Hi!

Please check the "Troubleshooting" part of the manual to this camera.

I wish I could offer some simple solution, but the lens has somehow gotten damaged and is no longer able to focus or withdraw into the camera body. It could be as simple as some sand in the lens, but even that will require a trip to a camera repairman 

you should call KODAK Technical Support thru this number 1800 235 6325 op 12 op 2

i had the same problem, if you try to turn the lens in as if you turning a dile, the lens will go back in manually once you have the lens completly in again, as if the camera is switched off, then turn the camera back on at the power button and the camera will operate as normal, this worked for me i hope it works for you too.

the beeps mean the lens can't be opened or closed. maybe something stuck or it's just failed?

When I turn on the camera. the lens will not extend. The screen
will not show anything but a message, " date & time are already
programmed". No menu item works. Pictures cannot be taken.

same model as mine. Next to the memory card slot m rectangular black box.. battery pack. press it and it comes out , put it back and hold the on switch... presto!

Lens is most likely been knocked out of place, that would be the reason why you have out of focus and/or blurry photos. This would also be the reason why you can't retract or extend the lens.

Gently pushing on the lens MIGHT fix the camera, but I would only try as a last resort. Sometimes all that is wrong is the gears get out of place, and by gently pressing on the lens, it snaps the gears back in line, which will bring the lens into working order again.

Leave the camera sitting with no batteries overnight. Then in the morning install ONLY Kodak AA batteries. I had the exact same problem.

hi the problem that causing this is: there is some pressure to the lens did it fell? probebly there is a fault in the lens sorry cant help good luck
