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

My solution for this problem was to just unscrew the 4 leg screws and the 2 in the botton. Then with a card, such as a creditcard or a swipe card of some sorts just carefully take off the black (or in my case silver) front plate and just take out the circuit board that controls the buttons. Then carefully put back on the frontplate, put the screws back in, and it'll work. The only problem you create is that you don't have a power button anymore, but you can obviously solve that with taking out the power plug.

I had the same problem. looking at the solutions and saw the hair dryer solution. Having had a air compressor close by, I opened the monitor, took out the console button pcb.
Then using compressed air on each of the buttons from all possible angles.
Reassembled everything, and voila... all working perfectly again.

    the compressed air one in #3 gave me an idea. I simply got right up next to the "+" button (the one that seemed to be stuck) and then just took in a deep breath and blew as hard as I could. Instantly fixed it.

Monitor menu screen appears on screen


Try a hard reset: Unplug from power source, disconnect from PC and wait for 10 minutes. Reconnect everything and see if the issue is resolved.
If not, then you either have a loose contact on the menu button or failing circuitry. I'd recommend calling Sharp tech support in this case..
