Hey guys.
I accidentally spilled some water on my Macbook Pro, when I turned on the Mac a few days later the backlight suddenly stopped working.
I have a early 2011 Macbook Pro 15,4" with a 820-2915-B logic board, I red that the backlight fuse is the main cause of the problem so I bought a multimeter to check the fuse for continuity. Since I'm new to using a multimeter device I don't know what readings I should get if the fuse is blown, therefore tested them all so maybe you could see if the fuse is OK/blown, this is what I got:
At 20Ω = 1
At 2000Ω = 1297 before it instantly dropped to 1
At 20kΩ = 10,99 for a couple of sec then back to 1
At 200kΩ = 155,0 and increasing
At 20MΩ = 3,45 and from here it decreases really slow...
I'm pretty sure it's already blown but doesn't hurt asking some professionals.
Now to the other problem, I don't which size of the SMD fuse I should buy, at macrumors a lot of people says 0402 and some says 0603, pretty confusing.
I uploaded a picture for you to see, it's the fuse with a "P" on it.
Hope this information was to any good.
Thanks in advance
