Good afternoon guys, I got a Phantom 2 at Christmas it was been working fine, i haven't used it for roughly one month. I have fully charged the battery and inserted it. When I hold the power button in for two seconds I get 4 Green lights 1 Red and it goes off, once or twice the Red LED began to flash and then went off. The motors won't start, none of the LED lights are lighting up and its making no starting noise. I'm quite concerned. I'm new here so any advice or help is hugely appreciated.
