Thank you for helping me, too! And don't be put off if you need to whack your camera more times than you think could possibly be healthy. I gave my Sony DSC-T1 (error code E:61:10) a good long beating after reading these messages, but with no luck at all, so I gave up for a week. Then yesterday I tried again and it started working after the first couple of whacks! Perhaps more amazing is the fact that my camera appears none the worse for its ordeal. It is certainly made to withstand some pretty brutal treatment, and it's great to have it back without the huge repair bill Sony wanted to charge me. Result!
