olympus em-1

Brand new Olympus PT-EP14 housing, used once. I opted instead to go with a Nauticam, so I need to sell an essentially brand new housing. Original packaging with a Nauticam Flex Tray bracket with both left and right sides. (the bracket has a slight scratch on it, pics available upon request)...

Anyone else experiencing this? I’m shooting with an EM-1 Mark 1 in Nauticam housing, no problems until this year. On some dives, the camera simply won’t turn on - black screen, as if the battery is dead. But the battery is fully charged - and I always test the connections and everything else...
