My MacBook Pro display has thin blue vertical line

Question

My MacBook Pro display has thin blue vertical line

Can I do any troubleshooting for my display? I rebooted into diagnostic mode and ran tests - no fault found. How to best troubleshoot this to verify display issue or video and what to do about it? I am in an extremely remote area (Cocos Keeling Islands) and cannot just walk or even drive to a apple store for support. How best to get a replacement device if needed? I have applecare - OS X 10.10.2 MacBook Pro (Retina, 15-inch, Mid 2014) 2.8 GHz Intel Core i7 - 16 GB 1600 MHz DDR3 - Intel Iris Pro 1536 MB

Thanks guys!

MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite (10.10.2), 2.8 GHz Intel Core i7

I'm going to assume your AppleCare is in Australia. Call this support number:

Australia

(61) 1-300-321-456 1

Otherwese find your support number here:

Contact Apple for support and service - Apple Support

" ran tests - no fault found."

Yes that's because it's a problem with the display itself. Mainly the adhesion of the vertical driver array.

If there's no signs of physical damage Apple should replace your display under AppleCare.

Thanks for your feedback.

While talking to apple support I figured we should test with the NVIDIA video card. when we forced use of the NVIDIA card the issue remained, so both cards were tested and the stripe remained. We did a print screen test and the stripe did not show on the screen print. Seems to point to the display or perhaps the connector. so I am sending it in.
