Flash will not work, Pictures at night blurry

Do you get an orange range light?

Make sure you are using regular batteries and not rechargables, they can be problematic in any point and shoot camera. The best I've seen are the E2 and long lasting. You might pay a little more for those, but literally in the long run, you will be happier not have to recharge every couple of days. I did this and it was annoying, changed to regular batteries and I go for months at a time. Flashes can wear batteries down pretty fast.

The next reason why the pictures are orange, is possibly because of the White Balance setting. Make sure the camera White Balance select saus AWB (Auto). If it still comes out wrong, then put the camera dial in another White Balance selection and take another shot, if the same subject and lighting comes out warmer (more red) or cooler (more blue) then you know the settings are off and the camera should be service.

Maybe check for a new firmware at this link.

Happy snapping.
