Camera Will Not Power On - Was working previously

Hi,

I received a Lumix DMC-FX3 camera which had the lens jammed open due to sand getting in the mechanism. But it powered on then shutdown.

I manged to disassemble the lens and clean out the sand.

I tested the camera while still disassembled and it seemed to work - the lens mechanism was still a bit noisy so I decided to remove all the grease and clean it thoroughly before applying fresh grease.

When I assembled the unit - it now longer powers on.

There is no sign of life - no flashes from the LED no noise from the motor.

I charged the battery and checked & cleaned all the connections with isopropyl - but still nothing. Completely dead.

It seems to me like a protection fuse might have gone - but I can't easily find on on the pcb.

Does anybody have any experience of this camera?

Or have the service manual for it?

Thanks,

Mark.
