Question about Pioneer DEH-P850MP CD Player
CANNOT ACCESS REAR FACE PLATE WHEN I PUSH THE OPEN BUTTON FRT FACE PLATE OPENS AND CLOSES OVER AND OVER UNTIL I PRESS RESET. IT OPENS TO THE POSITION THAT IT OPENS TO WHEN LOADING OR EJECTING A CD BUT CLOSES RIGHT BACK. MY MAIN ISSUE IS NOT BEING ABLE TO FINE TUNE AUDIO OR CLOCK. ALL AUDIO CONTROLS ARE ON REAR FACE PLATE.
How to disarm DFS alarm How to disarm DFS alarm Disarming alarm Upon entering your vehicle and within the ENTRY DELAY TIME set within the DFS alarm Menu, attach your Pioneer Detachable face. If you have forgotten the Detachable Face Panel: If the STARTER DISABLE is ON, insert the ignition key in the ignition within the ENTRY DELAY TIME, then turn the key from OFF to ON 5 times within 1 minute. If the starter disable is OFF, insert the ignition key in the ignition and turn the key from OFF to ON within the ENTRY DELAY TIME. CAUTION: If the starter motor will not run, the cause may be the DFS alarm. To check whether the DFS alarm is cause, try switching the position of the switch installed according to the AVOIDING TROUBLE section of the installation manual. If the DFS alarm is the cause of the trouble, then the starter motor will run. In case, confirm DFS alarm operation in safe place. If there is no problem, switch back to its original position. If left at the newly switched position, some functions of the DFS alarm will not operate. If the starter motor will not run after switching the switch, something other than the DFS alarm may be causing the problem. Have the vehicle checked at a nearby dealer. ----------------------------------------------- Select the DFS alarm feature ON/OFF mode (alarm ) in the initial setting menu. Press the arrow (up) button to switch the DFS alarm feature ON. Press the arrow (down) button to deactivate the DFS alarm feature. Press FUNCTION button for 2 seconds to enter the DFS alarm setting menu These are a couple of things I found to fix this problem.

Check the ribbon cable on the inside that connects the two parts.
You will need to remove the faceplate and open up the Rear of the unit.
If you bought it used, theres a good chance that the ribbon is in fact broken. If its new, check the connections on the ribbon cable.
It is a chronic problem with most all PIONEER units that fold down / out.
Best of Luck.

there is a broken ribbon cable that needs to be replaced. parts and labor shouldnt cost you more than a 100 bucks. worth it since it never has the problem again
