Try setting your WB to auto and take some test shots. You might try a shot in the house just to see if it changes.
I can only think of four things that would cause this:
1) Your white balance was set manually to something bizarre, not likely and I'm not sure you can get it that far off.
2) Some kind of filter over the lens
3) Really weird lighting from street lights or stage lights
4) A fault in your sensor
Based on your responses so far, I'm leaning toward the sensor has an issue. I would set the WB on auto or daylight and do some test shots with different lenses to be sure. But after that I think you are looking at repair or replacement.
You might try doing a factory reset, not sure how to do that on your camera but that would set everything back to the defaults and eliminate any possibility of it being something set wrong. But unfortunately it is not looking good.
