I recently purchased another Canon 5D Mark II, brand new. I've only used it for about two weeks and something worrying appeared on my LCD screen display whilst out shooting today.

Several green pixels, they look to be defective or 'always on' as usually described have appeared very central to the LCD display. Never seen this before on a DSLR. The images / movies don't appear to be affected at all.

However, it's very distracting and I don't think I could live with it. Makes it hard to focus sometimes as I have to move the camera if my focus point lies near these defective pixels. Wouldn't mind so much if it were one or two, but I can count at least 41 LCD pixels affected in total.

Anyone seen anything like this before, or know a fix?

Send it back to Canon for service under warranty. Same thing happened with my T2i. Turnaround was about 2 weeks which I thought was pretty good.
It can all be initiated on their website too and is trackable.

Did you use any wiewfinder on the camera?

Ivan,

Yes I do, I use the z-finder pro 3 from Zacuto... I know what you're thinking, but I've only just started using it and I'm extra careful to make sure the sun doesn't get in there. The camera is only a few weeks old in any case.

Does it look like sun damage?

Yes - it looks definitelly like a thermal damage of the polariser - but i am of course not 100% sure.
Just look by the camera of if you don`t see any machanical changes. Its hard to see with the plastic glasscover on - but its possible.
