2 problems Kenwood KDC-7009 & Sony CDX-CA850X?

First the Kenwood. It seems I lost all function on the face plate. It will still rotate in and out when I turn the car on and off but once it's open I cant use any of the functions. I cannot even use the buttons to put the code in after restetting it with the reset button. Is there a fix for this problem that anyone may know of.

2nd problem, i used this sony deck to replace the kenwwod when it went and know the sony is messed up also. It will not pull in any radio stations anymore. It will work once I reistall the deck after being idle for a few day/weeks but then after a day or so I have no reception again. I have had this installed in my old car and now in my new/used truck and I have the same problem in both so I know it's not the antenna. I hope someone can help with these problems. Thank You so much for your time.
