Hi all, I have a mid 2010 era MBP 15" with 2.66GHz i7 processor. Since January this year (2015), I've been experiencing a problem with the screen, where the black pixels are being displayed as green. See attached photo. The problem does not carry over to external displays, so I'm assuming that it's a hardware issue. What's odd is, the problem disappears when I push down on the laptop body, just to the top left corner of the trackpad, or if I push up on the same area from the underside. Some people have suggested it being a cable issue but I've opened it up, cleaned all of the connections but to no avail. I've come across quite a few similar cases online but no-one has provided a reason for why this is happening and more importantly, a solution to the problem. If anyone could give any insight with regards to causes, solutions, repair costs, etc., I'd greatly appreciate your input. On a side note, one of the reasons that I adore my MBP so much is because of it's performance, which hasn't degraded one bit since the day I took it out of it's box. However, over the past four weeks, it has become painfully sluggish, freezing all the time on minute tasks such as opening or closing apps. I'm guessing that it must be some sort of virus and that a simple wipe and re-installation of the OS should clear it up but I'm just curious to know if anyone else who has experienced the screen issue has experienced this phenomenon as well? Thanks in advance.
