    green flickering display on Macbook Pro 15"
    my 2009 Macbook pro 15" has just started displaying bright green pixels flickering wherever there's a dark area on screen, particularly in photos. I've seen the issue being posted elsewhere, but no resolutions. It's been suggested it's the graphics card and when i press down hard directly to the left of the "tab" key the flickering green goes away... Can anyone help?? thanks

    I have a video but not sure how to post here....

    Display "flickering" can be a possible bad or fraying display cable.

    Thank you Nick... is this something that is fixable relatively easily?

    Firstly...the bad video cable I mentioned is just a possibility. The only way to know for sure is to replace the cable...and see if things are corrected.

    Second...who's going to do the work...you or a professional? I'm asking since the cost to fix this may be a lot more than you think...and could be a good proportion of a 2009 MacBook Pro's value. Repairing computers can be expensive...and on older computers...it's better if the owner can do their own repairs.

    I would have to get someone else to repair it... which somewhat complicates things unless this is a relatively easy fix.... 1) I'm in Belize, which does not have any apple repair centers 2) i'd have to order parts from the US for someone to bring down

    re the cost... this computer was given to me so it actually cost me nothing.... so i don't mind spending on a fix... it'll be cheaper than buying a new computer here in Belize, macs are in any case not available here.

    If the fix is something that a (non mac) repair person could do can you let me know?

    many thanks I do appreciate your help!

    "Relative" is a relative term. What one person thinks is easy...another person will find hard. Let's put it this way. If you've never opened up a laptop computer before...then this repair will be harder for a first-timer than for someone who has done it 100x.

    Aah...you're at least our 2nd member from Belize!

    Go to this website:

    iFixit: The free repair manual

    Look up the repair procedure that most closely matches what you need to do (replace the video/display cable). Then see if you can do it. Of course remember you're going to need some tools!

    Yes...this is a repair a non-Mac repair person could do. But I'm sure they're going to complain a lot about working on a Mac. And will probably want to charge you more...just because.

    Finally...again. It may or may not be the video cable. From what you describe...it could be the video cable. But then it could also be the video hardware. And if it's the video hardware...then the computer will need a replacement logic board (EXPENSIVE)!
    performed

    The video cable is simply a MUCH less expensive repair...and a repair that can be by a user.

    Ahh...that's very fortunate! I've been to Belize...but just did the typical "tourist stuff".

    I was going to mention this as a possibility...if the problem wasn't too bad or was too difficult to get repaired.

    I have the same problem, and when I push on the body next to the TAB the green flickering goes away. Do you know, how i can resolve this permanently?

    Try opening it up and reseating the video cables. Make sure they're tight and seated snugly to the connectors. If that doesn't cure it, then you probably need to replace the cable(s).

    I cant check the connection on the screen end of the cable (I don't have that funky star shaped screwdriver to take the screen off), but I have re-seated the one on the logic board. Seemed to help until I closed laptop and used it the next time. same puke green crap. I checked the cable again, seems fine. I guess ill have to take it to a repair shop. damn.

    You could purchase an inexpensive mini-screwdriver set which includes the screwdriver you're missing. An inexpensive thing to do before taking it to the shop.
