Question about Casio Exilim EX-Z4U Digital Camera

1 Answer

Lens error The camera is functioning okay in all ways,(viewing photos, and all menus) except that when I want to take a picture, the lens won't open and the LCD reads LENS ERROR, and automatically shuts off. The camera wasn't dropped or abused in any way. One night it worked the next morning it didn't.

Does it stay when you turn it off and back on again? These cameras have a function that shuts the camera down when there's a mechanical obstruction to the lens extension, It shuts it down to prevent more serious damage to the mechanism. Problem is, sometimes when triggered it doesn't return to normal. Try resetting it, either by the regular procedure, or by taking out the batteries for a few minutes. keep in mind that the lens barrel of this Casio unit is almost all the way to the left edge of the camera. Inevitably, when you hold the camera with two hands, one of the fingers of the left hand will overlap onto the front left edge of the unit, which, in fact, puts a portion of the finger on top of the edge of the extending lens barrel, either slowing its extension outward or aborting the extension process altogether. Even when you instantly jerk your finger away instinctively when the barrel rides the edge of your finger, you still have affected or interrupted the barrel extension process. In my opinion, a design flaw, but who am I to say? Good luck ;]

My digital camera FinePix A900, keeps turning off when I turn it on. Unable to pull any menus. Batteries are good. any suggestions, is it fixable or do I have to buy a new one?

Try pressing the playback button to turn the camera on. This should turn the camera on just so that you can view any pictures stored on the card or internal memory. You can also access the menu functions this way. Also try pressing the picture/shutter button and see if the lens extends. If the camera shuts off when you press the picture button and the lens does not move or only moves a fraction then the problem is probably to do with the lens

My camera is acting up

check the lens the lens might be closed if are open and hold for 5 seconds if it doesnt work take it to a specialist

Screen vibrates intermittantly. Also buzzing noise.

This is a problem with the lens gyro we can keep it from shaking it requires the camera to be taken apart and amodification done to the lens repair cost 65.00 in most cases.

Black LCD


Try pressing the "Disp" button, the LCD may just be turned off for power save mode. If you can still see the menus etc then the power save mode is NOT on.

If you can see menus but only take solid black photos then either your aperture is stuck and no light is getting inside the lens, or the CCD is bad and cannot capture the image.

Either way if its not the power save mode, we can fix the camera for you. Just let us know if we can help.

Error 99 is a generic error in that the camera does not know what the exact error is. The usual fix for this error is ......

Turn the camera off and remove the battery.

Remove the lens and clean the electrical contacts on the rear of the lens with a soft dry cloth.

Refit the lens and the battery and switch back on. Hopefully all will be well again.

Lens extended can't take pictures

The only thing not functioning was the lens I could turn on off see menus etc but could not take a picture and the lens would not retract - My husband cleaned the battery terminals on battery & in camera -IT WORKED !!!! good as new -

How to view

There are two ways to view the photos, in the camera...

1) if the camera is OFF and the lens barrier is closed, just press the Play (>) button once to view the photos.
2) If the camera is in SHOOTING mode with the lens barrier open, press the Quick View button twice in rapid succession.

When you are done reviewing the pictures, press the Quick View button once to turn the monitor off, OR, to return to the shooting mode, press the shutter button halfway.

Then use the arrow pads to go forward and backward.

Hope this helps.

My camera will not take photos

'I have opened the camera up and looks OK' How can you tell? what you have done is negated any chance of as repair or replacement. But a new camera?

When i turn the camera to take a photo, no image appears in the LCD or the eyepiece. this just happened all the sudden. I am able to view pictures that I've already taken in the LCD and the LCD will also...

there may be two reasons for this problem. 1. may be a defective or broken CCD. 2. the shutter is not working may be due to broken flex circuit cable. in any of the case you have to get it fixed from a professional camera repairer
