Trying to FIX 2 Faulty SEGA Game Gears - PART 2

Hi, this is PART 2 of a 2 Part video.
This trying to fix' video shows me attempting to fix 2 SEGA Game Gears that I bought from eBay. Both of them were sold as faulty.
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.
