Hello Nikonians I am using Nikon D40X for past four years. Lately it has started showing a moisture problem. During rainy season, the camera simply does not switch on. Keeping the camera under 60 watt illumination also does not help. The service center fellow says the circuit has got the moisture. Servicing turns the camera on. But it is not affordable to service the camera repeatedly. Please let me know what can be done to avoid this situation.
