Why is screen green tinted and flickering?

A couple days ago my screen turned green after a few seconds of booting up. Here are pictures of the same image on my broken MBP and a functioning MBP.

Characteristics:

  • Some parts of screen flicker - different parts flicker depending on image (see end of album for video of textbox flickering on Wikipedia)
  • Screen changes shades of green over time (usual deepens)
  • Images appear normal on external monitor (via firebolt/hdmi)
  • The screen reverted to normal colors for an entire day yesterday, but is back to green today

Assessment from Apple genius bar appointment:

  • It's definitely the motherboard
  • The GPU looks like it's toast
  • ~$500

Assessment from computer repair shop:

  • It appears to be the display
  • ~$350

What I've tried:

Potential solutions

  • Replace display cable (LVDS)
  • Replace LCD
  • Replace entire display
  • Replace motherboard
  • Clean off some other component

I suspect Apple was wrong and this is not a motherboard issue because of normal external monitor behavior and the screen sometimes works.

Does anyone have any insights? Any other solutions? What should I try next?

What does "open the back panel of display" mean? The displays on MacBooks do not have panels.

The back cover of your mac display

To fix mine i updated the OS and installed the latest Adobe flash player. I have not had the issue on youtube or elsewhere since doing this.

Also if this doesnt fix the problem then you may want to reflow the graphics chip

if you use a hairdryer you can reheat the graphics chip on a not too hot temperature and it should work fine.

The screen colorings occur in non-video environments (e.g. just after bootup) so not sure how the Adobe flash player upgrade would help. Also what indicates that the graphics card is messed up?
