I may have broken my 3ds and I don't know what to do
So a couple months ago, I had a hellish fever. The kind that makes you move in slow motion while the world speeds up around you. I went to my local store and got some soup and a frozen minute maid orangeaid. When I got home, I totally forgot about the orangeaid and I went to sleep. The next day, I opened my bag and everything was soaked in goop, including my New 3ds.
The battery was swollen and the shoulder buttons were gunky. Since then I have dismantled it and cleaned the board with rubbing alcohol and bought a new battery (shoulder buttons are still gummy). It won't turn on, and the charging light would do the thing where it turns off after a few seconds, but I have since got it to stay on. I let it charge for hours and it still wouldn't turn on. I even double checked all the ribbon cables. If anyone has any advice, I'd appreciate it. I'm kinda broke right now, so if it is the motherboard I'm kinda screwed. Thank you for reading my post.
