Line of discolouration down side of Cinema Display A1267

It's a line of discolouration. Is it a cable issue?

Probably not a bad cable.
Try a black background. If you see a line that is red then it means red is stuck on. Same for green and blue.
It looks like the line is darker than it's supposed to be. That probably means a component for that pixel line is stuck off.
Try a red background, a green background, a blue background. If any of those show a black line then it means that line is broken (stuck off).

With a white background, my Apple Cinema 30" Display has a yellow line. red+green=yellow, so it means the blue line is stuck off.

The line is invisible on a black background

And what about Red, Green, Blue, White backgrounds?

And what about Red, Green, Blue, White backgrounds?

All of them show up fine, with a darker patch running down the side.

I guess it's not a stuck line then.

You have an LED-backlit (edge lit) TFT active-matrix LCD. There might be a minor issue with the LED back light. Or it might be an artifact of the edge lighting? I have no experience with that display.

My Apple Cinema 30" Display is fully back-lit CCFL.

I'm going to take off the front panel and give it a wipe down, it may just be condensation. I'm not really sure so trying anything could fix it!
