hello, my dji n3 ag died when connecting to dji assistant2, i saw that the flight controller had no lights on, the pmu only flashed a solid red led, I think it's a software or hardware malfunction, what should i do...

Hi Thanu, please check if the power supply is normal, since PMU is solid red, you may need to check and make sure that the power supply is the direct-current power supply within 3S -12 S, check if the positive and negative wires are connected correctly. Thank you.
