2 hours ago, I was using my pc with no problems at all, and then went out of the house for like 2 hours(computer and monitor were both off)and came back turned them on back and I figured out that my screen isnt working! When i turn it on the led flashes as normal, then the backlight turns on for a second and it just sits there on black screen, but led still flashes. Its not up to computer since i cant get anything on monitors screen. What happened?
