I have a gateway desktop that I bought new in 2006. IT came with a 19″ LCD monitor that started shutting itself off a few weeks ago after about an hour of use. The intervals between turning itself off has now been reduced to one second. When I turn it on, the screen is lights up and then immediately fades away. The video card is integrated into the motherboard so a loose card was not the problem. I attached a different monitor to the computer and it’s working just fine. That tells me that the problem is in the monitor itself. I took the monitor apart and blew air through every vent hole I could find. No difference. Any ideas or is time to purchase a new monitor..??
