HU wont turn on.. or turns on then off.. help? :(
Wednesday, July 19, 2006 3:29 PM
I was driving home from work today and my headunit (Pioneer AVH-P7600DVD) decided to suddenly stop working...

It was working fine since it was installed about a month ago, but on my way home tonight my subwoofers and it sounded like my rear speakers quit working. Then about 30 seconds later the headunit shut itself off and I can't get it to turn back on. Usually it just sits dead, but once in a while I can get it to turn on for about 5 seconds by putting the car into ignition, but it shuts itself off before it transmits any audio to the speakers. I checked the fuses and they seem to be ok, and none of the other electrical components of the car appear to be affected, just my audio..

I have a buddy who dabbles in electronics coming by this weekend to take a look at it but i'd like to get some ideas as to what might be wrong with it before he gets here.. anybody have any ideas?

Thanks in advance guys. Any help is appreciated.

A little while back my ground came loose and everything turned off, pissed me off. So I got out and looked at everything, everything looked good, then I checked the ground and there was the problem. The ground came undone. So I reconnected it and poof, everything came back on.


GIT 'ER DONE!
