I bought my wife a Canon SD1100 IS about 7 months ago because she didn't have one of her own. She uses it occasionally and we've never had any problems before.

Last night we noticed that when it was turned on the screen would have horizontal lines flickering across it. Today, I go to look at the pictures we took last night and the camera won't even turn on. I've charged the battery for a little while and still nothing...won't even turn on for a second. I used a backup battery and still nothing as well. Any ideas?
