My jvc stereo is stuck on protected and it won't change the radio station off protected


Radios that are in "protected" mode often indicate a short in a speaker wire or a really bad speaker. Disconnect all eight speaker wires: white, white/black, gray, gray/black, green, green-black, violet, and violet/black. Turn on the radio and see if it still shows "protected". If it does, the radio is defective. If not, connect each pair of speakers back one at a time and see if it goes into protected mode. The one that causes it is the bad wire/speaker.

My protection light is on and the amp goes in and out. how can i fix this problem?


Either there is a malfunction on the amplifier , or more likely there is a short on the speakers cabling. If the cables are shorted, or broken, not allowing a sufficient load, the amplifier will protect itself by tripping a fuse. After a while, or on restart, the fuse will rearm itself, only to be tripped again by the malfunction.

Turn the unit on and it plays a few minutes then it goes into protect mode.


pnOne of your speakers is grounded. Start disconnecting them one by one behind the radio after it enters protect mode and then it will turn back on.

Boat stereo shuts off when turning up the volume


When any radio shuts off wth high volume it is caused by several things.

1. The maximum power output was reached and the unit goes into the self protection mode.

2. The most common reason.... The power transistor has partially failed and will not provide the partially amplfied output necessary.

3. Units with removable face plates vibrate enough to disengage the face plate contacts so the unit shuts off.

4. The speakers are too big for the radio causing it to self protect. (system mis-match)

5. Loose connectors/pins on the radio input and output connections.

6. A poor system ground that is good enough for low volume use but when high power use is encountered the ground is not good enough to carry the amperage necessary.

These are the most comon reasons for a unit to shut off at higher volumes.

It is not always an easy fix troubleshooting this problem. I know first hand as a life long electrician that has the exact same problem with the radio in my automobile. (Mine appears to be a power transistor grounding problem) With shipping to the repair center each way and the flat rate repair cost it would cost as much as a new one!

Thanks for using FixYa.

My jvc hx-d7 radio is turned on in 2 seconds it shuts down to protect mode how do i take protect off ?


You can't. The main amplifier module will probably have a channel blown. The unit is detecting this and tripping into protect mode to stop further damage occurring. Needs to go to a repair place. sorry. ps If you get sound briefly before it trips off then it may just be a speaker wire shorting out! worth checking

Stuck in protect mode


Speakers shorted out, blew a fuse. Replace the unit or (cross your fingers and) open up the box and find the blown fuse.

"Protect" message


It is most likely an amplifier problem. I had this problem before. It went into "Protect" mode and shut down. When I turned it back on, my left channel speakers made a buzzing noise and did the same thing again. I got it diagnosed at an electronics repair shop and they found that the two STK amplifier IC's were bad. One is about $106 and the second one is about $78. I got it fixed for about $200 and works basically like new again.
