2DS wont turn on, makes a pop noise

I just bought this 2ds in fb marketplace for like 65 bucks (pretty cheap) with 2 problems, the camera wasnt working and the volume button also didnt work, not a big deal
but when testing it, i opened the camera, the console froze and died, since then it didnt boot
so i opened it to see what happened, found the camera broken and removed it, since then it makes like a pop noise trying to boot, i changed the battery but didnt solved the issue
any ideas? its been years since i had a ds
