Switches off when playing a cd. Fine on radio

Replace the ignition switch.

Reset the radio by pressing a sharp object (pin, pen, etc.) into the small reset hole on or behind the face. If it doesn't have one, disconnect the negative cable from the battery for two minutes and reconnect. If you still have this problem, the radio is bad.

check speaker plug with the cd

It sounds like you may have a bad switch. If you have a multimeter you can check the switches for resistance. If the reading on any of the switches is less than a few megaohms it is probably bad.

look for areset botton if it dosent have one by a cd cleaner if after that its the same replace the radio

did you clean the laser inside? that a thing I would do first
after that mail us again

I had the same problem, the cd refused and radio plays good, with JVC KD G321. I have disconnected the switches behind the radio and also disconnected the antenne (do not forget the antenne) and it played the cd again.

Hi Cassiel,

You have it wired wrong. The Power Antenna wire is for antenna only. When you go to something other than Radio, the antanna wire signal to turn retract the antennaor turn off your amp. you need to use the Blue wire coming out of your CD player. The intended function of the Blue is remote turn on when every the radio is turned on. This will keep you amp on as long as your Radio is turned on. Change the wires behind the radio from the Power antenna to Blue Remote wire.

when i press the play/pause button discU pops up on the screen and the cd player will not play. Help!!!!!!

other than just double checking your switches settings there really isn't much you can do ,as there really isn't any easy to replace parts inside and that would be cost prohibitive anyhow , but do remember it is a clock radio , if its set t o use the alarm the radio will not work and not the cd either , ck all your switches for proper setting , one may have got bumped by you or cleaning staff
this is the reason I use a sound bar/phone dock as I use it to charge my phone and play music all day at my desk , they only cost about fifteen bucks to buy , and best thing is there's nothing for anyone to mess with when im not there as it wont work without my phone docked in it !!
