The ribbon cable is bad. This is easily repairable. I think Best Buy still does them or call your local electronics repair shop.

SOURCE: Another one with Faceplate buttons not working?

The capacitors in these plates tend to burn out quickly for being so hot and lack of air cooling circulation. You can test all connection pins on the deck and faceplate with an ohmmeter in ohm setting to see which pins is not sending 25-30 ohms or 5 volts of power

The clip that locks the plate into place probably broke.

Basically I have the same problem that has been displayed a lot on this site. My pioneer DEH-P7800MP display won't show when the face closes. When the face opens up all the buttons and lights and display...


The faceplate and head unit is is attached via a flat ribbon cable. (Caution only continue if you have some courage). If you open the faceplate you will see that the ribbon cable is seated in too a flat connector on the PCB (Printed Circuit Board). This connector has a locking mechanism on it that when locked presses the contacts of the cable to the connector. Ensure that the cable is seated properly and that the latch or the lock is in the locked position. Assuming that the tension lessons when the unit is closed so it draws away from the connector and when the unit is open it pulls tension creating a contact. If you see no signs of mishap on this end of the connector try the other end.
Hope this helps.
