I have never heard of this type failure.
For any strange error, Sony usually recommends that you reset the camera to factory specifications.
Sony usually calls it "Initialize".
I can find only one reference to Initialize in the W220 User Manual.
That is on page 23.
The description shown does not say "set to factory specifications"
I suggest you follow the instuctions and see what the camera tells you when you attempt to do an Initialize.
Hi, I am not sure what I have done to my sony DSC W220 cybershot, but my pixel size has increased and whatever image size I select pics come out with a poor resolution and when I zoom in all I see is fuzzy pixels. Even on 12m setting they are the same. I have tried to find something in the menu and have tried different shoot modes but can't get the excellent picture quality back to the way it was. Is it time to buy a new camera? Thanks
