Will the unify pro hv 5.8 still work if only getting 5v from the core? The manual says 7-26v but it does power up and goes through all the functions. I am not getting video but I do not know if that is the cause or if my tbs69 isn't working. Really wish the tbs69 had an led so I know it's working. Does anyone know if the vtx will fully function but not display an image if voltage input incorrect?
