Learning my new to me P4P. I got DJI Googles with it and when I plugged in the HDMI cable the aircraft disconnected from the controller. Total disconnect both Goggles and Ipad. I unplug the HDMI cable and the bird connects again. Went through the posts and found a posting about the same thing and he advised to download the firmware and flash the controller a couple times. I did that, then went to plug the HDMI cable in again and it stayed connected until I plugged in the goggles. The screen cycled from "Ready to Fly" to "Weak Signal" to "Aircraft Disconnect" and kept going through this cycle every few seconds. I turned everything off and disconnect the HDMI cable and then turned on the Ipad and controller again. Now when I open the DJI Go 4 app I get a white screen and a message that says this app does not go with this controller. Shut everything off again then the big problem hit. I press the power button on the controller and I get a solid beep sound from the controller. I press the second time and the LED turns a light green/blue color (not the green of being connected and not the blue of downloading firmware but a light green/blue). The light does not turn red showing no connection. The LEDs show the battery at two lights and the third blinking. I thought it was a low battery signal so I plug it into the charger and the lights start to flash in sequence but the solid beep sound is there and does not go off. After 30 minutes the right side (near the plug) is very warm. Any ideas???
