Hi All,

I have a new zenmuse gh4 gimbal and have been using it fairly successfully with Lightbridge on a s1000 with a2 over the last couple of weeks. The only issue I had was occasionally losing control with lightbridge and a2 going into failsafe. Plus on other occasions losing  the picture. It was fine 95% of the time, but I lost confidence in lightbridge, so decided to try it with IOSD Mark II and an AVL58.
Now I've run into more problems. I've checked my connections and assembled everthing as shown in the manuals. When I power up the system, I always get the red flashing light on the bottom left of the zenmuse when I switch the camera on. It's green before I boot the camera, then always goes to blinking red. I get all the OSD info coming through on the monitor but no video.
I tried reconnecting Lightbridge and it still worked fine with video feed. I've checked that all firmware is up to date.

Does anyone have any idea what the problem could be? Or will the gimbal have to go back for service?

Problem solved. I didn't realise I had to switch the switch from HD to AV. Doh!
