Xbox no picture

My Xbox one x has no picture.
HDMI Port Looks Fine with no damage.
My question is what could be Borken and how can i Check this ps i dont See any optical damage.

The Retimer ic TDP-158 is common for failing on One Xs, which results in only low resulution or no HDMI-output.

Is there a way to check this or simply renew it?

You can check surounding caps for shorts and four dataline pairs for identical resistance (in and out).
If you checked the HDMI port for loose pins and both filter rows towards the HDMI for continuity and no crossing from one line to another, I would replace TDP-158.
