When you get it back it will once again be a totally reliable camera, and you will be glad you sent it in.
I had an old 3mp Digital Elph go bad, out of warranty. The sensor had some kind of problem with it's attachment or something. Canon could not repair it because it was about three years old, but because it was a manufacturing defect, they sent me a refurb 10mp SD770 IS to replace it. That little camera is great.
I can figure that made up for the following out-of-warranty repair of my 20D which cost me a couple of hundred dollars for only a cracked top LCD Screen cover. (Banged it against the gearshift in my truck). It came back all checked out, cleaned, and good as new.
So send it for service and enjoy it when it comes back in good, reliable shape.
Trying to shoot yourself doing roll-backs? Haha, but 200 bucks for top LCD ouch... I thought repairs were mroe reasonable than that. I was thinking a shutter replacement would be about 250, not a chunk of plastic for 200. Yikes
