I watched your video and I cleaned the fan up under the power supply and made sure everything was put how it suppose to be and all I get is the game turn on then off
My boyfriend had the same problem 6 days ago and it turned out to be the thermal paste. So I suggest checking and replacing the thermal paste to see if maybe you wiped it off and didn’t replace it or if it just needs replacing in general. Also check out thermal paste replacing videos. It seems like the issue that you are having is that the ps4 thinks it is over heating so it’s an automatic shut off. Replacing the thermal paste should fix the issue if everything else is cleaned properly. I’m replying because we got the thermal paste today and replacing it worked hope this helps
