Question about Kenwood KDC-4019 CD Player
I have checked the fuses and connections to the radio and cannot get power to my faceplate.
There is power to the receiver itself as i can eject cd's, but i cannot get sound because the faceplate will not turn on. I recently had a lot of wiring work done none of which should have affected the stereo.
The battery was disconnected for about two weeks while the work was being done, I also had the faceplate detached during that time as well.
I have tried pressing the reset button and a combination of other bottons as well, with no sucess.
Just wondering if there is something else I should try or if the faceplate is just dead. And if that's the case then would a new faceplate fix the problem or would I need a whole new receiver as well?
Thank You Very Much
It sounds like the stereo does not have the "ACC" voltage. It could have blown a fuse. The "ACC" voltage goes to the red wire on the harness and you get that voltage turned on only when the ignition is turned on in the car.
The symptom of the disc ejecting and nothing else works is an indication that only the constant voltage for the yellow wire is connected. Check the voltage on the red wire with the car turned on, if you have that 12 volts at the red wire, then you need the radio serviced.
It is not very likely that the faceplate has gone bad. Just because the radio will not turn on is not an indication that the faceplate is bad. It could be a voltage regulator in the radio or a circuit trace is blown, or almost anything else. There are many reasons that the radio would have the problems you describe and it can only be found out for certain by troubleshooting the radio on a test bench with the proper tools. If you have a multimeter and a power supply I can guide you thru troubleshooting the radio and even email you the service manual in PDF format if you would like to take a crack at it yourself.
Let me know how you want to proceed.
