I own a brand new unibody MacBook Pro 17 inch with maximum configuration (8 MB RAM, fastest CPU, 256 GB SSD, 10.5.6., latest software updates) delivered to me on March 4th. I am not a heavy user and just used it for Word processing and the like over the last days. Until this morning everything was fine - except a few cases during which my large Cinema Display shortly turned black (for less than a second) and turned on again, which was not a major issue for me. Today, while on a business trip and not using an external Display, I noticed a strange, not too loud, sound from the left upper corner of the notebooks casing (right above the left speaker). It sounded like a slightly imbalanced fan making vibrations at low frequency (like a fan blade repeatedly hitting some small object). Not loud but noticeable and different from before when due to the SSD the MBP was absolutely silent. The problem does not depend on CPU load. I just let the machine do a photo mosaic to increase CPU utilization. It appears another fan went on after some minutes to cool the notebook. It went noisier, which was not unexcpected. I just switched it off after 2 hours of working like this during which I noticed that the temperature of the upper left corner of the MBP slightly rose (but not to any temperature I would consider unusual for a Notbook casing; my old MBP was much hotter). After turning it on another 6 hours later I noticed that the sound was still there but a new problem appeared. All areas, that were supposed to be bright white (such as the text box in the web form on the MacRumors page I am currently entering this text in) appear not white but with a pattern of alternating white and cyan stripes. This is the case for OS X as well as Windows programs I run in Parallels. It even appears in the password field on the login screen. I also notice a white/cyan flickering of certain areas of the screen. The white/cyan issue is independent of which graphics processor I use (long battery life or high performance setting). And a PRAM refresh does not solve it. -- While writing this I just gently pressed (applying maybe 2 kilograms) on the upper left corner of the MBP casing (right above the left speaker, next to the power inlet). The cyan lines disappeared. But I still have the noise issue. From outside I can not see any physical damage at the MBP. Maybe something is loose in there. I had the MBP in the overhead compartment of a long haul flight cabin, but protected inside a protection sleeve inside a solid suitcase. It may have suffered some minor shocks but nothing too severe and nothing other notebooks of mine haven't suffered before. Anybody suffers or suffered from a similar problem before? What is the best way to fix it? How long would that take? I am travelling around the world more the less permanently and do not like to miss my MBP for too long?
