having trouble with my D40.
hi bettycw if your nikon d40 body is not working time to move up to newer nikon body due to the price of a expensive repair job , you did not state what lens you were using that would not auto focus that also can be expensive to . if its a nikon d40 gone bad than move up to newer body like a d90 , d7000 or a little less expensive with more megapixels d3100, 3200 5100 nikons and there are some good deals going on now for nikon camera and lenses that you can get now . well good luck hope i helped gjr
