My late 2013 27" has just developed a screen fault. Its a white outline running round the screen. Any ideas what the fault is and how to repair? Could be a good time to crack open and fit SSD. I have a thunderbolt display attached and tried mirroring the screen to that and there is no problem, so unlikely to be video card, ribbon connector?

The power of MacRumours, as I clicked to post, the screen went back to normal. Strange.
