Also, for those asking about the eject button not working - if the unit is "busy", (e.g. trying and re-trying to read a disc), the button may be ignored or it may take a *very* long time as it waits until the current task is done, which may never happen if the unit is bollixed in some other way.
However, if the unit is even halfway functional, you can press and hold the eject button for 5 seconds or so which tells the unit, in essence, "gimme it anyway!"
There's a few possible outcomes then depending on what problems the unit is having, as follows:
- you get the cartridge with all discs
- you get the cartridge minus the one which was selected and you'll probably have to disassemble the unit to retrieve the missing disc
The first case means either an electronics issue or a major mechanical issue (i.e. something overtly broken, dislodged, unplugged, fried etc)
The middle case means that the "big" mechanical bits are probably okay and probably the electronics as well, you likely just have a stuck head, dirty lens etc
The last case is indeterminate but leans more towards a mechanical issue of some kind
First and last obviously require disassembly/repair or replacement. The middle may just need a cleaning disc.
