I was having a problem with my Dji Phantom 2 Zenmuse H4-3d. It was not pairing to the remote and in turn was constantly flashing Yellow. Upon searching for the problem and possible fixes I came up with absolutely nothing! But I did find other people on this forum with the same issue and no fixes. Well I have managed to find the fix, its not firmware.... Your Receiver is stuffed! A simple replacement and you are good to go once again. I have made a video ->

Good job

I have exactly the same problem bud. Did it work long term? Also where did you buy the replacement receiver from?
