The display ports on my 2070 super black do not work for some reason. I have had the card almost a year, and have not tried to use the ports until i recently bought a Rift S. I got approved for an RMA, but when i took the card out of my PC and was about to pack it up to ship, i noticed:

It seems as though theres some sort of corrosion on the PCB. This card has never taken any falls and it has never have liquid spill on it. What would cause this to happen to the card, and will they still do the RMA when they see this since whatever caused it is out of my control?
 
 

I messaged EVGA showing them this because i want to be completely transparent about the process. I dont want to use alcohol, or touch the PCB in anyway in fear of potentially damaging it more. Will they repair it if they deem that the damage was caused by me?

I was expecting the normal thermal pad oil but that is very different then what I expected to see. Will be interesting to see what EVGA says.

Even though you say it's never had liquid spilled on it, that exactly what it looks like. That looks like some kind of coolant from an AIO dried up around those SMDs. Coolant would also make sense since most of them are non conductive so if they do spill on electronics they won't cause shorts. Definitely get a soft bristle tooth brush and some 90%+ alcohol and clean it off before sending it in. Alcohol won't do anything to damage the card so don't worry about that.
