Try restoring your unit to factory shipping conditions:
Press stop button on the main unit and (>10/ENTER) on the remote control at the same time for about 3 secconds, you would see the message "Initialized" on your tv screen, Once the message disappears from the tv, let go of the buttons. Try this and let me know.

The system has a locked / unlocked toggle sequence on the main unit by holding down stop (or Play) and then tapping the power button. Use this sequence lock or unlock the DVD / CD drawer.

This unit has two locks for demonstration purposes so discs can't be stolen.
Eject lock:
With the unit powered on, press and hold stop button and power button on main unit for at least three seconds until it shows unlocked.
Function lock:
With the unit powered on, press and hold play button and power button on main unit for at least three seconds until it shows unlocked.

Hope this helps.

We have a Samsung Digital Home Theater System HT-DM150. After some guests were fiddling with the remote, we find that we cannot eject a DVD that was inserted. The DVD plays OK, but when we try to eject,...


Samsung Home Theater Systems have a Dealer Lock or Tray Lock Function that prevents the disc tray from being opened.
There are four procedures for turning off the Dealer Lock function. Try one, then the other, to see which works on your system.
Unlocking Procedure 1 To turn off the Dealer Lock function, follow these steps:
  1. Turn on your Home Theater System.
  2. Press the Stop button on the front panel and the Power button on the remote control simultaneously for four seconds.
Note: Repeating the two steps above turns the dealer lock on again.
Unlocking Procedure 2 To turn off the Dealer Lock function, follow these steps
  1. Turn on your Home Theater System.
  2. Press and hold the Function button on the front panel for 3 seconds. The display shows the word Unlock.
Note: Repeating the two steps above turns the dealer lock on again.
Unlocking Procedure 3 To turn off the Dealer Lock function, follow these steps
  1. Turn on your Home Theater System.
  2. Press and hold the Open/Close button on the DVD player on the front panel for more than 4 seconds.
Note: Repeating the two steps above turns Dealer Lock on again.
Unlocking Procedure 4 To turn off the Dealer Lock function, follow these steps
  1. Using the HTS remote press the Menu button + 712, and the HTS will display CAN OPEN.
The Dealer Lock feature is mainly used by retailers to ensure that the display discs are not removed. However, parents of young children may find this feature very useful as well.

Scpt960- i am not able to open the disc


Try cold start.

Power off main set manually by press power button on main set.
Unplug power cord from main set.
Wait for about 5 sec.

[Without plug in power cord] Press and hold "Power" button without release it.

Plug in power cord (must have power) to main set by using another hand [while another hand still press on main set power button]

Keep holding until u see ------ on main set FL display.
Then release you hand which just now pressed on main set.

Power on main set again by manual press power button on main set.

Result should be OK (unlocked)

DVD player is "LOCKED"


Well, at least the child-lockout works, right?
I have a similar Pan. HT system and I suspect you will have to go through the main menu and look for settings regarding 'tamper-proofing' to prevent just such 16 month-olds from inserting their jelly bread into the DVD player.
Your system may differ from ours but you should be able to find that feature in your user manual.
If the manual is gone, you might want to try this page:

http://www2.panasonic.com/consumer-electronics/support/Audio/Home-Theater/Home-Theater-Systems.list.75434

Your system is not listed directly but there are several from that series and they may share features.
Downloading of the manuals costs nothing.

Good luck-
