Stuck disc in JVC CD player

what you have to do is ejecting the tape, and as soon as it starts to eject , close the door immediately, then safeguard mode should be gone, and you will be able to eject normally.

What model Bose CD player?

Find the Bose manual at Bose.com

if the eject button doesn't eject the disc the the CD mechanism is most likely damaged

I just had the same problem with the same model. Disc five was saying no disc and would not play any other discs. I opened the radio and found the the CD tray was missing a piece for disc five. You have to put the disc tray back into the holder to fix it. Make sure it locks in place and you should be able to get the rest to work.

I would pull off cover, unscrew and remove top carriage of tray and remove your disc. While your at it you should take cotton swab and dip it in rubbing alcohol and clean the laser lens. Then reinstall carriage and top cover and try using it again.

No solution - plastic thread driving opening/closing had snapped after 16 years!

Hi, did you fix this problem?
I'm having exactly the same issue myself.

try to open by hand,see if the tray is stuck.
opening by hand is you turn the motor.
if you put a power supply direct to the motor the pcb will be burnt
(giving a bigger problem).
Look for mechanical problems.
