Rob-
Sorry about your camera. Is it still under warranty? If it is, you'll need to send it in so they can replace the flash. They might even need to replace the whole camera. If it's not under warranty you'll probably need to buy a new camera. I expect the cost of getting it fixed will be about half what a new camera would cost.
Please post a review for your V4. We don't have any reviews for that camera. Here's a link to that review page: http://www.pcphotoreview.com/cat/dig...6_4337crx.aspx
