The only thing I see which looks bad in that photo is the part-number on the 5 pin device. It could be heat damage that has faded it on yours (neither of mine look like that - I didn't take photos of my 2012 one because it looked exactly the same as the 2014 one except the GPS wasn't there).

It's a voltage regulator - low dropout model with 1.5A capability. Looks like it's an adjustable one so I don't know the voltage it's meant to have. I'll have to take my readings again, based on the schematics I downloaded, the only thing mine is doing is accepting the 12v input voltage. The enable pin is telling it not to output the regulated power. I'm almost certain the screen was displaying when I took the readings, so I don't know what it's being used for...

I'll come back with any extra info I can find.
