I have a black screen on my Phantom 2 Vision +... It became like this, few days after I updated the Firmware from the official site of DJI. Please let me know if I can send you my complete drone to you to repair (I think is the wi-fi module...) and if you can do a checkup to my machine. And how much will it cost to me. Thank you in advance for your awnser. BR, from Portugal, Carlos Sousa
