OK we know it is not the lens. Next get a new battery and fully charge it. Make sure it is fully charged. That will eliminate the battery and charger.

As a test (this is just a "test" -- not a fix), please switch the lens to "manual focus" (swith the AF/MF switch on the lens to the MF position) and try taking a photo (it does not matter if you focus or not). Let us know if the camera shoots -- that's all we want to know.
If the T1i is in it's default "One Shot" mode and the lens is in the AF position, then it will ONLY take a shot if it can confirm that it has locked focus on at least one AF point. If either the lens is in MF mode -or- if the camera is switched to "AI Servo" focusing mode then it will take a shot whenever the shutter button is fully pressed and it will do this whether the camera was focused or not.
That means this is a simple way to determine if the reason the camera is refusing to shoot is becuase it cannot focus.
