Screen on the laptop does not come on44?

Moin previously closed my laptop on the YouTube side and now opened it again after about 2 hours but the screen does not come on (wibdows 10) when I click with the mouse or press windows, fn, shift key and b it comes in tone but it just comes no picture what should i do?

Simply restart the tow top or "kill switch" - hold down the power button until it goes out. Sometimes laptops can get confused and get stuck in a loop after switching from full screen to standby. But as I said, a restart usually helps.
