My crt menu keeps popping up and so does the button that reduces things. This is annoying because the button with the minus sign is for the contrast and it decreases the contrast to 0. So before i send it to a repair shop and get ripped off i wanna make sure that there's no water or other liquid or something else causing the problem, if i send it directly to the repair shop the guy without checking will sax that board will need to be replaced and charge heavily, this is india for you. So i wanted to know is it safe to spray rubbing alcohol on the buttons and/or dry with a hair drier or should i just send it for repair? I don't wan't to buy a new monitor right now as i already bought new stuff and am low on cash. Please help. Don't want to further damage my monitor as well.
