We have not used our DVD player in a couple of months. A DVD was left in it..it still plays, but we can't it open.. It says TRAY LOCKED...what's up?? It's obv not the child lock...as that just says locked..not tray locked...Thanks.. It's a Sony HDME.. DVP-NS77H

with your tray open, on the big circular button:
press 'up'
press 'up'
press 'down'
press 'down'
press 'left'
press 'right'
press 'left'
press 'right'
the region code will turn to '0'
enjoy

not sure if this link will help you. https://community.sony.com/t5/Blu-Ray-General/locked-blue-ray-player/td-p/113765

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.

Sound like it either has one or two problems, the door is stuck and or the door eject motor has failed. Look in the front to the player for a small paperclip like hole, and use a paper clip to manual eject the and engage the loading mechanism usually located under the door for most cases. Check you manuals troubleshooting section for manually ejecting a CD..
