I have this issue, my teac ag d7900 which itself off to standby and when I switch it "on" again, it says protect and shut itself down again


Right. This means that either you have a short in your speaker cable somewhere or the short-detector circuitry inside has problems. Disconnect all speaker cables and turn the receiver on. If the symptom goes away, turn the receiver off again and connect one of the speaker wires. Repeat until it starts to go into protect again. When it does, the last speaker you hooked up has a short somewhere in the wire.
If protect always comes on, you'll need to get the unit serviced.

After a short while watching TV, I get a poping sound and my receiver goes into protection mode


Hi,

An indication of "Protection Mode" is usually indicative of a systems error. The popping sound on the otherhand is made by a hardware failure, normally a capacitor or a transistor or IC cracking up. These are of course generalized response.

Should you need more specific information, pls post back brand and model of your unit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

My teac ag-790a 'protect' error message on display. When I brought it to the audio shop for repair it worked fine; at home again the same problem? What is the problem? Tx.


Hello
Check the putput wirings to speakers. If any of them has short circuit, the set will go to protection mode. You can understand it well, as it did worked fine at the repair shope. The set has no fault at all, but the wirings, connects to it have.
Just power ON the set at your home, without connection any output or input to it. See, it will not show any protection mode display. Switch it OFF. Connect the output to speakers, one at a time, and switch ON the set. Just do it for all other speakers. This way, you can find out, which speaker line causes the set to go to protection mode. Fine out the reason.
Never connect any input to the system, until works fine with out showing any protection display.
I helped you somewhat fine, I assumes.
Ok.

Protect mode


The most common cause of this is that one of the speaker voice coils is shorted or the wiring to one of the speakers is shorted. Disconnect the speakers one at a time and see if the amp goes out of protect, if no change you have a shorted output circuit in the main amp section.

As soon as the speakers are turned on, there is a popping noise through the speakers then the receiver shuts off and stand bye light blinks


Sounds as if you may have a bad speaker component that is causing the unit to go into a protection mode to protect the unit from shorted speakers/outputs. Try to unplug the speakers entirely and then turn on the unit...If it still does this and goes into standby with the speakers disconnected then there is a problem probably in the audio amplifier circuit that will need servicing by a technician. If the unit stays on..then I would try to put different speakers on the unit to see if it works..if so, then suspect your speakers...if not , then suspect the receiver

you have speaker wires that are shorting out. unhook all the wires and ohm them out. Find out which one is shorting. I've had this problem before. It's fine until you turn it up, Then the receiver turns off and goes into protect mode. It's just a short in the wiring,.

most of the receivers come with a cooling fan inside see if its working they usually work when you turn the volume up,, if its working that means you are playing it to loud if you lower the volume a little it will play just fine..( if the fan inside is not working thats the reason it goes into protect mode and it means you must have it repaired,, it goes into protect mode to prevent furter damage to the unit or the speakers,,

Protect appears on display on kenwood kdc 3034


Disconnect all the speaker wires at the receiver and turn it back on. If itdoesn't go into protect mode, your receiver is ok.

Reconnect the speakers one at a time being sure to turn the receiver off each time you connect a speaker and turn the receiver on until your receiver goes into protection mode again.

When it goes into protect mode again, the last speaker you connected has a problem. Trace the speaker's wire to the speaker looking for cuts or shorts along the way.

If you have a multimeter, switch itto ohms and check the speaker for a dead short, if you show a dead short you have a blownspeaker. Hope this helps.

Stuck on standby


Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know kstahl65@att.net
