Flashing PROTECT I was listening to my radio and it quit working. Instead it now is flashing "PROTECT" I can hit standby and it goes off. If I hit standby again, PROTECT

You need a radio code, contact this link and pay a small fee: Car radio codes in Uxbridge London Gumtree

If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.

When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.

Please see my tip at http://www.fixya.com/support/r9389300-stereo_says_protect_or_clicks_off_when . These are genericinstructions. If you get stuck or need specific instructions for your speaker model and setup.

First observe the radio device for pause buttons also known as protect that may have been accidentally enabled. Simple press button nknobs to unprotect the achieve broadcasts once more. Also, refer to the owners user manuals or guide for features.

reset button on front of radio. push in with a pin while car is on.

don't know what kind of radio you have, but usually if a radio is flashing protect it is because you have a short in the wiring, a bad speaker or a bad output ic.

wires are ok but speakers may not be which can put it into protect.other then that your head unit has an issue

i have similar. All gone off and red light flashing. Did you get yours sorted?

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.
