No image from the screen

@kingmalus please clarify what you mean by this "the screen mirror is not block". Next connect an external monitor to your computer and see if that displays correctly. If it does, you know it is your LCD. If it does not, the issue will be with the GPU on your motherboard. Let us know what you find out.

Hey, that sucks! If your screen’s black but the computer’s on, try turning it off completely and then back on. Sometimes it just needs a quick restart. Also, check if the brightness accidentally got turned all the way down.
