Trying to FIX : Faulty Apple Keyboard Model A1243 purchased on eBay

Hi, this 'trying to fix' video shows me attempting to fix a faulty Apple keyboard purchased from eBay. The fault is that the majority of the keys are not working,
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.
