You have an amp failure, this can be a problem with a speaker but is more often a shorted output channel.

You can check to see if it is a speaker by disconnecting the speakers and then turn it on. If it goes into protect again, you have a shorted output channel. If it turns on, you may have a bad speaker.

If it turns on, try connecting one speaker at a time until it goes back into protect. When it goes into protect, you just found your bad speaker (last one connected).

Make sure you turn it off before connecting a speaker. Then turn it back on again. Do this for every speaker you have.

If it stays in protect, you should take it in for service. Unless you have the proper tools and experience working on electronics there is nothing you can do to repair this yourself. I have seen many people try who were not qualified to work on electronics, and more often than not, they cause more damage than they started with which results in a more costly repair.

Let me know if you need any more help.

This indicates a short in one of the speakers, or possibly the speakers are not wired correctly. Please see my tip at http://www.fixya.com/support/r9389300-stereo_says_protect_or_clicks_off_when .

My kenwood krf-v5300d overloaded? Stand by light flashes if pressed stops flashing if pressed again unit turns on but doesent pass start up and shuts off again havent managed to find a solution from bassic...


This unit is in what is called "protect" mode/ See the link below for an explanation of this. Specifically to your unit, the output components are unique to Kenwood and are not cheap. Further investigation to locate the reason for the protect mode will be necessary prior to any attempt to estimate the cost of repair. Something as simple as a missign voltage can cause this symptom.

Please feel free to update this with any other questions or concerns that you may have.

KENWOOD DECK FLASHING (PROTECT)


protect mode means some speaker wires somewhere in the car are grounded out or are crossed... find the short and it will fix the problem. try testing all of the speakers one by one from the wiring harness... you'll find the problem. Good luck.

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.

when the speaker wirer has a short circuit or touches the chases of the vehicle activates the protect function. so you need to get it serviced or do it your selves.Read the manual. http://www.kenwoodusa.com/UserFiles/File/UnitedStates/Consumer/Manuals/kdv415u.pdf

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!
