This is common when you use a memory card that isn't recommended by casio. They only recommend using sandisk, toshiba, panasonic memory cards. Try one of those and you should have no problems.

Please download a backup of the firmware from this site: http://www.oborona.net/stuff/qv-r40/QV-R40.zip
Turn off your camera. Press down "Menu" and "Disp" simultaneously and hold down, then press the power button until the camera turns on. The display will now display some tech gibberish. Quickly press the ring joystick right 2 times, then press "Menu" again.
You should now be in the engineering menu of the camera. Please do not change settings in here. Now the camera can be connected to the PC via USB. Place the file from the start on the camera.
Disconnect your camera and turn it off. Hold the "Menu" button down and turn the camera on.
You should see "PROGRAM UPDATE" on the display. Select "Yes" and wait for 30-60 seconds, while the camera starts flashing.
Your camera should now be fully functional again.

Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

turn the camera on with the button on top, then take off the lens cap and insert a memory card into the side. The pictures will save to the memory card and you can buy an adapter to connect the memory card to your computer to view and save the pictures.

The Camera would work with 4 AA batteries of almost any type. However a high capacity rechargeable battery would be more economical in the long run and you need a charger too. NiMh batteries with capacities of between 1200mah and 2900mah would be fine. The Hybrio type comes ready-charged and retains its charge best on the shelf. Therefore I would recommend e.g.
Four, Uniross Hybrio AA 2100mah rechargeable batteries

The problem is that the lens has become stuck in the barrel after dropping it. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful.

I just had this same issue. Try holding the ON/OFF button down for several seconds.

The reason for this malfunction is in-sufficient power, try cleaning the battery connecting terminals of the camera for rust/oxidation/moisture

I have exactly the same problem: Inside is quite ok but outside is impossible.
I am searching for a solution.
If I find something I'll tell you

I had this same problem years ago, couln't fix it in any way. Tried the description on http://www.oborona.net/stuff/qv-r40/eng/index.html (reloading firmware) but even that did't work. Found my old qv-r40 today, and gave it one more try using the above mentioned solution of updating the firmware. Even though I only did again the same as a few years back (updating the camera with the same firmware), this time it worked. Got my old camera working again!
So I suggest you try the solution by oborona.net, and if it doesn't work get the batteries out and wait for a few days before trying to update the firmware again.
