I have a Pioneer DEH-P8500MP that is about four years old. About two months ago I tried to open the face to tinker with the audio settings (only accessable with the face open) and the unit shut off. The face would then close and the unit would power back on, then the face would attempt to open, and it would shut off again. The cycle will continue until I pressed the open button before the face would open to cancel the open command to the unit. Does anyone have any ideas on a fix, or should I just invest in a new head unit for my car?
I also have had this unit for over four years. the exact same thing just happened to me yesterday. i was thinking maybe it is the motor that opens the face. has anyone found an exact solution for this problem yet?
It usually means the contact aren't meeting completely. I just grab the face and move it gently til the power comes back on. then, I press the button to open it up so that I can purposely move the plate and carefully line it up again and it should be fine as long as you don't keep removing the face.

when you take the unit out of your car and looking at the top of the unit there are two black screws. Remove those then remove the entire cd player cage by the 4 CHROME screws on the four corners of the cage the two in the front are in the two holes in the ver front (**use magnetic screw driver for this**) then disconect the two wire plug and the ribbon cable from the bottom of the cd player cage **BE GENTLE** there are two black tabs on either side of the ribbon cable. THEY ONLY MOVE ABOUT 1/8TH ON AN INCH using a jewler flat blade screw driver gently slide the clip out to un crimp the ribbon cable then once the cage is removed you can open the face. To open the face there is a white gear wheel on the rightn hand side of the unit you can rotate it with your thumb with a little effort. Rotate accordingly..... at that point you shouldnt have any problem but let my know if you do..
I think I got the second half of the solution for this problem. Please look at post "Unit powers down when motorized face opens" for a solution. Seems like we need to buy the ribbon that connects to the face plate to fix this problem.
you can try the following:
With the car off but iginition switch "on" ,press multicontrol until "face auto open"option comes. select "off" and see the result.
Press RESET with the iginition "on".
the default setting will be "auto open ".so select it "off".
For most Pioneer single CD players, you can set the clock using the following steps:
1.Press and hold the SOURCE button until the unit shuts off.
2.Press and hold SOURCE again until the clock appears. With some models you will press and hold the FUNCTION or AUDIO button instead of the SOURCE button.
3.Press the left or right arrow to select the segment of time you wish to adjust.
4.Press the up or down arrows to increase or decrease the numbers in the blinking segment.
5.Once the clock is set correctly, press the SOURCE button to exit.
