Locked dvd on a panasonic tv/dvd/vhs combo

The AV OUT on your DVD player must go into the corresponding AV IN[PUT] on your TV.

I had the same problem. It would not release the DVD because it was not ready. What worked for me, was to insert a VHS Movie and play it for a few seconds, than stop it using the remote, then Eject with the remote, and then after removing the Tape, I pressed the Open/DVD button on the unit and now it worked, it released the DVD

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..

Please leave comment.

First of all,i don't know if you have a combo dvd/VCR player or two separate units.Secondly,please tell me how you connect your dvd/VCR combo OR DVD player and VCR player to your TV.

During stop or power off, hold the stop/eject button on the unit for at least seven seconds.

Combo's, Another method
With unit on and no cassette inside, hold the rec/time button on the front of unit for 7 seconds.

Only the on/off button will work,the others have no effect. Press the action and power buttons at the same time on the front of the set for 10 seconds or so.

Press and hold the Volume down button on the front panel, press the OK button on the remote for 5 seconds.

DVD's Lock Mode

The sales demonstration lock function is set by simultaneously pressing the "POWER" button of DVD Player on the remote control unit and the "STOP" button on the main unit. ("LOCKED" is displayed when the lock function is engaged.)
Release Method
The function can be released using the same procedure as for setting. If the remote control unit is not at hand, the function can be released by using the same method as for player initialization (pressing the "PAUSE," "SKIP/SEARCH<<"and "OPEN/CLOSE" buttons simultaneously).

VHS-DVD Recorder (DMR-ES40V), Forgotten Ratings Password
From the Owners manual: Open tray, Keep Pressing Rec and Play/X 1.3 buttons on the remote for 5 or more seconds.

This machine does not support DVD recording. Are you trying to make a tape from a DVD, by some chance?...accordianman

turn of the power on wall, and wait 5 mins, then try again. i had same trouble with not being able to eject or play dvd, i turned off player at wall and it worked fine again.

I just found my solution. I pressed the power button on the remote and the stop button on the tv at the same time, and it unlocked the dvd eject.
