Canon PowerShot SD870 IS display doe...

I look at the display to take the picture, although the little icons are there (auto, iso auto, shakey hand etc) the display itself remains black. I can even take a picture, the flash goes off but still nothing shows up. This camera was working 2 minutes ago when we uploaded the pictures to the camera. I then deleted those pictures and went to take another and got the black screen of death...... This camera is only 4 months old.
I even tried resetting everything to original defaults. Nothing.
