Pink lines in white space, green lines in black space?

"Quick fix for this issue that at least means you can work on your machine

install ""flux"" it changes the colour temperature of your screen and makes the white slightly orange with no pink lines (green is still there)

To get rid of the green in videos - In VLC go to Window > Video Effects.. and turn the contrast down, yes you lose the reason why you bought a mac with a nice screen but at least everything isn't green. (remember to set VLC as your default player for video files)

BE WARNED - I left this for a long time and eventually the cable started dropping the image completely (i.e screen was going black)"

"This issue is almost, 99% of the time, never the cable. The idea that the video cable causes this is a myth that has been perpretrated for years by wishful thinking types because they want a ten dollar fix to their problem. One person says the cable fixed their problem so 100 other people buy an LVDS cable only to realize that wasn't their issue, but since they never come back to the thread to say it was not the issue, no one ever knows... they just assume the $20 fix will work.

Reballing is also BS because the GPU is DEAD!!!! Putting new solder balls on a DEAD GPU does nothing, you are just heating up the dead chip to make it work again, similar to how poking a recently killed bug causes it to move a little until it stops.

Try this if you have a machine with integrated graphics + discrete GPU. boot up, do nothing. Then open photo booth. photo booth turns the integrated GPU off, and discrete GPU on. If you see lines only with photobooth on, discrete GPU is bad. If you see lines only with photobooth off, intel integrated graphics is bad.

Most of the time this issue is screen or GPU related.

If you have an X1600 based iMac or Macbook Pro from 2006-2007, the GPU is probably already dead, or died 3 times already. These are just trash.

If you have a Macbook Pro with GeForce 8600M graphics, it is probably dead already. While not worth fixing, it is at least fixable.

If you have a Macbook Pro with an AMD GPU - it is about to die or has died already. You can replace the chip but it'll die again in a few years, these quad core sandy bridges married to the same heatsink as a junky AMD GPU are trash.

Whether the issue is in the screen, the GPU, the Intel CPU's integrated graphics, the LCD cable, how the LCD cable is plugged in, or the LVDS MUX; this will be specific to YOUR machine. There is no ""oh this worked for him so it'll work for me, too"", there is no shortcut around thinking, analyzing, and diagnosing on your own. Do not buy a cable because it worked for someone else, do not replace a GPU because it worked for someone else. Figure out your own issue based on your own symptoms, none of that wishful thinking crap!"

"I was experiencing the same problem with my mid-2010 15.4-inch Macbook Pro with Nvidia GT330M. I could also toggle the effect on and off by pressing on the palmrest just to the left of the trackpad. I found and fixed the problem 100% and I hope this can help others.

It turns out that the Macbook had had its motherboard removed previously and had been reassembled incorrectly. When the motherboard is removed, the microphone typically stays glued to the case just to the left of the trackpad. When the motherboard is re-inserted, the cylindrical microphone housing does not go back into its hole in the speaker correctly. This can be verified by the fact that the motherboard does not lay flat and is elevated by a few milimeters right where the motherboard screw beside the keyboard ribbon cable is. Typically, users will just tighten this screw thereby forcing the motherboard back down into place. What this does, however, is that it slightly deforms the motherboard since the improperly inserted microphone acts as a fulcrum. It seems that this is enough to stress some solder joint or trace somewhere thereby causing the pink/green screen effect.

The solution? Unglue the microphone from the palmrest area and properly insert it into its nook in the speaker. Either that or don't tighten the motherboard screw beside the keyboard ribbon cable. That is what I did and now the pink (on white) and green (on black) screen artifacts no longer occur.

I'm not saying that this will work in all cases but it did in mine and maybe it will also work for you."

"So i kept poking around for a fix. I may of found it. There are the little round cushions on the logic board going around the fans. The cushions on the left side as you are looking at the logic board from the back of the laptop. Press on them and see if the green pixels disappear. If so use something to keep pressure on them. I used pennies and paper tape. So far so good. Will keep you posted.

Update

Sadly I bought my MBP used and shortly after it started doing this nonsense. I took it to the mac store who sent it out for a so called fix for $325, but it soon started doing the same crap again right after the 3 month warranty. I like most of you can get it to go away by pressing on the right side at the very front of the laptop. Perhaps we all need to start a class action lawsuit. I know for a fact that we all can't be misusing our laptops. There must be a solution. Perhaps with all our heads working on this issue we will come up with one."

dan's right about the reballing. I heard it is labor intensive, requiring skills and tools that aren't easily accessible. I did go to the Apple store and told them that I thought it was the display (when I really figured it was the logic board). They took the laptop from me and I paid a flat fee of $310 (+tax), the invoice said they replaced everything but the harddrive and the fans-point is, I believe you can get your mobo replaced/fixed for the flat fee.
