    Ik have the same problem and the buttons are not stuk, could it be dust inside the monitor?
    Maybe some foam cleaner (anti static) would help?!

    Is there anyone who has another solution?

The brightness menu screen is stuck on!


Please try to turn the monitor off. Hold down the Menu button while the monitor is turned off, then press the Power button again to turn the monitor back on. This should unlock your OSD menu from your screen. regards

On screen controls have a mind of their own


The buttons are stuck - If the screen is out of warranty then i would take it apart and see if he buttons can be unplugged or cleaned up.

If in warranty Samsung is excellent with repair service. - Depending on the model LCD its either 1 or 3 years warranty.
