Help With C302zoom

[fless1]

I have been using this camera fine for 2 years now. At the weekend, I was playing around with settings and now when I use flash on P mode, the picture is really dark, although the flash goes off. Slow flash is ok though. I can't see it's anything I've done as onremoving batteries, factory defaults are set, which I normally use.

HELP1 PLEASE!
