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, the display shows "LOCK" and we cannot get the tray to open. We are unable to find reference to a "lock" function in the manual. Can you help?

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.

I currently have a DVD in and it won't eject. I have a Samsung HT-Q100 System
Turn off the DVD player completely. You MAY have to turn off the tv too. Let sit until you count to fifteen! Turn back on, tv first, then DVD player. You should be able to eject the disc then.

Samsung HT-A100 Home Cinema system plays cd only with tv on!
Hi,
You need to put away the remote for your TV and use only the remote for your HT system. Your HT remote should work on your TV by default. Your Samsung HT remote should have a TV button and a DVD/Receiver button (or HT button). When using only the TV, press the TV button and then use it for just the TV and when using the HT system, press the DVD/Receiver button and then you can use the HT system.
If for some reason your TV is not set on the Samsung HT remote by default, your HT users manual should have a list of codes that you can use to program your HT remote. Hope that helps you. Gary
