I'm feeling kinda dumb

I went to the flea market and I bought a 2DS for 10$
I thought the battery died on it
So I bought a charger for it for another 10$
On our way home and when we go into the car
I found out that it DID have some charge in it
And when I turned it on...the screen was HORRIBLY cracked
I couldn't see anything on the top screen and the bottom screen was so glitched out
I couldn't see anything
The sound and the touch screen both still worked though
But I just spent 20$ on something that doesn't even work...

I was thinking about trying to fix the screen myself as like a summer project or something
And even if I messed up I could just sell the parts right?
I don't know... should I try and fix this 2DS or should I just sell it for parts?
What do you guys think?
