Are the connectors corroded?

15" MacBook Pro (mid 2010) reports no airport card installed. I opened up the unit and noticed this.

Shouldn't the connectors be gold? Does this mean water breached the case and the connectors are corroded? The card suffered the same fate?

Does anyone have a video on how to replace the entire antenna assembly?

Yes, that looks like corrosion from exposure to liquid.

Before replacing anything, I would try and clean the corroded areas with pure isopropyl alcohol.
