I have the Early 2011 13'' MBP. A few days ago, there would be a purple hue to the display when booting up. The only remedy I could find was closing the lid and reopening it. After doing this step, the purple hue never came back until restart. I brought the laptop to Genius Bar and they stated that they were going to replace the display. I am still covered under Apple Care. Both the laptop and Apple Care were supplied by my school. Today I received a call saying that there was liquid damage to the logic board. The representative stated that it would cost $750 to get repaired. She also said that it wasn't water rather a sticky brown substance. I am not about to drop more than 2/3 the cost of buying it retail to fix this issue that only occurs on boot up. I recall in the past where I opened a shook coke bottle resulting in it exploding. I managed to clean up the liquid immediately right after. No problems has occurred since and this happened more than four months ago. I am going to see the representative today. She stated that it performs as I left it, it still works if the lid closes. I want to know if it is possible to fix this situation by myself. The rep said that removing the back cover does not void warranty, however tampering with the logic board does. I want to know if there is a way to "fix" the problem without tampering with the board. From what I can tell, the problem isn't serious as the computer works fine in every other aspect. I thought of taking a wet cotton swap and cleaning off the soda. Will this work without damaging the logic board or voiding my warranty? EDIT: The liquid seems to have slipped in through the crack where the display meets the base. I do not believe any LSIs were triggered.
