Pioneer AVH5700-DVD carriage...

Hey all! First post here...

I have a Pioneer AVH5700-DVD (obviously, as the title has stated) and I obtained it through a friend for about $70 bucks, hoping I'd be able to fix the screan that wouldnt open or shut by the touch of a button... its currently in the out position, and I figured it was a gear.

From what I can tell, the gears are beat, and the carriage may possible be bent/jacked up. Anyone have any experience in fixing these, or know how to make it so that it will easily slide in and out, even without a touch button so I can get to using it? If you need pictures of the deck just let me know and I would be glad to get em out!!

Thanks,
