Question about JVC KD-LH7R CD Player

Not working "at all"...

Yesterday I was trying to fix this litle storage thing under my radio and while removing it I also disconected my radio unit . When finished I reconected but nothing seemed to be working . Its not a power loss cause when I press the "display" button it shows the time it seems to be "on" ... The other task it does is when opening to insert a cd it does, its just fine ... and eject it .. -but not play it . The tuner is also "dead" . Generally is not working . It has a reset button, which i presed but only resets the display time ... How am I going to find out whats happened ? The troubleshouting section of the instructions say that : when "the unit does not work at all" then "the built-in microcomputer may function incorrectly due to noise etc." And the cure is to reset ... But no ..!

    Greetings!! I have the same problem, but first it's started with the turner and then with the CD player. Some times the CD play and others not. I check DC power, check fuse, check the turner antenna, check the ground and still works in time to time. ¿¿What I have to do??. Thanks.

    i recently set up my subwoofers and amplifier in my car. i took out my panasonic cq-c1100u but didnt unplug anything i striped off an inch of wire so i could attatch my remote turn-on wire to it and electrical taped it so there were no bare wires showing. i pluged my RCA cables to the pre-out plugs and put it back in. now it wont even turn on at all. it said security behind the faceplate but the light wasnt flashing when i took it out. i need help. did it die on me or should i just get another player?

    i just put this radio into my new car. first time i tried it, it worked fine. now however it doesnt turn on. unless i press the display button when it only displays the time. what is going on ???

  • madmachines Apr 25, 2008

    Hi all. I too am having the same problem. I can put CD's in and they load, I can change between tuner, AUX, and compact disc - but no matter what I do, there is NO SOUND whatsoever. This just started happening. I have reset the head unit many times now but not one of the reset attempts helped any.

    Anyone have any ideas that might help? The only response to any of the problems I have seen posted is to check for power but I definitely have power.

    thanks for any help.

    My kid hit the on Volume button, and then the radio kept a high volume I stopped the Car turnrd of and from then my radio is dead.

  • william patterson May 18, 2008

    player worked fine one day, then next day it shows IT HAS POWER but no sound comes out. I have checked the wiring behind the radio, and it all seems fine....no loose wires. Would there be a separate fuse for the speakers for some reason? Seems like alot of folks have same problem but no one has a solution.

I have an eclipse ecd414 cd stereo. It has been out of my vehicle for several years. Now I have given it to my Grandson but I can't find the security disk. What can I do to get around this?

I had similar problem and found out I had blown a fuse when connecting the wire.

So I suggest you check your fuses first, if it is burnt verify your wire connection, correct as necessary and replace your fuse. This has fixed the same issue you all had described above (Display turns on and CD eject works but no power).

Another way to test/diagnose the problem is connect your old stereo; if fuse is burnt you should get no power to your stereo. Hope it helps

Does it have a remote? if it does, there should be "PWR" button. try that, it seems to me that you head deck is in clock mode. cheers.

You could try and disconect your battery for about 5 mins, this should clear any computer error's, and reset things, this may fix your problem.
