Problem in TFT

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.

• If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
• If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.

Hold the menu/ok button for ten seconds, to unlock the OSD.
If this doesn't solve the problem, then it's probably the button that got stuck.

There are two things you can do to repair it, but both require that you dismantle the casing, which voids any warranty.. so, if the monitor's still covered by the warranty, or if money is not an issue, have it repaired by professionals on an accredited brand shop (check your warranty details for more information on this subject).

If not, remove the casing, locate the menu button's contact switch on the circuit board, and try to release it using something thin like a screwdriver, x-acto knife, or set of plyers.
If this doesn't work, chances are the menu button is stuck on a loop, sending a continuous signal to the board (which keeps locking/unlocking the OSD).

If so, your only solution (other than take it to a repair shop) is to remove it, by prying it off with a screwdriver or set of plyers.
Of course, you'll lose access to the OSD features, but I guess this is better than to have a message stuck on front of your screen all the time..

This is a tried and working solution, since I had this problem myself (with a Philips 190B monitor), and solved it successfully, with this method.
