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).

SOURCE: jvc home component mx-kb30 protect mode on

First check that the speaker wires are not shorting, if okay! the problem is in the audio output stage of the receiver, the protect mode comes on if a load is detected.

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!

My JVC mx-g50 component flashes a PROTECT sign everytime I press the power button.Why?


Hi Robert,
Unfortunately, your unit has a built in microprocessor that is very susceptible to electrical interference like power outages and lightning. JVC recommends that you unplug and plug your unit back in like that's going to work. Might be time for a new unit.

FIND THE CODE TO GET RID OF THE WORD PROTECT ON MY JVC RECEIVER


Protect is displayed because there's a problem with your speaker wiring or there's a speaker shorted out. It's not there to tick you off for some reason.

So, you don't need a code. What you need to do is go sort out your wiring because somewhere there's two cables touching and the amp is trying to save itself from blowing up because you wired something wrong.

My JVC CA-MXKA3 it say protected when i switch it on, i have also try to switch it on weout speakers but it still say the same thing. Please help me on what to do

Generally speaking, an amp protects itself from heat, shorts and overloads.


Overloads can be from excessive periods of high output 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 hands-on tech.

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

One of your negative wires are most likely touching a positive wire. Very common.
