How to Unlock a Sony DVD player DVP SR320 which displays "LOCKED" when eject/open button is pressed?

If the Sony DVP-NS77H DVD player displays "TRAY LOCKED" and you can't eject a disc or open the tray, try the following - First turn the unit off. Then, while holding down the eject, play and stop buttons simultaneously (on the front of the DVD player), turn the unit on with the '/O button (also on the front of the player). This released the locked tray for me.

You may have enabled the child lock feature, try pressing the Return, Enter and Power buttons together to toggle the lock off. If this is disabled and you still can't open the tray, turn off the unit and unplug it. After 30 seconds or so, plug the unit back into the electrical outlet. Attempt to open the tray. If this does not solve the problem, try pressing Power + Stop + Eject buttons together. Also try pressing Disc1 + Stop + Eject simultaneously (if a disc1 button is on the remote or player).

If the error message is t - L C K or persists after trying all of the above steps, then you need the unit serviced.

The manual is available at the Sony support site: http://esupport.sony.com/US/perl/model-documents.pl?mdl=DVPSR200PB .

I hope this helps.

Plug the power cord back into the electrical outlet and turn the player ON. Attempt to open the disc tray. Depending on the model number of your DVD player, simultaneously press the POWER + STOP + EJECT buttons. If the disc tray still does not open, simultaneously press the DISC1 + STOP + EJECT buttons.6 Jan 2013

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

Your system is in child lock mode. I had this exact problem this week. You need to put the system into standby mode and then press return, then enter then on/off and it will be unlocked.
