Here's my situation: I bought my white Macbook December 2006. In July of 2007 I let a friend borrow my Macbook while we were living in Japan. The screen began flickering shortly after so I took the Mac to the Apple store back home here in California. Upon receiving the Macbook back I was told they discovered soda inside of the Macbook on the side where all the connectors are at; very close to the Magsafe. They were cool enough to still replace my keyboard which had a crack on it, since they considered that to be a cosmetic issue so i'm still under AppleCare warranty there. Ever since that summer of 2007 I've taken my Macbook in for a keyboard replacement about 3 times. They say it's all good since the soda spill doesn't affect it in any way. But as for my screen flickering, it MIGHT be caused by the soda spill and because of it, my warranty is voided there. They charge $800 for them to replace and repair my entire Macbook they say, from a screen replacement, soda removal and change of parts...etc, but $800 is too much. Even with AppleCare! So I haven't done anything about it. Last time I took my Mac to the Apple Store was a few months ago, but remember being told that if I take my Macbook to an authorized Apple Reseller/Repair place and if they got rid of the soda spill and determined if the soda was indeed the cause or not, my appleCare warranty would be un-voided and i'd be set....but even taking it to one of these guys could be costly for a college student. The reason I ask today is cause the screen still flickers but the whole image at any given time will shake. Literally the image will twitch like it's having a seizure. Nevertheless, I'm a little lost on what I can do. This is where I ask for advice. Thanks!
