Having problems with your Casio QV-R4 Digital Camera ?

Lens Error I recently had a problem with my Casio QV-R4... every time I'd turn it on, the lens would retract and I'd get a "LENS ERROR" message on the screen. I talked to customer support and they told me that Installing the new version of their firmware, v1.01 would fix this problem. I've since installed the new firmware version, but I am still receiving the lens error. Has anyone else encountered this problem? Does anyone know how to fix it? Please help!!!


Answers :

As solutions 1 & 2 indicate, lubing the gears works!! This is a great camera, so I hope all of the QV-R4 owners try this. I may become a maintenance item for the camera.

\015\012I have a few additional tips.
\015\012
\015\012The gear that needs to lube is larger black gear driven by a small white gear. To get to it, only the back cover needs to be removed (don’t take off the flat cable to the back case; it’s a nightmare to put back on). There is a small motor on the bottom of the camera. The motor drives a small white gear that in turn drives a larger black gear. The black gear is hard to get to. To lube it, I used a hi-tech dry bicycle lube and a very small paint brush w/ long bristles. I also turned the white gear a few revs to be able to coat the black gear better. This may have helped get past the sticking point on the black gear.
\015\012
\015\012After two attempts the “lens error” was gone, but the white gear was still having problems turning the black gear. This set of gears appears to focus the camera, hence the image was blurry. Some more lube and spinning of the gears and the problem was gone. Gone I said, gone.

\015\012My beloved camera is now back in service. Total time to fix, 30 minutes (I actually took a bit more apart than I needed to J )
Even though I had the newest firmware installed (which can prevent from the lens error problem in some cases) after 6 years of usage I also had the lense error. As it was out of warantee and useless whith the lens error I decided to try to fix the problem by opening the back of the device. Swithcing on the QV-R4 while the back was opened I saw that the tiny white cogwheel below the LCD stuck and did not turn. All I did then was turning the cogwheel manually but carefully into one direction (as it was only stuck into one direction). After that it worked fine again. Now I am a happy QV-R4 user again :-))))\015\012\015\012P.S.: Please consider this only as a report of my successful try to fix my QV-R4. Feel free to try the same, but at your own risk.

I'm a new user of the D90 (and digital in general), and on my first major trip with it I had problem with the shutter not working. I would take some images, put the camera down without turning it off and move on to the next spot. At the second stop the camera would not work. I'd turn it off, remove the battery, run the lens in and out and eventually it would work again. The message I got was F--, which said that the lens was not installed properly. However the lens was never removed. What's
