They are diodes, not fuses.

Did you test these with a continuity test using a DMM? If so, they would show as open circuit...

Those are MELF diodes. Why do you think they are bad?

The hdmi ports stopped working one at a time. One of those diodes looked like it could be burnt. If it doesnt read continuity showing the circuit is open that would mean theyre bad right?

Firstly, you made two threads of the same topic and are updating both of them. Thus, I will only follow the thread in the repair forum.

Thread found here: https://www.eevblog.com/forum/repair/circuit-repair/
