    Yeah, same thing happened on my unit. Personally, I think the screen just burns out on these faceplates. This is such a nice sounding radio. It is a shame that the put such shitty screens that burn out after about a year or so on the faceplate.

    I have the same problem but when I open the face plate to put in a CD the display works.

    I am also having the same problem. it seems like the ribbon cable that connects the display to the radio is worn out. Does anyone know a part number from Pioneer to order a replacement ribbon cable?

    does anyone have another solution other than wiping contacts? Didnt work for me to wipe it down.

    Sorry can't help, but if you can't fix it and would like to sell it, let me know. I need the parts for an audio project I'm working on. Email: audiohost@hotmail.com. Good luck regardless :).

    Guys, i had the same problem and found that the flex cable gets a split in it after opening and closing, the flex cable cost around 30-40 dollars.

I found the solution to the problem for my unit. There is a ribbon cable that connects to the front plate where you snap on/slide off the faceplate. This cable actually wears out from opening and closing the CD drive. I had to take the unit in for repairs and it cost about $150 to replace the cable. Once my radio was re-installed, I promptly turned off the function that opens the unit every time I turned my car off. I figure the thing opening and closing the CD drive every time I went in and out of the car was wearing the ribbon cable out. So it was NOT the faceplate like I thought. It was the ribbon cable that attaches to it from behind the faceplate connecting harness.

Now the only other quirky thing this radio does is some of the channels go out. Then I just move the volume control and the speaker comes back on.

I tell you, this radio was NOT worth the $300+ I paid for it. Plus the Pioneer people on the phone were not very helpful.

I would avoid this unit if you see an old one for sale.

I have a pioneer deh-p7800mp,it works fine but it has to have a gap so it will turn on,when it does shut,it shuts down,no music or anything,could it be the ribbon or something deeper in


Yes, the ribbon cable has been a problem with these. I searched around and found the cable on Ebay and replaced myself, pretty easy actually. You can also take it to a repair shop. I think Best Buy can do it.

You can get replacement wiring harnesses from Pioneer (www.pioneerelectronics.com) or from a local stereo shop that sells Pioneer product. Also, check Ebay...there are often times harnesses for sale for any model of radio from all across the country.
