This VTX was a tough one to repair... the reason for it being dead is that lipo voltage was fed to the 5v output. This resulted in a bad regulator, rf amplifier ic, rf generating ic. Usually in this type of situation its best to have the schematic and not go blind with guessing whats dead but, this is life, we can not have schematic for every electronics. I was lucky that I had on hand another unify pro 5v(pcb had a problem) from where I stole the ic's from. But only the rf generating IC and regulator are to be found the rf amplifier, unfortunately, has its part number laser etched out so that would be hard to find. But I hope this is a nice video from where you can learn something.
