Sony CDX-F7705X -Static Noise-

I've had this stereo for awhile. Never had problems. I play alot of burned cd's. Have used many different brands of cd-r's. Burned them from iTunes and Windows Media Player 11 etc. Now my stereo has alot of static in the backround when I play my burned cd's. Sounds like a bad radio station. It has even done this with my regular cd's (not burned). I've tried three different cd lens cleaners already. No change. Sometimes it won't play at all. It tries to read the cd and then shows "ERROR". The stereo also seems to get very hot. Not sure how warm they should get.
Please help. I am looking for a new stereo and would rather not, but if this stereo is on it's way out.............there I go.
