Would need someone to help me with the below: Yesterday when I was clicking pictures I changed some settings and now when I click pictures they are like I have switched blue lights, but I haven't. Also without flash the picture is all black. Seems the camera is compelling me to keep the flash on all the time. Can someone please help to restore my settings.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
"Switching blue lights" sounds for me as if you have wrong white balance. Find this option in your setting and set it to "Auto".
Black picture without flash might be wrong exposure values. Without knowing your camera model it is difficult exactly to explain how to change them. Anyway, try to set the camera to automatic mode.
Since we don't know what settings you had before yesterday, we cannot help you to restore them. But you can always reset your setting to the initial. Find in the camera menu "Factory reset" and after you perfom it, your camera will have setting as if you just bought it.
