To get the tray out for inspection try straightening a paperclip. On the face of most disk players there is a small hole. Push the paper clip into the hole, and the disk tray should release. Pull the tray out to it's full extension. Power being on or off is immaterial. Hope this help.

Sometimes the medal lid on top will get bent and put pressure on the disk tray. Try removing the top and see if the remote will work then.
