I Fixed This GBA SP That Wouldn't Turn On - Gameboy Advance SP Repair

I bought this GBA SP on eBay for parts or repair. It didn't turn on when I bought it! Luckily after some quick troubleshooting and a in depth cleaning I was able to get it up and running again. If you would like to see more restorations, please let me know. I sold this Gameboy to a friend, but if I were to fix more, I would be able to sell them or host giveaways. If that is something you think I should do, please let me know in the comments.
