I have the camera Pentax *ist DS.
Some days ago my flashlight stopped working. I've tried a lot of setting, but it doesn't work.
The flash releases quiet good, but i can't take pictures. Everything is just "freezing" (I think it's waiting for the flashlight)...
I can only take pictures when the background is bright enough.
Do you have any conclusions? What could be the error?
I think that your settings are so far off that the camera won't let you take the picture. It does that and it's a good thing. Though, in digital, it shouldn't matter, since you get instant feedback from the LCD panel.
The AV, over and under compensation can give the same result... This halted my photography for about four hours one day until I set them right. Lost some good light.
