Question about Televison & Video

9 Answers

I have a DEC television that froze on the blue screen when you first turn it on, with a padlock and keyhole icon in the top right corner. It does not move past this to sound or picture and can only turn on and off.

    I have tried turning off and unplugging for a period, with no success.

  • Bob Jones Nov 22, 2008

    I have turned it off and unplugged for one hour with no success.
    If the channel has been accidentally locked, would it show up at the blue screen? How do I unlock if it is this problem?

    Have tried the TV/AV input and a DVD player connected to get a visual, with no success.

The lock symbol that you see is the lock for the tv , so that no one can watch( like your kids) or even use the video
there should be a lock button on the remote , press it to unlock it , unless you made a code then you will have to enter the code when you push the lock button

You did not mention the model but on many of these units only by the remote can you unlock the child lock, there is an "F" Button on the remote and while holding it down, press MUTE.

If this does not do it, write back and we will try some other approaches.

Blue screen usually means you are set to one of the video inputs. On the remote control, push the button for input selection.

If that does not switch you back to tv, do a hard reset and try again. (Hard reset: Unplug the power cord for 4 hours).

If you have a dvd player, connect the video into each video input one by one; you will see video playing when you are connected to the input that the tv is set too!

I think you have accidentally pressed any channel lock button as it is showing padlock and keyhole. These icons are normally shown when the TV or channel is locked.

First, please check this and then reply if it is the problem.

    as its the internal setting problem.calling a service technician is much advisdable instead of getting the unit  more damage by trying different solution.as it just needs the proper settings to make it oproper remaining everything is absolutely perfect.

Padlock, blue screen


Somehow in handling the remote control I pushed a button or combination of buttons and now have a blue screen with a lock symbol in red in the top left hand corner. I've tried turning the tv off, and unplugging it, as well as a combination of buttons on the remote, but it still is there.
What do I need to do to remove the lock?
