This problem seemed to be random, but now it's constant. Whenever the screen is on, the viewfinder glows red. If I remove ther lens I can see that all the RED LED's in the viefinder are illuminated. Screen off - no LED's. This makes it impossible to shoot if the screen is on, say displaying settings, etc. It also makes long exposures impossible if the screen is illininated |(level, etc.) NOT just the focus points. It's a very bright, red glow. If the lens is off, I can actuially read by the glow of the red light.
I have seen more and more people asking about this in various places (Flickr, camera groups, etc.) and nobody seems to know.
Here's an image from the web - this happens every time the screen is on. Shooting video, viewing images, looking at the menu - any time.
I have reset the camera. Tried differenent lenses and no lens. If you search the web it's a fairly common problem. I have changed all the AF settings. You name it. Nothing seems to work. Removed the batteries. No help there. The only soultions I have seen on the web are "I have to return the camera...."

I've had it a year, so it's out of warranty. It's obviously a defect/design flaw. I know 8 people with the 5D MKIII - six of them are now experiencing the same problem!
