Last January my S2 IS failed because of a stuck shutter. I had wrote canon support who wouldn't offer to fix the camera under warranty.
Next, I tried to fix it myself but couldn't and the camera has been in hundreds of pieces in a zip lock bag sense.
I decided to email canon again today explaining my situation. I don't think I'm in luck as I have my camera in many pieces but here is what I got back.
1. If a PowerShot S2 IS is received by the Factory Service Center with
a problem description of no image, (either on the LCD or the memory
card) and it is determined this issue is caused by the shutter sticking,
Canon will provide a No Charge courtesy repair.
2. If the camera shows impact damage, evidence of abuse, alteration, or
mishandling, or is otherwise ineligible for coverage under the limited
warranty for the PowerShot S2 IS, the FSC will prepare and send a Repair
Estimate, which must be approved by the customer prior to repair.
