Hi. My name is*****'m a camera repair technician with almost 30 years in the business and I'll be glad to help you with your question today.
Do the images taken display normally when viewed on a computer?
Just a note to see if I can be of any further assistance?
I can't really see how that could affect the camera. It's more likely a coincidental failure of the cameras LCD. These go bad all the time and need to be replaced. I would, however, suggest having this done by a trained professional at a Canon authorized repair shop. below is a link th their support page where you can arrange for the repair.
Please provide a positive Rating so that I may be credited for my efforts. If I can be of further assistance, please ask rather than leave a negative response.
You're welcome and if I can be of any further help, please ask.
