I have a US Logic 17" LCD monitor and after being plugged in and running for a while it may flicker and then just turn to a black screen. And also if it is working ok I may turn the monitor off for a while and turn it back on and nothing but a black screen. It will flicker "vga in" for a brief second when turning the power button on. I have tried the monitor on different computers and same thing. Could it be the power supply not supplying enough power or just internal? Any help will be greatly appreciated. Thanks!
