Question about Pioneer DEH-P4700MP CD/MP3/WMA/WAV Receiver

The radio plays the CD but the faceplate is dead

Hi, some people is saying that maybe the faceplate is not making a good contact with the connector, but I don't think so, because it happened after the car suffered a short circuit in the ignition switch ( The faceplate wasn't there by the way ). Days after my mechanic fixed the problem I tried to hear music, but I don't have control of the radio because the faceplate is dead. There was a CD in the radio that still is playing with a standard volume...

It sounds as if your i/o relay for the control face is toasted and part of the relay is welded and carboned. you will need to replace it or chances if this burnt therre may be more behind this such as the amp if equiped. gl

Maybe the radio need to be reset. Try disconnecting the battery cable for 5 to ten minutes. If that does not work, the radio will need to be serviced or replaced. Good Luck

The face plate does not light up anymore on my Jenson CS2010X so I can't see the stations. How to fix this?

You might not be able to fix this problem. But first, here is a sugestion you can try. Remove the faceplate and inspect the metal contacts on both the deck and the faceplate. Each contact operates a different function of the radio such as providing power to illuminate the faceplate. Make sure no contacts have been broken, pushed in, or have corrosion. Once they all look good, replace the faceplate and see if it lights up. If not, its an internal problem with the unit and should be professionally repaired or replaced.

Jensen MP5720 radio/faceplate connector is broken or missing spring

I was always afraid this might happen to me so I never removed the faceplate from the radio. This strategy worked fine for two years until two weeks ago. I didn't lock my car because of the freezing rain and somebody stole my faceplate and remote. Anyway I ordered a replacement radio from Amazon last week so I don't have rewire a new one. The replacement cost me $100. I don't really need the rest of the radio so make an offer, my email is [email protected]
Regards, Chas

Panasonic CQ-C7103U having faceplate attachment issues.

You can order a new faceplate from Panasonic, if that is the problem. (You may find one on ebay, too?) Carefully check the connection before spending anything, as I wouldn't want to suggest spending on something that isn't broken. If you have electronic skills, check the internal connections from the jack to the internal board and every other connection. Also look for cracks in the board. If found, a light coat of solder can fix that up fairly well, and not cost anything.

Of course, this is all a guess, and I would verify everything yourself before doing anything. Good Luck.

It sounds like a bad connection between the faceplate and the unit. Have look at the way the faceplate connector makes contact with the connector. You may be able to bend something to make it make a stronger connection. Also check that the contacts are not dull or dirty.

Faceplate won't connect


There are possibly three (3) ways of making sure that there is contact between the faceplate and the unit's frontend:
1. normally, what it would take would be cleaning thoroughly and a light application of WD40 to the mating contacts;
2. slightly bend out the elbow type pins. This should be done carefully so as not to overdo and bend it out of place; or
3. solder a thin layer of soldering lead on top of the flat contact points to increase the contact height. Light/Low heat soldering iron must be use to prevent burning the plastic surroundings.

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

Good luck and kind regards.

Thank you for using FIXYA.
