HDMI Module Issue possibly

[CafeBass]

Since adding the HDMI module to my P3 Pro controller my flying max distance is shorter (less than 3,000 ft) and my video transmission flickers constantly. I never had either of these issues before the upgrade. Video transmission over the HDMI cable to my goggles is fine. After I installed HDMI module my RC firmware was updated to v. 1.9.2. Aircraft is v. 1.11.20 and App v. 3.1.51.
Any assistance would be appreciated.

As soon as I updated mine to those current firmwares it work one time and then no video feed it at all. I could control the aircraft but no video feed. Put new USB board in that didn't work. Had to buy new controller. That finally solved the problem.
