I have a Sumsung L201 digital camera & autofocus will not work. If I try zooming, It does it only once then will beep & switch off if I zoom any closer. if the target is within range, it takes nice pics.

The non-functioning of the camera can be a fault in the zoom or auto focus sections and may be due to the failure of the Main control system or the drive. This seems to be a mechanical fault and a simple way is to reset.Remove the battery and card for some time. Now replace only the battery and while switching power ON, tap the lens hood on the palm of your hands so as to disengage any dirt or mechanism being struck. When the lens comes out try and pull the lens with care , repeat till the lens comes out totally to free and realign by itself.

If not we need to open and check for a jamming of the lens system:

Use some air to blow between the lens to dislodge any sand particles struck inside. Unless you are familiar with handling of small devices must the camera be opened. If so check the voltage on the motor drive, check the auto focus and Zoom drives, it must be free with manual movement. If jammed the motor can be removed and released. If none of these works then you can think of taking consensus with the service centre.
Get estimate before you decide. It will be good to have it checked at the authorised service as you do not have to run around for spares.
