We have a Panasonic Lumix DMC-FS42 camera, just over 12mths old. I plugged it into the pc via the cables (unfortunately, not the correct cables) and now it wont turn on or off. It shut it self off with the lense out. We found the correct cables, but it still wont work. Battery is fully charged. What can we do? Is it ruined now? the *other* cable fitted, so i *assumed* it was the correct one *doh* Thank you.
