I Bought a FAULTY Mini Game Box THING on eBay | Can I FIX It?

With a very clear desciption of "it doesn't work", this Extreme Mini Game Box Emulation type thing is surely an easy fix?
It doesn't appear to display anything and it's unclear if it powers on or not. This one is going to be fun.
Hope you enjoy!
Steve
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.
