Working in Live View  When I press the zoom button to focus I get a white screen with a 5x or a 10x written.  I don't get the zoom picture.  It just started doing this today and I've been using it for years.  Any help?  Thank you.  OH   I have a 450D  (rebel xsi)

Which camera model?

Also, what are your exposure settings? Canon DSLRs do exposure simulation in live-view. So if the settings would result in an over-exposure you might be cropping in to view an all white area.
