Why no sound?

This camera accepts a 512 mb sd card maximum. If you try 1 GB or bigger, takes a couple of shots and freezes.

Check to make sure battery compartment isn't damaged. If it isn't might be time for a new camera...sorry

My 33LF won't work with even a 1gb Memory Card. It freezez up as you describe.So far it seems happy enough with 512mb cards. A camera shop operator told me that the capacity of the card exceeds the capacity of the camera and it seems he was right.

lens problems , need replace the lens or fix the lens very easy to fix that lens ,

The easiest way to erase the entire card is to go into the menu and find "format"...follow the on-screen instructions

According to the Pentax web site, there is no firmware update available for the 33LF camera. As far as your pics are concerned, you can use a card reader to download them to your computer. Then, you can format the card in the camera and everything should be ok.

Easiest way...format the card in the camera.

This camera supports only 512 mb sd card. If you use any bigger, it freezes. Tried with 1 gb and 2 gb and freezes, while 512 is just fine for the size of the pics of this baby.
