Same thing with me too. I was looking for a new camera until I came across the Sony offer on this camera on their web site.
They fixed the problem (2x batts, Power supply and internal chip) and got it to me early as I had to go on holiday. All no charge!
On my return I found an old battery for this camera and so I phoned to ask if they could replace this one as well.
They did (£59 worth) for free.
That is terrific service, I do agree Seadog!
