how do i fix the zoom

It depends; what exactly is it doing? Can you give me a few more details?

Agreed, Brenda. More info is needed. Although my first response is that maybe the zoom has been jarred out of alignment. Try cycling the camera on/off several times to see if the zoom can work it's way free. If not, and if your camera is still under warranty, the best thing you can do have Pentax should fix it.

If your camera is out of warranty, or if Pentax refuses to repair it for free, the one thing you can try is to gently, and I do mean GENTLY push against the lens with the PALM of your hand as you turn it on, it may cause it to depress back into the camera. If that doesn't work, and you can't reset it or turn it on/off several times, then you may have to send it in for a repair estimate anyway.

But understand that the average cost of a camera repair is around $180. As such, it may cost more to repair than it is really worth. The rule of thumb is that if the estimate for repair is north of 50% what you paid for it, you're better off taking that money and buying a newer and upgraded model.
