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

I bought a stereo from my son's friend and it has worked great for the past four months, but today I was going down a really bad street and hit a huge pot hole, then the words "PROTECT" started flashing and the radio will not work at all. What do I need to do? I appreciate your help if you can. Thank you, Shank22

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.

Simple fix: while the radio is on, take the face off and you will see a small hole in the plate the face attaches to, which usually says "reset". push a pin in the hole to reset the radio. Most of the time that will take it out of protect mode and radio will work. if it is still in protect mode, then do what tech says, test the wires.

How do i bypass the brake

Most wiring harnesses have a solid orage wire for illumination of the radio and also have an orange wire with a white stripe for dimming purposes. Most radios do not use this dimming feature. Connect the brake wire to this wire and your able to watch your movies whenever you want. All the wire is looking for is a signal. It cannot differentiate between a parking brake signal and a non-parking brake signal.

Opening on the 'Clock Set' screen
togle down to cancel and use the camera and make sure that you have the camera to flash, if it works try again in the Auto function.
If it is still not working do not worry follow the steps again two or three more times, As this is generally a software error message and not a hardware malfunction.
If it is working then don't forget to set your Clock.

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!

I had a similar problem, and took it to an authorized repair shop(under warranty), the kept it six months, and JVC finally admitted there are solder connections with that model, and six months later, we got a new unit. I will buy Sony next time
