I could use some electronic guidance here. I have an a7s ii and monitor both powered from dummy batteries going to an AB multi tap connected to a v-mount battery. The hdmi port stopped working on both the camera and monitor and I can't figure out what caused the issue. I'm starting to suspect that the micro to full size hdmi pigtail I was using is the cause, but I'm not positive.
Excuse the truly terrible photo.
Is there something I can do electronically to prevent this from happening again?
