Try disconnecting the Speaker that fell, and then turn the unit on. If the protect signal goes away, There is probably a problem with the speaker and it will have to be repaired/replaced.

I have Kenwood kdc- mp343 it displays protect then what happens?


Disconnect all speakers from unit. Turn on. If still in protect then unit is damaged and needs repair. If not then reconnect 1 speaker at a time until it goes into protect. That speaker is either shorted or wiring is shorted.

No sound , display shows digital protect


The most common problem found on FixYa for Audio Video2_bing.gif Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

PROTECT DISPLAYED ON RECEIVER


This generally means you've got a short somewhere, and the received is trying to protect itself.

My suggestion is to disconnect all of your speakers at both ends, and reconnect them.

Most times this happens because a speaker wire is lose, and the positive and negative connections are touching each other, causing it to short out.

Getting a "Protect" message in the display which then shuts down


The speaker wires were al little frayed, so I cut and stripped new 3/8" leads and when re-inserted the receiver worked fine. The problem was a short from the frayed wires touching either the back of the receiver or some other metal near the terminal.

Reciever turning off.


You have a short in the speaker wiring. Simply put, the pos and neg (red/black ends) of your speaker wire are most likely touching somewhere. The receiver has a short protection circuit that keeps you from blowing the receiver or your speakers. Either try re-cutting the ends of the speaker wire, or if that doesn't remedy the issue, buy new speaker wire.
