OK Solved!!!!!!!!!!!!!!!!! Well, asking me about the white balance.... I thought I had not changed anything and it was set to auto. It was set to auto and in my usual Nikon world, auto just means auto. But, when I just went in and looked at the auto white balance there is that color pattern where you move it from center to the red, green, etc. quadrant. Somehow, I had looked at that, and unknowingly moved it all the way to the lower left, green quadrant. Probably because I was in bright sunlight and couldn't even see that moving.This was sort of an accident. I thought because it was on "auto" it would actually mean "auto", but if you have moved that... it isn't exactly "auto."
Anyway, I am very happy not to have to send this for repair.
Thanks for your help. It always helps to ask the right question.
