Need help to fix White light of death

Hello everyone,

I need help to fix the wlod on my ps4 pro (nvg-004 Board).

If I connect the ps4 to my tv it shows no signal. But on the source screen I see the Ps4 source flickering.

I checked the port. It’s fine.

I replaced the Panasonic MN864729. The issue is still there.

Any ideas to fix this?

Best regards
