I have been using an off-brand battery coupler in combination with a 9v external battery and it has worked beautifully. Tonight the voltage on the external battery was accidentally changed to 20v instead of 9v, and before I noticed, the camera was turned on. The camera never turned and it still will not.
Has anyone ever done this? Is there a way to get this up and going again or am I going to have to send this in? Who fixes this type issue?
