White pixel band on my 15" screen

Question

Hello guys!
I hope you can help me because I do not know where to turn now. Let me explain my problem.
I purchased in the month of November 2010 my 15 "MacBook Pro (mid 2010, 2.4 GHz, 4GB of RAM). During the first year of use no problem, the mac worked great and I used it immediately as your primary computer ( traveling and living away from home was an obvious choice.) If at the beginning of the second year were presented serious problems, namely: continuous computer crash, that I initially tried to solve disassembling and exchanging of cards instead of the Ram ), irreversible damage to hard disk drives (internal and external) resulting in loss of critical data, partly recovered by programs such as Drive Genius. And a band of white pixels appeared on the screen (approximately 6.5 cm from the left side of the screen wide and about 4 cm), which is attenuated slightly shake up the screen. All these problems (in time of exams and work) have led me first to ask for help Aesse computer, Apple Premium Reseller of Catania, with whom we have tested the Mac for more than a month, and it was found necessary to replace the Main Board. same fate at the Apple Store in Catania.
After litigation related to Apple's warranty (the problem occurred in the second year and was linked to a lack of conformity), the Mac has been sent by the retailer Euronics (chain reseller Italian electronics) where I bought it, to its headquarters in Turin , where it replaced the Main Board. It's all right for a year.
To be noted that in terms of performance, the Mac is back to the first, but about two weeks the band reappeared pixels, giving me a few problems in the visualization and realization of the work (I'm a graphic designer). The Hardware Test does not detect any problems and the band alternates between moments of everlasting presence in moments of terrifying absence (for example, two days ago I had to present to a client a job with the **** white band, the first five minutes when he was absent ).
I did research on research on the internet but it seems this problem is far from common (the only loser I am, of course). I assume by contradiction that it is a burnt connector on the screen, because when the screen is slightly bent at the sides of the band fades or disappears (sometimes to reappear, sometimes to disappear), but would not explain why after repair (not touching the screen, but only the Main Board), the problem was not resubmitted immediately, but only after a year ... So, not being an expert, I ask you if you can understand what the problem is, because I have run out of options.
Thank you all for your attention

Welcome to Apple Discussions, wannafly.
You should be able to take it to be inspected at an Apple Authorised Service Provider.
