you have to take out complete unit, unplug top cover and look for any "placeless" bearing, put some anti-static grease (white one), power cord the unit and eject the cd, if it doesn't come up then use a screwdriver to help the mechanism don't push too much since it is kind of fragile, this kind of problems are most of the times becuase of not using to much the cd mechanism, I mean this problems are common with MP· players or if you use Ipod then bearings because they stay in the same place they don't move and grease gets gummy (grease gets hard), once you have your cd out, use original cd's little more than before, in this way you will have to change cd more often and mechanism will stay in good shape and if you want to use MP3 cd's then try to use music designed ones, like samsung's, other cd's like verbatim's office depot's whatever are kind of heavier.....bearings gets damaged...
