Got this dead Unifi US-16-150W, assuming it was the power supply. Alas the PSU and everything looks perfect and the PSU is outputting a solid 53V.
I noticed that upon disconnecting then reconnecting the 4-pin connector from the PSU to the switch's mainboard it makes quite a spark. More than I would expect. So I got curious, took the mainboard out, and found the bottom to be like this.
Is this water damage? Or something else? Should I try to clean it off? Or is it toast?
