Canon sd850 is lcd issues

I have an sd850 is and my lcd sreen my pics and all the settings dont fit in the screen any more everthing is too big .So all you get to see is half the picture and when you go to the set up screens all you see is half the print because its all too big. Is there a fix for this or what did i do wrong with my camera.
Thanx timmyy

Does what the screen displays also look very coarse or grainy? Does the screen when you're composing a picture also look too big?

It looks a little course and grainy but it just seem to me that the lcd screen is just zoomed in and stays that way. every thing is too big .

Then it's nothing you did (at least by pushing the wrong button(s)). The camera will need to go back to Canon for service. Is it under warranty?

no I wish it was still under warranty. What part would it be to replace do you know. I could just replace the part myself if I knew what part it was.

Could be anything from a ribbon cable to the main printed circuit board.
