If this is a "flip face" type of display then you may have a broken lead in the ribbon cable that connects to the main board from the flip face. This is a very common problem. You'll need to replace that ribbon cable.

I have a non-lighting Cobra 29 NW face plate, or EL Driver problem . EL Driver is the small metal box mounted inside, to the side, of the the Cobra 29 near the channel selector control . Can anyone tell me...


that is a power inverter. dc to ac inverter. 13-14volts to 40+ volts ac. to run the el display.. if the display is pulled away from the face like the glue is coming loose that indicates the el display is burnt and will not work unless replace the face plate the el face.. you should have 45volts AC on the two wires feeding into the main chassis face to the el display.

I have a Kenwood KDC MP532U. The face plate will not display.


it more than likely has bad solder connections inside the radio on some surface mount resistors usually located on the right front of the radio as it faces you.

Alpine 7835 display lights not working, everything else is fine


if it's not under warranty, I would advise taking the face plate apart and checking for burned spots on the board and using compressed air to remove anything that is conductive that may cause a short in the face plate. The face plate should be really easy to take apart.

KRC-703 display does not work, sound does?


Check to make sure the right face came with your unit, I had an alpine once that did the same thing when I accidentally grabbed my friends face plate. Everything worked but the LCD. Check the model numbers to compare

Face plate buttons wont work


This is actually a common problem with more than just that radio. Sometimes the pins on the back of the face plate need to be cleaned. Take the face plate off, take a Q-tip and dip it lightly in some rubbing alcohol. Then use that to clean the metal pins on the back of the face plate. Make sure it is completely dry before you place the face plate back on. If this does not work, your better off replacing the whole thing.

JVC KD -S680 needs help


maybe short circuit or similiar problem inside since its geting hot, probably not a problem with the faceplate I would remove the cd player from your car and take it to a professional for a diagnosis / repair estimate. Can't solve this one with text only.

Psp anolog button faulty?


You just remove the face plate again and check it now your PSP is working OK if so there is some misalignment while placing the face plate on PSP and suppose your fault still remains same without face plate also then there is a possibility of Analogue button is being damaged which should be changed.

Dropped the system everything working but will allow me to go to the map screen


Did you try to reset the unit? Place you thumbnail in the groove located under the Garmin logo on the face plate. Gently pull off the face plate. Press the reset button. Turn the unit back on and see if it works - Of course replace the face plate carefully. Good luck! Dr. Know
