I have a Canon Powershot SX10 IS, have had it for almost 2 years. Yesterday, the flash stopped working sometimes. It will work every once in a while, out of no where. I have all the settings right (as far as I know) and even though the flash is up, it won't work. And the picture comes out darker than it used to even with the flash off. It looks fine on the screen when I take it, but when the review comes up it's super dark. But like I said, if I mess with it for a while it will work, until I turn it off and try turning it back on. Then it's back to not working. Should I take it somewhere? I have a warranty. Or any idea what is wrong?
