SOURCE: protect problem

I'm not really familiar with your specific model, so I don't know what the output stage looks like. I'd guess that this unit has a large black 'amp-pac" for the amplifier section. This should be attached to a heat sink in the rear of the unit. Look to see what the markings are on that part. I expect to see STKxxx. Can you post that here?

Thanks,
Dan

SOURCE: My JVC mx-gc5 stereo says protect and then shuts off

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).

JVC MX-GT88 sound system showing protected them shut off why


Chances are that something is blown in the power output stages and units shuts down to protect against further damage.

Repair or replace, which ever is cheaper!

Turn it down or it will turn itself down permanently.

Read the paragraph labeled "CONNECTION" on Page 2 of the SP-MXG70 (last) part of the document.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Everytime i turn my system on the word protect comes up and the system shuts off Can anyone help?


A short somewhere, most likely to the speakers. Check their cables and how they are connected.

Sound problem


I found out that it was simply my speaker connection. That is, it seemed like a good contact, but in fact the stero was reading "pulsing" from the speakers and shutting off to protect itself. I simply cleaned off the wires and carefully reconnected them.
