, my Samsung Tab S3 screen went black please help:

Hey,

So, a few years back I snagged a used Samsung Tab S3. She ran like a charm for about five months—surfing, streaming, all that jazz. But then, out of the blue, these weird spots started showing up on the screen.

I brushed it off at first, figured it was a software glitch. But two months later, boom—the screen went completely black. The only buttons that still light up are the ones next to the home button. It's like a total blackout.

Any ideas what could've caused this sudden screen death? I'm pretty bummed since I was really loving this tablet. Any tips or suggestions on what to do next would be greatly appreciated!! Note, I'm pretty sure that I didn't drop it before.
