Can the HDMI part be replaced?

Yeah, that's what I was expecting. Thanks for your answer.

A separate offtopic question, for my curiosity. The logic board has this "weird" battery connector (in the ifixit guide it is reffered as "the battery connector), it is different from the other rippons and quite stiff. I was wondering, if someone would move it to different angles (let's say repairing the logic board multiple times and moving it up and down (when finished)), would it brake off similar to a metal bracket being bent a lot?

@ciprianflo33831 - Copper is a bit more malleable than aluminum or steel. So while I wouldn’t over do the bend back it should survive a good dozen bends without hardship which is assuming you replaced the battery four times in its life and a few other events.

To be clear here the amount of bend I do is as little as needed and I use a plastic pick to wedge between when I need to do something to the logic board to prevent it getting power.
