REVISIT : PS4 Slim Faulty Power Supply ADP-160ER

WARNING: Working on Power Supplies is very dangerous due to the high voltage present. Even when unplugged from the mains electricity, high voltages can remain in the capacitors. In this video the mains electric is NOT connected to the power supply and the capacitors have been completely discharged.
Hi, this video is a revisit video from Week 3 of the 2019 eBay Repair Challenge. The PS4 (PlayStation 4) needed a new power supply because I couldn't narrow down the fault on this one. It was bugging me as I couldn't work out the faulty component. Also a lot of viewers asked for a revisit, and more importantly a lot of viewers gave me advice on what the problem might be. So here it is, let's see if we can find the problem of the power surge damaged PS4 power supply.

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.
