I have a MDS JE500 Sony minidisk deck. It has only been used only two times. I have two blank minidiscs in hand and when I insert them, the display reads out TOC READING for a bit before displaying EJECT and then ejects my disc. I'm not sure what is wrong with my unit and would appreciate for any help. :::EDIT::: Found out the servo mechanism for the laser needs a bit oiling. All is well.
