Problem sa monitorom

Pozzz,
Znači problem je takav, da oni dugmići koji se nalaze sa zadnje strane monitora (što se podešava osvijetljenje i te zezancije) nemaju funkcije. Kad pritisnem bilo koje (ima ih 4) samo mi se na monitoru pojavi natpis OSD LOCKED.
MOLIM POMOĆ
Hvala

On screen display is locked. Fix it by:

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.

Hvala puno problem riješen
