Help me fix my 2008 a1286 logic board (pics included)

[russthechamp]

So I picked up a used late 2008 macbook pro off ebay, and the owner reported the wifi wasn't working. After inspecting the logic board I found the following burned out area next to the airport connector.

I was hoping I could replace these components to see if I could get it up and running. Does anyone know what components are missing, and where I might be able to get replacements?? Any advice would be appreciated.

Thanks
Russ

see whats missing

Looks like a little surface mounted resistor (PITA to replace).

0.5 ohms?

Were you able to figure out what that resistor value was? I had the same thing happen to me after replacing my display. The ohmmeter is reading 0.5 ohms on the identical layout just above it (the parallel resistor and capacitor) which doesn't seem likely.

Hey there. So i had the exact same issue as you. I posted on ifixit.com and someone identified the part for me. I replaced it (somewhat difficult to do). Here's a link: http://www.ifixit.com/Answers/View/...itor-resistor+that+shorted+out+on+logic+board

The part is available here:

Hope this message isn't too late. Best of luck
