MacBook Pro Pink Vertical Lines on White Background

Hi Tesserax,

I've had my mid-2010 15" MBP since 2011 and it's still going strong! Unfortunately it fell out of my car, thankfully while still in the laptop case, and when I booted it up, I saw pink static on any part of the screen that was a certain shade of white. I also saw pink and green static during boot up.

The fix that worked for me was to remove and plug in the LVDS cable that connects the LCD display to the logic board. This video provides a good guide for opening your MBP and unplugging the cable: 2010 Macbook Pro 15" A1286 LCD Assembly Replacement - YouTube

Good luck, hope that helps!

Same problem with my 2010 MBP on High Sierra 10.13.2. I would press or twist the laptop in random places and the pink lines would go away only to come back in no time. I replaced the RAM. No difference. I tried this after reading dendowling’s post about using the Dimmer app to work around the problem. Open Safari to a page with lots of pink. OPEN System Preferences : Displays : Color : Calibrate : Continue. UNCHECK Use native white point. MOVE the slider to eliminate the pink lines. I set mine to about 7400. No more problem - for now!

You may get some extra use via gfxCardStatus if you force intel graphics https://gfx.io/

I'd use that time to ensure it is backed up & look for an alternative.

Personally I'd get rid of that MacBook Pro.

The 6,2 was plagued by GPU panics. The GPU was apparently held on with unicorn tears & Apple has ran out it's supply of those. Parts are no longer made for this Macs, repairs are mostly done using parts form other dead MacBook Pros that had the same issues.

Apple has given up on it's repair program…

Third party companies may offer repairs but many of the smarter companies will have stopped touching this model - it can fail again months later.

Search if you need even more conformation… 'MacBookPro6,2 panic site:discussions.apple.com'

Perhaps someone can tell you it isn't a black hole to sync money into, that is not the impression I get.

A second hand Mac that is a different model appears to be a better option to me (it's probably a logic board replacement).

I installed a replacement logic board in my 2006 MBP a couple of years ago from Powerbookmedic.com, which still works today. I would check with them and iFixit.com and see if they have replacements and how much they cost. Installing a new logic board is a bit tedious but it can be done if one has basic mechanical aptitude.

Another option is if you have decided that the MBP is ready to go to laptop heaven, consider a 'reflow'. It is high risk because I tried it but botched it as a result of overlooking some essential details. Do your homework by searching the Internet thoroughly and you may get the Mac working with little financial expenditure. It can be successful and there are outfits that will do it for you, but not gratis.

Ciao.

I have the same problem on Mid 2010 MBP. One work-around is to get a little screen dimmer app which can make the pink lines disappear. You can turn up the normal screen brightness all the way with your keyboard. But, use the dimmer app to cut brightness only about 5-10% to hide pink lines yet, the display can still be pretty bright.

The pink lines seem to only appear on the pixels that are 100% RGB white. I think normal keyboard brightness alters the backlight levels which don't affect RGB. And, the dimmer apps are kind of graying out the RGB so there is no longer any 100% white pixels which makes the pink lines disappear.

I got the app "Dimmer" on app store which is cool because it can do separate dim levels for Macbook screen and external screen.

Side note: I previously had a non-retina display which showed green lines. I had an accident and cracked the screen so, I bought a retina display to replace it. The new retina screen shows pink lines. So FYI, a new display and video connector don't fix the problem, must be a graphics card problem.

Lines or patterns on the display can also be a window into faulty RAM memory that is holding the screen buffer.

If you can capture the defect in a screen shot, the display buffer is bad. If you can not capture the defect in a screen shot, it's the display Hardware that is the source of the artifacts.
