Took my 3 month old FZ1000 out to shoot photos yesterday and when I turned it on, the lens immediately went to full zoom and the camera died. I shut it off and on several times as well as removing the battery and still dead. Now when I turn it on, all I get is a click and nothing else. I can't even move the lens manually. JUNK! I'll have to send it to Panasonic.

Before sending it to Panasonic, fully recharge your battery. I absent-mindedly put in a discharged battery and got a result similar to yours when I turned it on. I replaced the battery with a fully charged one and it worked fine.
This is image file # P1700998 taken yesterday. That works out to 5000 images/month for the 14 months that I've had this camera.

2 frames short of 71,000 frames shot by this FZ1000. Camera survived temperatures ranging from -30C to +30C; rain and snow; dog hair and dander; and two drops onto hard ground.
I hope that is all that is wrong with your FZ1000.
