Hi and welcome to FixYa,

Initially, remove the battery and let it sit for a while in that condition. This is to revert settings to factory default. Additionally, determine if your particular model has a coin size Lithium battery for memory back-up. If so, remove this likewise.

Should the above be not corrective, then it could be a number of possibilities. To determine which, the unit has to be opened up for a look & see as well as voltage checks. Fault could be:

  • LCD screen;
  • mainboard/LCD interface;
  • worst case scenario, faulty CCD lens (least likely).
Unfortunately, this type of faults could not be corrected with simple button/key pushing and would require electronics works/parts replacement. If you would factor in the cost of repair, the downtime and efforts needed to effect a repair, it may all boil down to no longer economically reasonable. This being the case, you may want to re-evaluate your options and consider replacing the camera.

Good luck and thank you for using FixYa.

Please reset camera and check live view result.
If problem still exist, CCD Imager is suspected.

Camara not focusing/ zoom not working


Its an error code and shows problem of Lens mechanism.
Lens focus / zoom motor is stuck that's why camera gives out of focus image.
You need to replace Lens Assembly and it would cost you more then camera worth.

Vibration hand image showing


Hand sign/ image means "manual focus" it doesn't mean anti-vibration. Press Focus button to cancel manual focus and ON the auto-focus. Hand symbol will disappear.

Picture ripples


The following describes the symptoms, cause and prevention of the Moire effect. Symptoms of the Moire effect When you are shooting a subject that has a fine regular pattern such as stripes or plaids, a ripple that does not exist on the subject sometimes appears in the image. An example of this can be seen in the pictures below. The photo on the left shows the fine plaids pattern on the shirt. The photo on the right is a distance shot of the same shirt. In this photo, you can see a ripple that is not visible in the photo on the left. This effect is called the Moire effect. Why does the Moire effect occur? Digital cameras and camcorders are equipped with imaging devices such as CCD sensors and CMOS sensors that have pixels that are finely aligned horizontally and vertically that convert light into electronic signals. When the pixels and the fine pattern on the subject overlap slightly misaligned, an interference pattern occurs and a ripple that does not exist on the actual subject may appear. This is the Moire effect. Look at the image above. This image shows red stripes and black plaids overlapped slightly misaligned. When you look at the entire image, you find a ripple that differs from either of the patterns. This is the same principle that causes the Moire effect. Preventing the Moire effect You can reduce this effect by changing the distance, zoom setting or the angle of the image. If you are using a camera with manual focusing, the Moire effect can be reduced by simply changing the focus slightly.
