Panasonic DMC-TZ5 will not turn on

I had a similar experience, both with my original TZ5 and the replacement TZ5 Panasonic sent me. I was mystified at first, but now I think it's the AC adapter I was using. With the replacement camera, absolutely nothing happened between taking pictures of my new house and plugging in the camera to export the photos. The back of the camera near the AC input got really hot and my surge protector shut off. The camera won't turn on. I don't know about warranties, but if you think that's the problem and were using a Panasonic AC adapter, you should check. My (non-Panasonic) adapter worked ok the first time or two I used it.
