I did something really stupid and allowed the red and brown cables to touch at the solder joints with the power on in the process of installing a fpv tx on my phantom 2. Now there is no power coming from those cables. The video pair of cables is still working fine. What is the best way to go about powering the tx now... do I need to replace a board that I fried or is there somewhere else I can get power? I'm obviously a novice, so I'm looking for a reasonable simple solution.
