Purple vertical lines on '12 MBP screen

[archille]

Hi everyone,

I bought a used 2012 MBP 15". I have been using this for 3 weeks and this vertical line shows up. I am looking for opinions from you about this. Is this a LCD screen issue or video card problem?

Thanks guys

... Is this a LCD screen issue or video card problem?
...

Yes. Could be one of those (or both).
Be sure to try reseating the LVDS (video) ribbon cable on the logic board.

Is yours a retina model, or the non-retina 2012 MBPro?
If non-retina, you can try reseating the RAM sticks.

And, you could try an external display. If that works normally, and the other plugs or reseats don't help, then likely it's the LCD panel.
If the external has a similar issue, that should indicate the graphics chip. That's not replaceable, so you would need to replace the logic board to fix that issue.

Thanks DeltaMac.
Mine is is the non retina variant. Now I notice it would disappear for a few minutes then it will come back again. i will do what you suggest in the morning.

I had this exact same issue. Went to the an AppleStore. They offered to replace the screen and logic board for 1k. I thankfully refused. The seller of your MBP probably knew about it too. I had it disappear and reappear as well. Sometimes it went away for weeks and then it came back. You purchased faulty hardware.

You could ask at an Apple store, or other Apple service provider. Your issue may fall under this program.

Did you have it fixed by a third party? If so, was it the logic board or the LCD screen or both?

You may have a Late 2011, and not a 2012 version. The 2011 was dropped from that repair program at the end of 2016.
Quickest way to make sure about which one you have is to view the Model Identifier, which is in your System Information/Hardware Overview.
2011 is MacBookPro8,2
2012 is MacBookPro9,1

ok i had to check again my MBP, i have the 9,1. I follow your link to check the support coverage and had this:

That tool simply tells you that you are outside of the normal warranty coverage.
The program mentioned at the video issues support page MIGHT still apply to your MBPro.
Best way to discover for sure is to call AppleCare, and let them tell you at that time that you are no longer included in that video issues repair program.

Thanks for thought.
I certainly like to have more options to pursue. I’ll get to it next week for now happy thanksgiving!

I fixed it myself... well kind of

it's a interesting solution.

I have replace the dvd drive with a HDD drive and took time to tighten the screws and connection. So far its been working fine (cross fingers).

My paranoid self is still looking to get a spare screen and a logic board.

it's a interesting solution.

I replaced the panel itself (not the whole top case) for ~50. my solution might not be for everyone. but I truly love my laptop, because it's... well... mine and no one in their right mind would want a laptop like that
I didn't want to spend the cash on a used top case because a) they are really hard to find (matte screens w/ higher res) and b) they are overpriced. there is no way I'm going to drop another 3-500 bucks on this laptop. but as long as it works, I'm happy

So it ended up being a display issue after all..... You replaced the display with a lower resolution one?
