Canon 5d mk iii - no power

[amjadpics]

my canon 5D Mk III will not power up. During a photo shoot my camera went dead and after changing the battery it never came back on (no power)

Of course you tried a brand new battery?  And you checked out the charger for proper operation?

If, yes, you probably need to send it to Canon service.

nothing not even a light
