Hdmi issues after replacing and testing all chips and port!

hey guys just wanted to check in and see if anyone might be able to lend me some brain power.
i have an xbox series S ive been repairing it started as “no power”, got power going and now there is no signal(i dont know if it worked before hand).

i replaced the HDMI port, nothing,
i replaced both hdmi chips, nothing,
i checked all caps and fuses around the chips and hdmi port and no shorts,
i replaced a few of the caps and fuses because they looked a bit charred still no shorts.

Is there another component i should be looking at aside from the 2 chips, port and caps/ fuses?

any advise would be spectacular, thank you all
