Sounds like the board. Most likely they will want you to send it out for repair, then the cost of shipping and what repairs they will cover under warranty might or might not be more than the camera is worth. You can try it, just make sure they give you a quote for any costs beforehand.
It's a shame, but most of them are basically disposable. I've torn apart quite a few and sometimes it's easy to see why.
I take quite a few pictures, both for pleasure and for ebay. So I go thru cameras. I normally buy something used a few years old for next to nothing on ebay, and use it until it dies or I run across an upgrade.
What I look for is lens quality (I prefer Leica), a decent zoom, and performance indoors in low light situations. I don't need to see every mega pixel, nor do I need to spend the extra time uploading all of them. Currently have an older used 5MP Panasonic Lumix that I have under $10.00 invested in including shipping. It replaced a more costly 16MP Fuji that was just a total mistake. The cheap Lumix shoots 100x better with a lot less fuss.
