When i turn on my panasonic lumix dmc fz28 it shows system error

Hi,
I suspect the snap key is shot circuited, use contact cleaner spray in the click button often press it to get ride of possible carbon shot circuit between the switch. in some cases the processor will malfunction, and if moisture or water particles gone inside, you must open the cam and clean the motherboard thoroughly with PCB cleaning agent.

See http://www.fixya.com/support/r13011856-lens_error

This is a lens mechanism fault. USe can of air and spray on surrounding the lens For cleaning the dust. and then try.

Try these procedures.

Does it make 2 beeps and have a green spot in the center of viewfinder/lcd? if so it is thinking it is focused, test this to see. If it is 2 beeps but definitely out of focus, it will need to go in for a back-focus alignment. Simple operation for the repair team.

there is a small gear on inside zoom lense that one not working chaing that part

I have this problem too, but only when I try to view pictures I have taken on a later model. Photos taken with the FZ28 view as per normal.

when i turn on my cam it showing to me Error in the system (OIS) what the solution plz??
