I too have sent two HDMI Modules back to Amazon myselfNo didn't think you were misleading. I thank you for your input! After eliminating everything else, all that was left was the module itself. It is already in the mail being returned to Amazon.
NO, I sent my controller into DJI got it back last Week and It didn't work! they failed to Test it before they shipped it back to me!, so I have sent it back to DJI and have been assured that they will Test it before I get it back!! Seems there are a lot of us having the same issues, I have 50+ years in Electronics and the Task was pretty simple and straight forward....BUT !!!! common sense didn't work for me either two times I installed them.Did you finally get one that worked?
