When I power on my laptop the light blinks but screen is black not show any thing

If you shine a flashlight against the middle of the screen when you power it on, can you see anything? Can you try hooking it up to an external monitor? Do any lights on the laptop seem to be blinking in a pattern? This could potentially be caused by a few things, like a bad display cable, bad screen, or something else in the laptop preventing it from completing its POST (power-on self-test), but we can’t really say what the culprit is yet.
