Could there have been a disk in the tray that has slid partially off the tray during your move?
if tray will not eject you could try ...
1) Hold record & eject buttons while plugging the unit in....
2) There is a small slit under the front edge, where there is suppose to be access
to the release mechanism. If I recall correctly, a small thin screwdriver is inserted &
then a slide sideways will release the tray. (I have not tried this)
hope this helps
