No backlight but has display. Might've found possible reason

Greetings, this is my first time posting on iFixit and the first time I was able to get a hands on an Apple product such as a Macbook Air A1466. This was given to us by a friend and stated that it was left near the restroom so it might've gotten some water damage.

After receiving the Macbook, I immediately tried to see if there's a display even without the backlight but sure enough there was. I disassembled it and found a corrosion of those small SMD resistors around a small chip.

I tried to clean the corrosion but due to the severity of it, I accidentally tipped two of the small SMDs. I wanted to ask if what part are those and are there specific types for them.

I hope all of the files I uploaded be of help. Thank you very much.
