Question about Car Audio & Video

Open Question

Why won't my Emerson model # MS9920TT work? The little light on the power button is lit but nothing on the system will work?

I really like this system, and I haven't used it in a while, and when I went to use it, nothing would work or turn on, there seems to be something not connected, the power button's little red light is on but the rest of the system won't work. Nothing on it works I don't understand, I had it in the wall unit and its just dead. Please tell me that there is something that I can do. This little system is so compact and has everything I need in it, the turntable, stereo radio, dual cassette and 5 cd player. I await your response, thank you.

SOURCE: JVC car radio/cd player wont switch on

As a sanity check run a temporary wire directly from the battery positive to the radio. Twist the red and yellow wires together and connect it to the wire from the battery. If this works either your red or yellow wire connection under the dash or to the harness is not hot like you think. Yellow usually goes to a constant 12 volt source (to keep radio memory) and the red wire to 12volts when the ignition is on. In some radios this is reversed. The test I mentioned will determin if the problem is in the wiring or the radio.

Hi. You need to check a few things. make sure you have power on both the red and yellow wire with the key one. If only one has power the radio will not work. also make sure that you have a good ground connection on the black wire.. if nothing works yes you probhably have a bad radio. the dual brand radios are notorious for poor solder connections on the mainboard due to the way they build thier cheap circuit boards..

SOURCE: Red light on power button is on but player still won't turn on, help please!


At most that I can share with you are generic.

If this is a fairly new car/radio model - When your battery died, the radio assumed that it was forcibly removed from the original vehicle it was installed to. For security purposes, the radio will not be usable by anybody not unless re-initialized (security unlock) by the original dealer of the car. You need to bring documents as proof of ownership, VIN information, and all others as may be required to your car dealer who would then submit them to an online support that would verify authenticity of claim and if the "numbers" match. Thereafter, a series of codes and procedures would be given to your dealer who in turn would use them to restore the JVC to operational status. There is nothing wrong with the JVC other than it will not let the user use it.

There is no known bypass to this. There is however a modification that could be done to prevent from happening again.

If the car/JVC does not employ the above described security feature, then chances are that internally, the JVC has developed a fault. Since this would require opening the unit, electronic circuitry diagnosis and possible component replacement, perhaps your best bet would be to seek the services of a qualified auto audio technician.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
