I have a TBS evo, kakutef7miniv3 fc hooked up to a foxed t-rex. I’m getting video but it’s really hot and mostly blown out.

* I connected a Unify HV to my wiring harnesses same thing.
* Replaced wiring harness, same issue
* Replaced camera with ratel, no improvement
* Wired camera video directly to VTX, perfect image but no OSD.

Obviously something with the FC, checked for over solder or splatter under magnification nothing I could find.

At this point it looks like I need to replace the FC but was curious if there any insight into why this is happening or any hell mary ideas to resolve?

Thanks

If you have the vtx turned on but not flying, you will burn out your VTX. The air flow helps cool it.
