Hi I have the Zenmuse H3-2D on a P2. Used it loads to record but only recently set up my FPV gear. I added MiniOSD and a 200mv transmitter. Everything works fine and I can see the OSD data on my screen, but i dont get any video from the GoPro being transmitted. Tried all different settings. It turns on and charges OK when i turn the P2 on. At first I thought the pin out on the back of the GoPro may have changed from teh Hero HD to the current Hero3 but everything I read on the net tells me it's the same. The HeroHD, P2 and MiniOSD all have the latest firmware. I'm confident my soldering is solid as I checked end to end for continuity. Any ideas? I will upgrade to a Hero3 if i need to, but i have stacks of HeroHD laying around that are begging to be used.
