Wrong faceplate on Pioneer DEH-P6900 UB - Now it won't work HELP!!

Okay my brilliant 17 year old son thought he would be funny and put his Pioneer faceplate on my Pioneer DEH-P6900UB unit to play with. Well, thinking it wouldn't fit, I didn't even attempt to stop him. Unfortunately it did, and though we thought we weren't going to get it off, pushing different buttons finally ejected it. Problem is now mine won't work. My dial will turn on and light up blue, if I put a cd in and I turn and turn all the way up I can hear static music. But I don't have any information on the front of the unit. I tried to hit the reset button, which doesn't work. I called Pioneer and he said to unplug the back, let it sit for about 30 minutes to let the capacitor drain and then plug it back in to see if it works. He said if that doesn't work I'll have to take it in. What will they do that I can't do. I can't believe this is the only time this has ever happened. Somebody please tell me you can help me. I don't want to buy another unit for a stupid mistake.

    I am going to try to leave it unplugged overnight. If it works I will post it in here for others.

    If anybody else has any ideas I would like their advice too.

Pioneer can look at the interior components. Your son probably messed up the configuration of the device or possibly even caused a short-ciruit by plugging in his faceplate. If your product is still under warranty, I would highly recommend turning it it, after all, it's better than buying a completely new one.

Pioneer will find the problem, and fix it. If for some reason they cannot find the problem, then they will send you a completely new device.

Also, here are a few other forms that may, although most likely won't, help, but It's worth a try:

If you still don't want to take it in to Pioneer, then I would try unplugging it for at least 24 hours because most of the time 30 minutes is no where near enough time to completely drain the capacitor. Unplugging it for this long will also reset the configuration completely, which may be the problem right now.

My last suggestion is to try to put your son't faceplate on again, and see if that works. If it does, then there is no short-circuit. If it returns the same result, then you must take it in.

This is some advice that is simple, but may also be the case: It may be a bad CD. If you haven't already, try playing a different CD and see if that will work.

I hope this will help, and good luck!

They might have access to firmware in the unit that is not user serviceable.

I'd try leaving it unplugged overnight first, though, to really test the capacitor reset theory. I think that might work.

make sure that you have power not only to the red wire but also the yellow wire... one is battery power the othe ris ignition on power. If it only is getting one power it might not think the ignition key is on.. also maks sure there is not a reset button somewhere that you can press with a pen...

Did you format it while connected to a PC? If so check that you didn't format as NTFS, the Pioneer HU can only read FAT32 I think.
