault somewhere with-in the unit, and it wont let the unit come on fully or more damage will occour. This unit is a solid state device, and you should not attempt to use it or open it or try any self repair as it will cause more damage. If this unit is more then a few years old , it might just be the time to start looking around at all the back to school sales on electronics, as to have this unit serviced will cost an estimate fee as well as parts and labor. If you want to invest a few bucks into this machince , then go for it, but its most likly will cost 1/2 or more then the cost of the entire unit did when it was new to have it repaired. It is up to you. Good Luck
