Hi, I am Tech Michael and I will be assisting you today.
Please be patient as these are technical questions that may require a bit of conversation to solve. Also remember to be detailed in your description of the problem. That will help me make a diagnosis quickly for you.
Please try this for me. Unplug the unit form power. wait 5 full minutes. Then press and hold the eject button in on the unit (not the remote) while you plug it in, let me know if the DVD tray will open.
If it does please rate kindly. But if not, do not rate yet but simply reply to me for further information.
Thank you for choosing Just Answer.
