Trying to FIX The Retro Future's £24 Nintendo Switch

The Retro Future's original £24 ($30) Nintendo Switch video -    • £24 Nintendo Switch! - Can I Fix It?  
Hi, in this video I attempt to fix The Retro Future's Nintendo Switch. Elliot bought it from eBay and it unfortunately it had severe water damage. After cleaning it and removing the corrosion it still didn't work, so he asked me if I wanted to 'try' and get it working. I was amazed that he managed to get a Nintendo Switch so cheaply so I was very happy to give it a go.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince.
