My LUMIX camera us stating “System zoom error”

I had the same issue. I read on one of the help sites to gently but firmly bump the side of camera with the palm of your hand as you turn it on. I did this and the lens un-jammed. I then sprayed Teflon spray on a clean cotton cloth, extended the lens completely and GENTLY pulled it out another half inch. I then wiped all sections of the lens barrel with the Teflon coated cotton. I waited a couple minutes for the Teflon to permeate the plastic barrel then wiped any excess off. The lens works perfectly now and every time I turn it on or off, it extends and retracts as well as ever. May have been a moisture issue, or granular dust, but it’s clean and working well.

I tried to do the same thing to my camera and did not work :( What else can I do?
