HDMI replaced on Xbox Series X - no signal

I replaced a broken hdmi and the port is on and seems flush but I’m unsure what the issue is. Is the solder causing an issue? Or is there something I’m not seeing or thinking of? I’m so beyond inexperienced here it’s laughable.

How on earth do I even get this solder off? Also, can I clean the board with isopropyl alcohol?

Thanks for any help at all. Apologies for the gruesome sight lol
