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

A-SV640 KEEP GOING TO PROTECT MODE


Hi, try powering up the unit with out any speaker connected if it still goes to PROTECT try factory reset if possible.
To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter standby mode.
If this does not fix your problem you should take your unit to service . :)

DENON UD-M30 CD Player is displaying the word PROTECT and will not function. Any ideas how to fix this problem? Many thanks.


HI:
Usually when a receiver goes into protect mode, there are several reasons, One is there is a bad speaker connected to the unit, this will cause the unit to to into protect mode, try disconnecting all speaker from the unit and turning it on if it does not go into protect then one of the speakers are bad. Another reason is the power output Amplifier IC is shorted inside the unit. Another reasons could be that speaker wires are touching each other and causing a short. Disconnect all unit connecting to the unit and try turning on, if it stays on and no protect then connect them including the speakers one at time until you determine which is causing the error. If it goes into protect with nothing but the unit on then the Output IC is bad and the unit needs servicing.

Protect mode. will it work again? how can "i" fix


This indicates a load on the system, turn receiver off, remove speaker wires from the back of the unit. Now power up and turn volume right down, if the word protect stays off, there is a short in the wires or one of the speakers. But if the word protect comes on, "with wires and speakers dis-connected, it means there is a short in one or more of the audio outputs in the receiver. If you are handy using a digital meter then you may be able to track the shorts down, and replace the parts to get it up and running, also if you can solder then it will make the job easier.

My stereo says" protect" everytime i turn it on. can't get anything else.


Hello grammagrisbo, hi your Kenwood head units will show "protect" when there's a problem with the speaker outputs so check to see if the impedance load meets your radio, 8ohms or 4 ohms?. having parallel two speakers on a single channel may cause this dilemma. This might also mean a shorted speaker wire, a blown speaker, or an internal defect in the head unit. Once the condition that's causing the "protect" mode is fixed, the CD player should be back to normal, the next time you turn it on.
If it's staying in "protect", then you'll definitely have to remove the stereo and do something to fix it. Many car audio stores will do system troubleshooting, for a fee. If you want to do it yourself, here's what you need to do:

Pull the Kenwood unit from the dash and disconnect all the speaker wires. power it on and see if the "protect" message displays. If it does, the stereo has an internal defect and will need to be serviced. If it doesn't, then turn it off, and re-connect one speaker only. Turn it on again and see if it will displays "protect" message.

If the radio works with one speaker connected, connect the other speaker to the second channel, you may have now the idea where the problem begun, you will identify the speaker that's causing the problem. There may be a wiring problem or defective speaker in that channel.

If it displays "protect" with a single speaker connected, then disconnect that one and try the other one. If all the speakers cause a "protect" mode, then you're probably back to a defective head unit.

My 450 watt fusion amp is now in ''protect mode''. how can i fix this?


Start by completely turning off the power to it and anything connected to it. Turn all levels down to there lowest volume settings. Check to be sure your speakers are not shorted. Be sure the power voltage is correct. Turn on each of the items, the amp being last. That probably will resolve the problem but I am not that familiar with the unit just trying to help. Most units have stay in protect mode until I cycle the power. Typically they monitor the speaker current hence a short would cause almost an instant protect fault.
Good Luck,

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

If your problem is "switch on then after 10secounds shuts down and protect appears on the display .and cannot do anything with it but turn it off"

Then the unit is on protect mode, that is a special diagnostic mode that starts when the unit detects an internal fault.

To start unplug the unit from power for ten minutes, and see if this reset the protect mode, I guess you have done this already.

The first thing to do is to start the unit with nothing connected, if the unit does not go to protection, then the problem was one of the cables or a connected device.

If that does not fix it , there is a master reset , by pluggin the unit into main while at the same time you hold the power button.

If still no luck then the unit is defective and must be taken apart and tested with a multimeter.

You start checking for burnt areas on circuits, cold solder joints and leaking capacitors at sight, then there is need to grab the multimeter and do the real testing job.
When you find the problem you do the soldering.

Naturally this requires a certain experience in fixing electronics, to complete the job usually a precision soldering is needed.
