GAME BOY Color | No DISPLAY and No SOUND | Can I FIX It?

I'm trying to fix this beautifully green Nintendo Game Boy Colour bought faulty from eBay! It doesn't have a display or make any noise. What's going on there then!?
Hope you enjoy!

PS. I'm not an expert in repairs at all. I do this for fun, and it may not be the best or safest way to go about repairing broken stuff. I'm pretty good at melting plastic though. Please don't copy me - I'm an idiot.
