I have a pioneer deh-p7800mp,it works fine but it has to have a gap so it will turn on,when it does shut,it shuts down,no music or anything,could it be the ribbon or something deeper in

Yes, the ribbon cable has been a problem with these. I searched around and found the cable on Ebay and replaced myself, pretty easy actually. You can also take it to a repair shop. I think Best Buy can do it.
