Question about JVC MX-KB30 CD Shelf System

2 Answers

JVC mx-kb30 Stereo comes on then goes right back off.

When you turn the JVC mx-kb30 Stereo on, it says welcome, aux in (or CD or FM), goodbye, and cuts off, and back to clock display. I have unplugged, but no go. It simply won't stay on for more than a few seconds before shutting off. I'm out of ideas. All the buttons, lights, and displays work, it just won't stay on.

    When turned on, displays "welcome," but a few seconds later says "goodbye" shuts back off. Tried various locations, with no change in issue.

I had the same issue on a ka30 - was about to junk it and decided to take a look under the housing.
There was quite a bit of dust on the circuit boards, as well as some cobwebs. I blew all that out and it works like a champ again. Make sure you unplug it before taking the housing off. Hope this helps.

A desperate longshot but the only i have to offer: It might be a problem with the electricity. if possible try and install it at another location in your house, using other electricity sockets. If the problem is solved by relocating the system, you might be looking at wiring problems (audio equipment can be very sensitive to that), if changing anything in the installation process solved the problem then the problem was probably due to bad grounding and "loose" electricity. Try making the installation as "clean" as possible, avoid tangled wires and stressing a single socket with too many electric appliances. If the problem persists, and you are still under warranty, I suggest contacting your local JVC dealer. If you're out of warranty I suggest locating a professional repair person. Good luck

My JVC MX-K3 Stereo System Displays "PROTECT" when it's Turned On. What can I Do 2 FIX This?

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.
