My camera lens isn't working, how can I reset it?

It sounds like there is dirt, dust or something else in the lens mechanism. I'm assuming you don't want to take the camera to a repair shop. I've had several cameras and this issue comes up periodically.

You can try:

1. using compressed air (with as thin a nozzle as you can find) to blow out the dust,
2. try powering on the camera and zooming the lens at the same time, 3. gently knocking the camera on a hard surface to loosen the lens mechanism,
4. manually forcing the lens to go back in. This can potentially damage the camera, but it's not working now, so you don't have a lot to lose.
5. Googling the camera model to see if you can find instructions on opening the camera up to clean the lens mechanism.

1. The Panasonic Lumix DMC-TZ3 mini charger includes a separate car cable , no AC adapter. It is very handy, very easy for travel and daily use.
2. Dual charging modes- Rapid Charging mode charges battery to 90% full then the charging circuit switches to low current top-off charging mode to bring the charge to full safely.
3. LED indicator displays battery charging status.
4. Battery charger equipped with automatic constant current control which protects battery from overcharging, short circuit, and electric shock.
