Measure to be taken when a disc cannot be removed due to a mechanism trouble
First, remove the mechanism unit section from the set, and check for the state of the disc.
(Remove the top plate R if necessary.)
<State of the disc>
(1) When the disc is in the normal PLAY (chucking) position 
 Try to eject the disc by turning the mode big gear/tray big gear
manually.
* At this time, be sure to adjust the tray's position (height).
(2) When the disc is in the normal STOCK position                
Try to eject the disc by turning the tray big gear manually.
* At this time, be sure to adjust the tray's position (height).
(3) When the disc is not in the normal position                       
The tray or disc is not in the normal position.
(The tray or disc may catch somewhere.)
Remove the TOP PLATE F/DISC OB lever.
Unlock the tray lock lever and pull out the tray which is not caught.
Move the caught tray or disc and remove the disc.
In case of (1) and (2), the mechanism is normal (defective circuit parts, etc.). However, it may stop somewhere.
This is the reason why you should try to turn the tray big gear first.
In case of (3), either of the big gears does not turn.
