I've got a Microtek 15" LCD monitor. When I boot up the computer, the monitor starts out normal, but only for a second or two. After which it goes almost black (you can still see the screen, but it is extremely hard). I've tried hooking it up to a different video card and even switched the VGA cable, with no luck. I've also tried the different settings i.e. brightness, contrast, auto-adjust. Does anyone have any suggestions? Is this something that's fixable, or completely dead?
