Help! I am having a problem with my pentax optio t10. It switches on fine and i can view photos that i've taken okay too - but when i try to take new photos with it - it focuses, makes the right noises but then doesn't do anything...it won't let me take a photo - no sign, symbol or message comes up to indicate a problem - i'd appreciate any pointers at all - many thanks in anticipation!!

My optio t10 did basically the same thing...turned on, lens goes out, then automatically shut off. I took the advice of a solution listed here for another problem...hit the camera. For whatever reason it worked.

Hold the OK key for 5 seconds while powering on the camera. this unlocks the menu and key modes.

You probably set the auto power-off for energy saving

If you're using an sd card or most other standard memory cards you can buy a card reader very cheaply and plug it into the usb of your computer, your computer may even have a reader built in
