Won't turn on deh-p6800mp

My head unit deh-6800mp was working fine until one day it completely refused to turn on. The box (I don't know what its called) it plugs into has power because it will still eject the head unit when the car turns off. Plus I can hear something moving whenever I press the reset button the head unit. Anyway I have no idea about this thing, it appears it has no power going into the head unit itself. What options do I have to fix this?

SOURCE: Pioneer DEH-P4800MP - Can not get into INITIAL mode to change settings

Actually, TRY powering OFF the unit, and release the volume button. Then, press and hold ONLY THE VOLUME BUTTON, until the initial settings appear. Pioneer really needs to get their act together on this issue. I have read all over that MANY people have had this issue, and the website is just a repeat of their lame printed manual.

Hope this helps. In review:

From OFF, press and hold ONLY THE VOLUME BUTTON. The initial settings shall appear at this point after about three seconds...

I just read these instructions, and while trying it, I found that my FUNCTION KEY had ABSOLUTELY NO FUNCTION IN THIS.

Have you checked the fuse at the back of the head unit. You will need to extract the head unit from the slot. There is a small blade fuse near to where the wiring harness connects to the back of the unit. Check it to see if it has blown. It normally is a red 10amp fuse.
Also check your main fuse board.

Hope this helps
Regards

I have a problem with my pioneer DEH-6800MP /XN/UC. I have my 12 Volt inside, and it goes on to the first resistors. what else can I check? how can I be sure of my display is working? it would be great...


did you test that there is 12 volts? do you have a multimeter to test it? make sure the connections are good. make sure it's grounded properly, the circuit needs to be complete to have the display working.

Face plate went out on my pioneer deh 6800mp


There is a fine strip that runs from the face to the circuit board. It is possible that face has gotten dirty just needs a can of compressed air or the circuit board has failed inside the face. The face plate is very easy to take apart and put back together, just make sure you don't lose any pieces ;) Good luck!
