Recently, in most, but not all, of my flights I get black lines in the video.

I am flying a Meteor75 lite with 200mW video power. This is the older AIO board that had both 25mW and 200mW option. I did not have these lines previously and only recently started getting it. Searching the net, the most likely cause is power to camera or VTX. How can I check or verify this? What else could be the cause of these black lines?

Black lines are usually caused by power issue. Being that this is an AIO FC, I can't see that you can do much about it.

I noticed it goes away when you let off the throttle. I would add a capacitor at the xt30 and/or esc

It has a BT2 connector. What value capacitor would you recommend?

I would try to fit a 470uf 16v... assuming this is a 2s whoop

i would choose a smaller one 200uf 16v or lower.

It is a 1s. Thank you, I guess 10v is good enough for a 1s.

If you’re strapped for space, i would even try a ceramic capacitor.... or I’d extend the cap wires with some silicone wire and place it where i can fit it.

Hope this helps your lines!

Good to know. Extending capacitor wires should make it easier.

Quick update. The issue is now resolved. It was a power issue as everyone pointed out. The main cause was the power line between the camera and the AIO board. It was held together by a few strands. I resoldered the wire. I did not need to add the capacitor. The video doesn’t have black lines anymore. 

 I am glad I opened it to put the capacitor instead of attaching it externally to the power cable. 

Thank you everyone.

....just curious, why smaller?

Sweet, glad the issue got fixed up!!

about weight and needed capacitance
