"Why Samsung galaxy tab a 10.1 2016 goes black some time"に関する回答Our son's Tab A 10.1 (2016 ed) went black screen on us after a short fall: I could track its position with Device Manager, it made sounds when triggered, but otherwise nothing showed on screen. No variant of rebooting fixed the problem. It took me a few tries, but I managed to A) Turn it off (Vol- and Power pressed while plugged in) and got no fix in Device Manager. Great, at least it's off before rummaging around inside it. B) Get the cover off following ifixit instructions (though it was tighter than implied, and actually took me the best part of an hour, for fear of breaking the screen).

One of the ZIF connectors must have been shaken loose, even though the tablet has a thick foam protector.
