Hi, 5 month ago i have bought this monitor and since yesterday i never connected any input i have only test lcd osd menu' without connect nothing, yesterday i tried to connect my pc but the lcd don't work, i tried also to connect analog input but nothing. The on-screen menu' don't work anymore, i believe that there is a serious problem on my monitor, work only light button on the bottom but lcd don't work.

Do you suggest any idea or test to do?

Do you think that i must ship monitor for assistance?

Thanks to all
