How to get rid of osd lock which appears frequently on screen?


Hold the MENU button for ten seconds to unlock or lock the OSD.

This information is from your manual for the L194WT:
OSD LOCKED/UNLOCKED
This function allows you to lock the current control settings, so that they cannot be inadvertently changed. Press and hold the MENU button for several seconds. The message "OSD LOCKED" should appear. You can unlock the OSD controls at any time by pushing the MENU button for several seconds. The message "OSD UNLOCKED" should appear.


Please rate me if this solution works for you

Thanks......Have a great time

The main menu appears and disappears without any input. And also a picture of a lock also appears and disappears without any inputs. The picture of the lock is either locked or unlocked


It seems that the problem is the monitor is detecting that the menu button is continually being pressed or the switch is shorted. Try pressing the menu button a few times to see if you can make this stop. Otherwise, the monitor needs to be repaired. Hope this helps.

Osd locked


On some display devices, there is an OSD Lock that locks all current control settings and prevents access to the control menus until this mode is unlocked.

The method for unlocking the OSD is different for different monitors, but will be one of the 2 below. If the first method doesn't work, try the second.

Method 1: Press and hold both the [1] button on the front of the monitor and the down arrow button for 10 seconds.

Method 2: Press and hold both the [1] button on the front of the monitor and the up arrow button for 10 seconds.

Note: These same buttons, when pressed for another 10 seconds, will lock the OSD.
