In over my head, black screen

Hey all. I got RP2S and it's been finnicky since I got it. It's currently black screened and not turning on. Before, it was playing for a little while and then going black. When it would go black I could hold power and get it to vibrate like it was turning on, but the screen wouldn't.

I did follow through with the battery troubleshoot I've seen with black screening. I let it die, and full charged it on trickle. It turned on once, then when it went black, it's just off now. PC isn't reading it or anything.

I didn't install any software or update anything, I just popped it on and was playing the games it came with.

Any tips?
