phantom 2 not binding to njd6

[maelim]

My phantom 2 crash im one of our shoot and I just recently bought njd6 since the old one is missing , I tried several time to bind it by pressing the link buttom (link button is only blinking red light not turning yellow or green when pressing) and turning on the transmitter. The light is 2 red and 1 yellow And sometimes solid yellow. Been trying to fix this for 3 days already with all the help I can get from google and the manual
