great little camera - but now every time switch it on the lens protrudes then retracts again flagging up "switch power off and then on again" I tried taking the battery out - keeping the power button pressed for 30 secs etc with no change. I've also tried resetting it but by the time I try to initialize reset the switch it off then on again flag pops up and blocks it. Can anyone suggest a fix? Or does anyone know if its a relatively easy and inexpensive repair at a sony dealer?
