eclipse avn7000 issues

tonight, i started the truck, and i accidently hit the screen while it was popping out, the unit worked fine for about 10 minutes, but then all wierd stuff happened... the screen went back in then pop out again on its own, i try to go to the next chapter on the dvd, and it would just fast forward and not stop. the color would change from blue to purple (it only does RED / blue im assuming its in the middle of that) i would try to mess with the volume, and it takes a while to register that, and it would just close and open again. what do you think would cause such a thing? any help would be awesome! i think i can just get a new face plate, the face plate on these are pathetic, just the lower half of it comes off and it looks like i could use it in another unit.

thanks in advance
