Question about Casio QV-R4 Digital Camera

5 Answers

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!!!

Re: Lens Error

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.

I have a few additional tips.

The 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.

After 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.

My 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 )

Re: Lens Error

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 :-)))) P.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.

Re: Lens Error

Hi. (copying my post here that I first posted at http://public.ok2life.com/comment/index/26 ) ... I had this same problem on a Casio QV-R4 - which has been a great camera otherwise - and managed to FIX it !! . Exact symptoms of my problem: on start-up, lens would extend to about full length, then I would hear a quick clicking/whirring sound of some kind of gear/cog failure. Next the lens would retract itself, the LCD screen showed "lens error" and the machine would power-off. MY FIX (might not work for everyone): Seeing it was way out of warranty AND has fungus on the lens anyway, I took the back off and started the cam... over and over, looking for the problem. Eventually I could see that down at the bottom of the Cam, on the Lower right side of the LCD the is a small white plastic cog which made the strange noise. Next to that (it's very difficult to see) the white cog drives (?) a larger black one - it may be something to do with the focus mechanism - but thats just a guess. Trying to move the cog gently with a tiny screwdriver I could feel that it got stuck on a tight spot once every revolution in the same place. Tried to work the tight spot out with no luck and thought - "what the..." I'll squirt a tiny drop of WD fluid in there on both cogs (seeing the camera was useless to me at this point). Lo and behold a few minutes later the camera started just fine, lens extends and contracts properly with NO ERROR!!. So ... if your Casio QV-R4 is out of warranty and otherwise headed for the trash can try this - it just might work. ## NOTE - I'm 100% certain that no Digicam manufacturer would recommend using oil in your camera. It would most probably void all warranties. If you do it - use as little oil as possible and apply it to as small an area as possible. Wipe off any excess after. The only reason I tried this was because the Camera was otherwise out of warranty and useless to me as it was. - Now at least it works - but I still need a solution for fungus on the lens!!Anyone interested came e-mail me at dukey_e(AT)yahoo.com.au (use @ symbol obviously!!). good luck - E

Re: Lens Error

Yeah, apparently the firmware update prevents the problem from happening. It doesn't actually fix it. I sent it to customer service and it was going to cost $250 for them to fix it. It should be covered under warrentee but I didn't have mine...now I'm out a camera. good luck, sorry for the bad news.

Re: Lens Error

I also have the same problem, called Casio, they said it is a circuit board problem that causes the lens error, and that the part costs about $260. A firmware update after the problem will not fix it, the update was just to prevent the problem. Unbelievable!! Never buying a Casio again, will stick with Canon.

I have a casio digital camera qv-r52 3x optical zoom when I turn power button on it will not stay on the lens retracts but I can view the pic's on the dish


Katie, Joe alerted me to your problem. The symptoms that you're experiencing suggest that you're experiencing a lens error. Lens errors are fairly common, but there are many causes. Some causes include poor or drained batteries. Or 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 ...Here are some troubleshooting steps that you can try that may (or may not) correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them:

Lens error of casio EX Z300


The lens error is usually caused by mechanical faults concerning lens assembly. This happens because there is dirt inside the lens (sand dust), or one part in the lens assembly is bad or went out of place.
Because of this he lens cannot extend or retract fully, the error is detected and lens error is returned.

Sometimes this can be fixed playing with the lens during extraction or retraction to help the lens asset getting back to normal.
If if does not extend tapping gently the back of the camera, and if it does not retract helping lens back in while turning camera respectively on and off.

More often the camera lens must be disassembled and re-assembled by a technician to fix the problem.

Casio Exilim EX-Z60 won't turn on


This happened to me too, fiddle with the lens as its obviously stuck. Don't be too rough but try to figure out if it is slightly bent.

You will only be able to this if the lens is sticking out a little, enough to get a grip.

Good luck

Resetting EX-V7 error message


Hey Go here
http://world.casio.com/qv/download/en/ex_v7_firmup/
Download the latest firmware. Install it. Like the rest of the people. It seems like we all dropped it. And updating the firmware seems to help a bit.
Meaning you can now use tha Camera and take pictures, but when you turn it on, you will get the same error message for like a second. Then the Camera is back to normal.
If its under warranty take it back. And dont tell them it was dropped.
Cheers !
