Retro | Game Boy: Kaputtes Display, verkratztes Gehäuse - Reparatur

What a great time the 90s have been? After classics like the C64, Amiga or NES a little Company called Nintendo decided in 1990 to release a tiny little portable gaming device: The Game Boy. I was a little child at that time and wanted one desperately. My Game Boy doesn't exist anymore. But nowadays it's easy to get one from the Internet for little money. I got one for 37,- Euro, but it has seen better times. The display doesn't work properly and it's body is nasty and badly scratched. Can I repair it?
