    After playing a CD that was scratched pretty badly in my CD player, the display flashed the word, "PROTECT." Now the none of the settings work and it does not play any music or any sound what-so-ever. I've tried shutting off the car and I've tried other CD's...and it still will not work. Even the radio doesn't work. It just continues to flash "PROTECT" at me.

"PROTECT" means that the unit's thermal protection units were activated, which in turn cut off output power to the speakers. The causes for this vary. Usually, it's a problem with the impedance load that the speakers present to the power amplifier inside the receiver. Occasionally, the circuit acts up and activates itself, or playing the unit too loudly has blown a fuse. First, check all the user servicable fuses. You'll find their location and amperage rating in the user's manual. If they're broken, replace them. Make sure that none of the bare wire from any speaker is touching any bare wire from any other speaker. If the unit still won't power up, then I'm afraid you'll have to take it into the shop for evaluation by a qualified repair technician. Best of Luck.

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.

Its on protect mode and i cant get it off

Look on the face plate for a really small hole. Put the tip of a pen in the hole and hold it for a few seconds. Your system should then re-set. If the Protect signal keeps coming on, take it to the dealer to make sure your stereo is wired properly....hope this helps

"PROTECT" is displayed on the car stereo when turned on

This is really easy to fix. Look on the face plate for a REALLY small hole. Put the tip of a pen in the hole and it should work. This usually means the stereo isn't wired properly so if the PROTECT keeps coming on after you've re-set it, take it to a dealer. To make sure you're everything is in properly. Hope this helps...

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!

Security

"Protect" isn't for security on a Kenwood; it's caused by a problem with the speaker output. There may be a defect in the CD player, or you may have a blown speaker or a shorted speaker wire in the vehicle. Try disconnecting all the speakers and see if the unit still shows "protect" when you turn it on. If it still shows the "protect" message with no speakers connected, the unit needs to be serviced; if not, re-connect the speakers one at a time until you find out which one is causing the problem.

My stereo is flashing the work "PROTECT" across the front

In a Kenwood deck, "PROTECT" usually means that one of the speaker output wires is shorted. The first thing to do is pull the deck and inspect the wiring at the back, making sure there aren't any pinched or exposed wires. If a speaker wire is pinched against the deck chassis, or bare wire is touching dash metal, it can cause your problem. If you don't see anything obvious, disconnect all speaker wires from the deck, then turn it on. If it still flashes "protect", then you have a defect in the unit. If not, then re-connect the speakers one at a time until you find the one that causes it to go into Protect mode. Usually if you don't find a pinched or shorted wire behind the radio, the problem can be found at the speaker itself. This is especially common if you've installed after-market speakers; if a speaker terminal connection has come loose and is now touching the speaker basket or mounting surface, it will shut down the deck.
