Dont take apart the monitor!?!?! Hold the Menu button for about 15 seconds, the manual said 10 but i found by holding menu for 15 seconds it removes the OSD lockout.

Hello everybody,

I know how to fix this, but it involves opening up the monitor....

First unplug the monitor and get all the cables out. Then get the monitor of its monitor stand, this is done by unscrewing the four screws at the back of the monitor stand.

Now you can pry open the case with a flat screwdriver. On the inside you see a small electronic board with the power switch and the other switches on it. These 'broken' or dirty switches are what causing the OSD lockout.
Get the small board out of it's bracket and use some ETHANOL or ALCOHOL (atleast 70% pure) to clean the switches, you just spray or drip the ethanol into/onto the switches. This will clean the switches of any grease residu. Then spray the switches with air out of an airspray can untill they are totally dry.
Now you can put everything together and voila! it is working again!! atleast it worked for me :):)

This fix will only work if the switches aren't broken but only dirty or a little bit stuck, if they are broken then you would have to solder new ones on the electronic switch board.

Good Luck!

I find the only soluion for the OSD lockout message is to hold the power button down after it has been lit. I use a bulldog clip to do that. I think it is a crude way of doing this. But it helps in my case.

OSD Locks Automatically


Power off your computer and then remove the monitor cable from the port on the back side of the computer case.

Reattach the cable and make sure the pins are correctly screwed in. Power the computer back on and check to see if the OSD lockout message is still being displayed.


Check the manual that came with your computer or monitor and locate the troubleshooting section if you are still receiving the OSD lockout message.
Find the OSD lockout heading and read the method that your particular model uses to remove the lockout.
Attempt generic lockout removal procedures if you no longer have the manual that came with your monitor.

Press and hold the "Menu" button located at the bottom of your monitor for 15 seconds and wait to see if the OSD lockout message disappears.


Press the "Menu" button again if the lockout message remains on the screen.
Use the arrow buttons to navigate through the main menu options.

Highlight the "Settings" or "OSD Menu" option and then hit the Menu key again to access the new list of settings.

Scroll down to the "OSD Lock" heading. Use the arrow keys to change the setting to "No." Hit the Menu key again to return to the main menu. Scroll to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lockout.

hope this helps
