Question about Casio QV-R40 Digital Camera

1 Answer

Power doesn't stay on

I just put new batteries in and when I turned it on it made two click noises and shows a dark screen. The lens does not come out and the power button does not stay on. When I tried to upload the photos the computer did not detect the camera.

What type of batteries did you use? You MUST use brand new alkaline batteries at least (lithium or charged Ni-Mh are better.)

Sounds like the batteries are too weak to power the camera unless you had another problem with the camera.

There is something wrong with my Nikon D3000. It turns on but doesn't show anything on the screen and when I look through the lens it's shows a grainy dark film. It can't be the lense because I...


There seems to be two separate issues here. I'm going to assume you have a charged battery pack in the camera.

First, the screen. Turn the camera on. Do you see the menu when you press the MENU button? Does the shooting info show when you press the Info button? Can you see previously taken photos when you press the Playback button? If none of those show up then something is wrong with the screen (or the battery is dead).

Second, the viewfinder. First, make sure the viewfinder in the back is clean. Now turn the camera on and look through the viewfinder. Do you see the eleven focus marks? Do you see the info at the bottom? Now turn the camera off and remove the lens. Don't touch anything inside the camera! Do you see a mirror at a 45-degree angle? Is it clean? Look at the focusing screen above the mirror. Is it clean? Now look through the viewfinder and point the camera out a window. Do you see a more-or-less white blob, or the same grainy dark film?

THE SCREEN IS BLURRY AND NONE OF THE BUTTONS WORK.


Fixing a Lens Error on a Digital Camera
This has to be THE most common failure mode for a digital camera. Some common error messages that might show up on the LCD's of cameras with this problem include “E18 lens error”, or “lens error, restart camera”. Some cameras might show nothing at all, but merely make a beeping noise as the lens goes out, then in, then the camera shuts off. Sometimes the lens won't even move.
Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.
Fix #2: Remove the batteries, then remove the memory card. Then install new batteries, and turn on the camera. If you get an Error E30, it means you don't have a memory card installed, so turn it off, slip in the memory card and turn it on one last time.
Fix #3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particals that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.
Fix #4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.
Fix #5: Blow compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens. Other variations include blowing with a hair dryer in “no heat” setting, or sucking the gaps with a vacuum (careful with this one).
Now we're entering into the realm of potentially damaging your camera in conducting the fix. There is definitely some risk here, so take care when conducting the following two fixes.
Fix #6: Repeatedly tap the padded/rubber usb cover on a hard surface with the intent of dislodging any particles that may be jamming the lens. Other variations include hitting a side of the camera against the palm of your hand. A lot of people have reported success with this method. HOWEVER, there is also some potential for damaging or dislodging internal components with this method, such as unseating ribbon cables, or cracking LCD screens.
Fix #7: Try forcing the lens. More people have reported success with this method than with any of the other methods. HOWEVER, there's obviously some potential for damaging your camera by using this method. Variations include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Attempt to gently straighten or align the barrel if it's crooked or twisted. Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). While doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.

My camera wont turn on.


If the lens is stuck inside the camera and you hear a motor noise - changing batteries will not help. This has happened because the lens barrel is jammed inside the camera. Unfortunately, you will not be able to repair that issue. If the lens is stuck outside the camera, slightly tilted, and you hear a motor noise; you might be able to save camera. First, only use good batteries (stay away from alkaline batteries - waste of money), go with Energizer Lithium or Duracell Power Pix (you will get your moneys worth and have less problems with the camera). Second, very GENTLY, pull the lens barrel up and in the opposite direction of the tilt (to make the lens barrel straight), you will hear a slight click sound - DO NOT PUSH ON THE LENS BARREL!!!. Put in the new batteries and the lens should retract.

The screen reads "lens error, restart camera. I can not get the lens to retract. I can not get the power to stay on. The cannon screen shows up momentairly - but fades to black and the message appears.


remove the battery, let it sit for at least 2 hours, then put it back. put the batteries back, then gentle push the lens sideways to free its stuck part. if the error still occurs and the lens is not retracting, consult the warranty for the device as the lens assembly gears may be at fault.

Camera power problems?


It's not the battery. It turned out to be a memory card problem.

I took out my old memory card and put in a new one. It started working properly after that.

sounds like a battery power problem or problem with the terminal of the camera ; you know the point where the battery meets the camera.

Dark screen


Two reason for the screen to be dark
1. If you can see 'shadow' images on the screen, this implys the backlight tube or the inverter circuit has blown.

2 If No images show up at all then this is a mainboard failure
This is assuming the batteries are ingood condition and the camera powers up..

Check Vivitar support for repair/replacement options.
If under ewarranty it will be replaced
If out of warranty - New Camera Time
