"Remove lens cap"

Yes, you can clean. Not as complex as I originally thought.
1) Remove all of the silver screws
2) Separate the silver case (should split in 2)
3) Remove the 3 black screws in the middle
4) remove the center square cover that is over the lens
5) Use a duster spray to clean the lense and mirror
6) Reassemble in reverse order
Not knowing what I was going to get in, the entire process only took about 7-10 minutes.

1. Power off
2. Remove the battery.
3. Put the battery to its place
4. Power on
5. If nothing happens
6. Replace the battery with charged one
7. Power on again

It should be work.

while the camera gets open,a sensor/switch willbe switchedON,but it is not so,the mechanism of the lens operation is defective,so get it serviced.

Since you said it makes noise when you turn it on, the gear system controlling the lens might be faulty. have it checked.

I had this issue and found a small grain of sand around the lens. On removing it the camera worked fine again.

Is your lens not retracting?
I've got the same problem and with the lens not retracting - this is why i get the message.

try to help the lens go out by pulling it very very lightly...

I had the same problem with mine after I dropped my camera when it was opening up after turning on. It feel directly on the lens and ever sense has told be to remove the lens cap.

I’ve disassembled the camera and discovered that the zoom motor drive assembly has a small set of plastic gears inside that are quite fragile and like mine are easily broken. You’ll find the zoom motor after taking the back assembly of the camera off. It’s located on the bottom left side of the lens assembly if you're looking at the camera as if you were taking a shot.

Here’s the part no. from the Panasonic support web site.....

Simple! Read warnings carefully! It said "remove lens cap and press SET button"! So remove the lens cap and then press the SET button (or arrow downward in the four directions button)! You don´t need to RESET anything...
