I have a Pentax OPtio M20 7MP which I bought a few years back. After nine months of caring for it and using it, it just stopped working. The camera would not turn on. I put fully charged batteries in the perfect right places yet it still wouldn't do a thing when I press the on button.
yes,I have the same situation as you.it can turn on after some time without batteries.but now,it can not show anything at all.sorry for my poor english.
