This type of monitor has problems with the switches. The switches behind the push buttons malfunction after two or three year of use.
If the "OSD main control lock" and unlock appear, you have to change the ok push button switch. The switch it self is only 25 cents. However if you never used a soldering gun you should ask an experienced repairman to fix it.
All other problems are related to malfunctioning swithes with the other controls such as volume or brithness. I fixed the problem in 15 minutes and 25 cents

I simply unplugged the whole circuit board where the switches are on. The speakers don't work anymore and the monitors on/off-switch became useless. Of course no monitors menu will ever open again.
But the nervous flickering error message is gone. For free. I never used a soldering gun ;-)

Most of the monitors have a function to lock the OSD to prevent accidental changes in the configuration of the monitor.
If you are constantly getting the message about OSD being locked and unlocked then it means that the OSD locking button is constantly pressed.
Usually it is the "Menu" button on the monitor which is used to lock the OSD.
Check if the Menu button is constantly pressed.

The OSD button has gone faulty.
The button will need to be replaced , or it might just need spraying with a contact cleaner like RP-7 or WD40.
Both solutions will require the removal of the front cover to access the button.

Hi,

Press the Menu button ( marked OK) for one minute, or more, and a blue/red menu list should appear on screen.

Using the adjust button (immediately to the left of the OK button) by pressing the arrows at each end up or down as required you can enter the menu and select an action by scrolling.

At the end of the list of possible adjustments on the left of the screen (brightness, contrast, etc) is the Reset section.

On the righthand side of the screen is a flashing Yes No choice which automatically alternates.

The trick is to select the Reset choice on the left and while selected press the OK button when the Yes alternative on the right of the screen is flashing.

You VDU should then Reset and all will be well.
