Everything has been working just fine up to this point (years), but after several months, I wanted to get into flying my drone again so, I charged up my battery, put in new fresh batteries into my controller. I turned on my controller, then plugged in my battery to my Phantom and set it down to power up. At first, only got repeated red lights blinking, so I unplugged and replugged in my battery and powered it up again. This time after it powered up (green light blinking), I went to start the props, but nothing happened. No response at all. It appears that there is no communication between my phantom and controller. Any ideas? Also, I went to connect the phantom to my computer to check out the systems, but there is no communications between the phantom and computer (no lights lit on lower left corner of computer screen). Help!
