The Issue/problem is that I'm getting NO FPV VIDEO! I have had this Exact same problem in the past & was able to fix it with the use of a NEW Memory Card....Not this time..not so lucky! As you can see from the photo on the bottom of this post, EVERYTHING works great EXCEPT No FPV Video?? Now I'm guessing that the FPV Booster App that I tried doesn't register anything due to this issue?? IDK but for that sharp troubleshooter I thought this might be a helpful clue?? I do have a FPVLR stage IV upgrade...And I am using the "1.0.48" DJI App/I'm running the 3.8 fimware ***NOTE: I spent 3 hours researching this ISSUE & found that I am not alone, there are dozens of folks with the EXACT problem!! However I have done all the fixes that I found.... Including the ARCTIC SILVER SHIELD Treatment of the WiFi Module due to the item mentioned In the RC Groups.com site it states that the WiFi Module is poorly heatsinked!!----they recommended having the Arctic Shield Treatment done..as I have... I'm actually embarrassed to say how much I have spent on this platform, including PROFESSIONALS doing all the work! (I'm not saying that the guys who did my work caused the issue), and when I want to use it for my first huge deal...yeah :x :x I tried the following; a. 4 different SD cards (this has been the fix in the past when it did the exact same thing) 1 of which is a Samsung 32-EVO Class10 I reset b. Tried all six (6) different P2V+ batteries all fully charged 2 are the brand new type & the other 3 are the older types c. Tried 4 different machines Iphone4s Ipad-mini-Moverio Bt-200-Android 7" I read that the newer iphone firmware upgrades were an issue, so thats why I tried out the Moverio & my other 7" Cheap/Android (no dice) d. Tried different viewing settings for FPV e. Checked & recharged all batteries for the Tx (I have the new V3 TX) ** BYW: My Flytrex works perfectly... I don't know what else to try?? Now EVERYTHING continues to work except the FPV on screen? The Video camera & Still camera will shoot & record?? All the Telemetry works fine? The only thing that is not functioning is the FPV??? Any Pro-active help or suggestions is much appreciated!! Moose The photo on the bottom shows you what I'm seeing with the DJI app ...it just keeps showing that twirling center... But never kicks in? The photo directly underneath is from the FPV Booster App?
