Have had DSC-P71 for about 8 months without problem, but camera started to play up on the weekend. Whilst I could view previously taken pictures, I couldn't get the camera itself to come on - almost as if the lens was jammed. It would 'beep' but do nothing else. Worked every now and then for a moment, but would then shut down again. I had been using the camera with ordinary alkaline AA batteries (which Sony do allow) but problem SEEMS to have gone away now that I have loaded back in recharcheable Ni-MHs. Is this just a conincidence? I've used alkaline batteries in it many many times (more in fact than the rechargeables - they're never charged up when I need 'em!). Is there some sort of long-term memory problem if I continually use alkalines? Can't find anything about it in Sony documentation/web site. Thanks for any help anyone can give.
