Had my PV2 for a week now. Had 1 crash (broke a propeller). Now I go to turn on drone, does it little beeps and 1st few blinking lights from under, but then they (led from underneath) turn off. As if they aren't doing a system check anymore. Lights turning on at 1st boot up tells me the lights work so I ruled that out. The drone won't fly as of now. All batteries are charged up and can't seem to see anyone else with the same issue. I noticed however when I plug in the main battery it no longer blinks while its charging. But pushing the button on the battery for a status update works fine and again putting it into the drone and turning on works. While drone is on I hear the humming from inside and the camera. Any ideas what this could be?
