Dead Pixels?

The reason is that it's very difficult to get 100% working (even sensors can/will get this problem)

I've never seen or heard of this happening on any LCD screen before and it certanly isn't a commn thing.

Sensors can suffer with dead and/or stuck "pixels" as you say but this has nothing at all to do with the LCD. They're not the same systems, in fact they're not even similar! Failing photodiodes on a sensor occur less often than they used to thanks to better manufacturing techniques. But failing "pixels" in an LCD is not common or acceptable. How many LCD TVs, computer monitors, mobile phones, other camera screens, mp3 players or even cash machines have you seen with this problem??

I would be on the phone to Canon asking for a fix or replacement...

Quite a few to be honest (including the one I'm using now). It's actually pretty common and, as mentioned before, most manufacturers have a dead pixel policy which covers how many dead pixels are required in a 'new' monitor before they'll consider replacing it.

Nice one! Not seen this list of manufacturers and their policies - very useful for those that get dead/stuck pixels! Cheers!

No worries.

And FWIW Canon's dead pixel policy for their camera LCDs is to tell you to ignore it.
