Was a super-duper scary experience and don't know what caused the SC screen suddenly ,without giving any audial or visual warning , turn into pitch black and left me in condition with have no control of my MP2. Story behind, it was a calm night flight in an area densely surrounded by high buildings and nearby passing elevated light railway viaduct. International Airport was 500m away but I was still in the safe zone and authorization recorded on the SC before takeoff. All firmware and batteries were updated before the flight and calibrated the compass as well. Finally, RTH point confirmed before the take off. At about altitude 110m, literally few meters horizontally away from the take off point, SC screen suddenly turned into pitch black. I could only see the charging status led was on. After having a short panic attack, I managed to press RTH hard button on SC then forced to restart the SC. SC screen turn on and M2P was also descending to the home point preciously. What I realized, there was only 10 satellite locked at that moment. Assume should be at least 13-14 min.(??) So my simple question, what could be the cause. And how to avoid or minimize.
