Lens Error my Casio EX-Z77 makes a humming noise, and stays on long enough to say lens error.. and switches off. I have not dropped my camera. How Do I Solve This Problem ?

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ... Unfortunately, many cameras that fall prey to this can only be corrected by professional repair. But, here are some things that you can do that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty, they're worth a try.

This is probably THE most common failure among digital cameras.
There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

little cameras like the exilim have very tiny motors and gears and it's easy to get sand or dirt in the gears and destroy them, which is what I figure has happened to yours. Since it can't get the lens to do what it wants, it will not take pictures until the lens gets into the correct position, and since it can't, the camera won't fire

you might have pushed the lens into the barrel. small lens barrel has 3 metal pins that ride inside the larger lens barrel as it twists. Pushing it sometimes cracks the plastic holding these 3 pins in. one way to fix it is to carefully disassemble the entire lens barrel. be careful...sometimes a part just snaps, or is already snapped. The easiest way would be to replace the lens assembly with a good one you can get from another camera like this. There are no spare parts for cams like this so you can try to get another cam that has a different damage other than the lens barrel.

this is a common issue the lens gears are stripped. you have to change them out. if you do not fell confortable doing this it is recomended to take it to a digital camera repair company the only proble with that is like most people find out is their is not that many of us around and even if you do find one they might not work on casio. I do and their are a few others. hope this helps.

I did the same exact thing a couple of months ago. All i did was wiggled it around and then I pushed it back in place.

The warranty isn't going to cover if you drop it so you would have to pay for the charge. You can bin it if you like. That is your choice.

"lens error" will only be fixed by sending into repairs. 800-706-2534 and keep choosing option 2. Tell them you have a lens error and they will tell you where to send it.
