PS4 Pro, posts in 480p but no image?

So a short back story.

Customer brought in his PS4 pro because his cousin attempted to repair the hdmi report and failed and did more damage but we managed to fix most of it and got it working and posting again however… its only doing 480p and showing no image at all… it does load up into the home screen but got no sound.

Controllers do sync to it, it does white light and if i click on the account “blindly” i get unsupported format.

So, we changed the encoder IC thinking it was possibly bad but the issue remains.

Hoping to find some more information on what i can try next.
