That just happened to me, installed the new module and it worked fine for the first couple of flights. Reconnected a fresh battery and no display on the receiver. Plugged in my old OLED Fatshark module and it doesn't power up either. I flicked off an email to FPVfurious and the supplier of the module and pointed out that there were some problems with the module shorting out if pressed in too firmly and damage to the goggles as a result. Waiting to hear back from either or both to see what next steps are.
