So it's best practice to pull it and go one by one.

Your video definitely shows bad caps around the vertical IC. You have that telltale vertical linearity issue where the scan lines unravel towards the top of the raster
Also in the power supply, vertical has a dedicated feed line from the FBT, with 2 caps on it, 25v line I think, I have never seen a TV do what this does before, start with no V sweep at all, then expand to full screen after 40 seconds or so,
