Hi All, I have a Canon 6D Mark ii just over a year old (out of warranty) that I haven't used in a few weeks, Took it out yesterday and turned it on. Dead as a door nail. Thought it might be the battery (Canon brand) so made sure it was charged to full. Put it back in, no joy. I've seen loads of 'tips' videos on youtube and spent hours online researching but nothing works. Any tips before I send it off to be repaired and am charged an arm and a leg? Thanks!
