Well a comination of issues, one being the wi-fi. I also had three occasions of the camera being completely unresponsive after a battery change, and then the mushy button. Not great that they've had so many of the motherboards go on these cameras, I hope the new ones last longer.
Out of curiosity do Sony offer a warranty on their repairs? I won't need it any time soon as I still have roughly 18 months left of my Panamoz warranty. In hind sight it's a good job I bought from them, if I'd had the standard 1 year warranty I'd have a large bill to pay
