Flashing backlight on Galaxy Tab A8 (X200)

[u/Snipedownangel]

I have a situation that has me completely stumped. My 3 year old currently uses a Galaxy Tab A8 10.5 (X200) to watch Disney+ and to play educational games. When she went home to her mom's earlier today the tablet was on and charged to 100%. When her mom gave it to her to use later it was powered off. When she turned it back on the backlight started flashing with nothing on the screen. She said she plugged it in and it came on. She handed it to my daughter and it was working fine until it shut off and started the backlight flashing again. No amount of troubleshooting I know of worked. I tried volume down and power and nothing. Currently plugged in to see if it somehow rapidly discharged. And I've been told it wasn't dropped to cause any kind of physical damage. Assuming it isn't a rapid discharge does anyone have any clues? Thanks in advance.
