And I picked up some FinePix t210 for 20 bucks more so your comment about repair is right. As prices plummeted they now are cheaper to replace than fix.
Had my Canon powershot sd850 camera for a couple years that worked fine until I recently turned it on to a blank screen. It will still take shots but can't see what you're taking. By reading other threads of Canon cameras with same problem, seems it's not worth fixin. I've tried recharging batteries, changing modes on camera but still the same. It's dying after 3 years of very little use of this camera.
