Sounds like a cold solder! Does the amp feel super cold at room temp?
Sounds like you either shorted something out or overloaded the amp. Is there any odor coming from it? If so It will need to be repaired or replaced. What did you have connected to it and how was it wired?

You may have loosened a solder joint on one of the components inside with your air blast. A repair tech would monitor the outputs DC offset voltage and he will probably see one that is not zero volts and while wiggling various things he should see a sudden change in the DC offset voltage on the bad channel when he touches the bad connection. Then it's just a matter of resoldering the connection. Good luck on this one.

Yep. The wiring to your speakers or the speakers themselves have shorted out. You have a blown fuse. You'll need to either replace the unit or attempt to replace the fuse yourself.

I received a reply promptly from JVC to check power connections for shorts. O course I had already done that. So as a last resort, I pushed the power switch on and held it for maybe 10 seconds. It seems to have reset the unit, and it's playing fine. Best of luck, hope you all read this and it works for y'all. AJ

Anytime there is a short circuit or your battery down low enough you will recieve this signal. If you press the little "reset button" using a small pin or screwdriver your unit should reboot without the "PROTECT" signal. If seeing this "PROTECT" sign is a result of jumping your car, this will fix it. If the signal persists, then there is still a short circuit and you need to check your connection with the battery. Most likely it is touching the chasis or some othere metal.
