Locked dvd tray.

The Disc Tray is Locked
If the message “Tray Locked” appears on the screen, the retail lock feature has
been accidentally engaged. To unlock the disc tray you must press and hold a
combination of keys simultaneously:
On the front panel of the DVD Player, press and hold the STOP, ON•OFF and
OPEN•CLOSE buttons for at least 3 seconds.

I forget the password Your player is equipped with a “back-door” unlock sequence. Press and hold
the STOP button on the front of the DVD Player and the STOP button on the
remote control at the same time. (Hold both buttons down at the same time
for at least 3 seconds).

Press Setup then the numbers 2 0 0 5 then setup and it should unlock
or
Display 2 0 0 5 Display

Do not have better news. You can unscrew the player, and see if dust is stuck in the gear that controls the dvd opener, or check the online dvd repair guys. But, really, it is cheaper/less of a hassle to get a new one.

with the unit off press and hold the stop button and the eject button.

Hey I just found out how to UNLOCK the tray
Power up the unit, wait for it to read the disc if one is inserted.
hold the stop button and the power button down together for 5 seconds
the display will show UNLOCKED
Open/close button should be restored

Press stop and eject buttons on player for 6 seconds, display will show unlock message and job is done.

Push and hold down the Open/Close button until "UN-LOC" appears on the FL display (or "Disc Tray Unlocked" appears on the TV screen).

Hi SoraTotoro,

This sounds like the child lock has been inadvertently activated . Look through the manual to find the key combination to unlock it.

Hope this helps.

Spare head 2.

Press and Hold EJECT Button, While UNLOCK Is Displayed :-)

To unlock, manually press and HOLD the open/close button & the stop button simultaneously, and HOLD them both down until the lock picture disappears.   The DVD will eject when you press the open/close button. 

 

To lock the DVD inside the machine, repeat the same step, and it will lock it inside.
