Can you more clearly what you mean "while taking photo"?If lcd not display image...is that any text or symbol in the lcd?If you can still see the symbol or text in the lcd, I think you have trouble in your lens or ccd.
Trouble in the lens usually make the lcd display white screen. And, if ccd trouble the lcd display white horisontal line and if so hard broken the lcd display black screen, but the symbol or text is shown.
