in Steve's review of FZ15, in sample pictures, there is one picture of the moon http://www.steves-digicams.com/2004_...s/P1010710.JPG

you can see those stuck/hot pixels. The thing, which i dont understand, how is it possible? As i know, hot/stuck/dead pixel are the LCD issues, but not the digital camera CCD problem, aren't they?

Hot and dead pixels do exist on CCD/CMOS sensors.
Longer the shutterspeed, the more likely is to see hot pixels or "oversensitive pixels".
However most of the cameras offer some kind of noise reduction with longer shutterspeeds that hides the problem.
Panasonic FZ10 for example automatically applies method called "dark frame subtraction"
when shutterspeeds over 1/2 seconds are used and this effectively makes those red/green/blue dots go away.

Just a while a go there was another thread about hot pixels:
