Hi Kyle,
Did you get any update from the Red Epic owner about this?
I'm having a similar problem at the moment, but I think it is related to the Red Epic v-mount plate.
I have my V-mount plate attached to my camera. It powers the camera fine via the cable attached into the v-lock plate.
I then attached a d-tap cable to my v-mount plate and then to my monitor a spark occurs. Camera turns off.
I try the monitor through another battery with the same cable and it is fine.
I try the monitor through the battery when it is connected to the camera and it sparks.
Is the v-mount battery plate causing this problem. As the d-tap ports on the plate do not work now.
Update:
As an update it only happens when I have the HD-SDI cable plugged into camera and monitor.
It won't spark if the HD-SDI cable is not attached.
Happens on both my Epic and Scarlet cameras with same plate. So it can't be a fault with both HD-SDI ports or shorting from inside the camera.
Problem does not occur when I power monitor separately and camera separately.
Thoughts?
Is the plate causing this problem.
