Need the value of a resistor at a given location

Hi all,

I have a late 2012 iMac 27" (661-7156 and 820-3298-A) and it has a video problem, Upon tearing it down, I noticed that a resistor near the LVDS had burned up, so I believe that I found the culprit. Can anyone tell me the value of the resistor so that I can replace it? Much appreciated!

Ryan old question and only answered for completion’s sake. That is reference designator L9500 which is a 250 Ohm ferrite bead (fixed inductor)in a 0603 package.

You will need to check why it blew the way it did. There should only be 12 Volt on that rail, so make sure you have no short anywhere else.
