PS4 Pro screen of death upon game launch

Hi there, I’ve uploaded a YouTube short of the issue.
I’ve changed hdmi ports across TV, changed output settings from all the way from the top to lowest. In lowest it loads maybe a sec longer and then dies. Changed hdmi cables, took it apart and have redone gpu paste, fan was replaced last year and works perfectly well.

Please see below, any insight is greatly appreciated.
