Trying to FIX: DELL 1440p WQHD Computer Monitor

Hi, this video shows me attempting to fix a Dell 27" PC Monitor, the model number U2713HM. It will not power up and has no stand by light. The display shows nothing at all, just a blank screen.
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.
