"FIX!!! - Remove the back cover, upper right corner you'll see the cable wrapped in black paper from the monitor connected to the board. there is a tab wrapped to a mini steel bar, pull up on it unlocking it. Pull back on the cable disconnecting it. Spray the area with air to remove dust/debris. Reconnect the cable. Reinstall the backplate. Turn on, and see no more green where black should be.

(My guess is that the dust buildup is semi conductive and 'shorting out' some of the pins/connectors.)"
"Hi everyone, I had the same problem, I solved this way: as you can see from the image, pressing at that point the problem disappeared, so I inserted a piece of rubber (normal rubber to erase) of 4 mm (thickness) so that closing the rear cover would remain as thick. I solved the problem definitely.
Ciao a tutti, avevo lo stesso problema, ho risolto in questo modo: come potete notare dall'immagine, premendo in quel punto il problema spariva, quindi, ho inserito un pezzo di gomma di 4 mm di spessore (una normale gomma per cancellare) in modo che chiudendo il coperchio posteriore rimanesse come spessore ed ho risolto il problema definitivamente."
Hi I have the same problem, I took my 17 inch macbook pro 2009 to a local solutions inc store (apple experts) they diagnosed that a replacement display was required at a cost of £600+. I said no thanks and took the macbook home for further investigation. if i plugged the macbook into my iMac and used that as a display no green lines, so I deduced the same as the shop. I bought a new display from Germany at a cost of £85, I replaced the display, turned it on, only the find the the green lines were still there! Next I will replace the display cable...unless anyone else can suggest what could be the problem?
"I just had this problem. For me it was not the screen connection in the main body of the computer but the connection in the ""screen part"" where the MacBook Pro logo is that came loose over time (I guess from opening and closing). Quick fix for me was I opened screen all the way till I couldn't any more the shut it, did this a few times and viola no more green :) later on I opened up the screen and fixed it properly, the connector had wiggled is way a fair bit out so this would be what I would recommend if the easier (main computer body connection) looks good. You can find info online in regards of how to take apart the screen. I am in no way an expert, I am just telling you what worked for me. Attempt at own risk.
"I'm experiencing the same problem. I replaced my monitor and the green lines disappeared but were replaced by purple vertical lines all over the screen. Again, they go away when pressure (very small) is applied to the bottom casing (from bottom, just above the trackpad in a MBP 2009)
