My Phantom 3 Standard powers on, but I’m experiencing several issues. Only the battery light comes on and the link light , and while the motors make the usual ‘beep-beep’ sound when powered on, the red link light stays solid and doesn’t pair to my controller at all. The strobe indicator lights don’t turn on at all. The drone won’t connect to the remote controller, and when I try to connect it to my phone, there’s no telemetry or camera feed. Additionally, the gimbal doesn’t power on. I bought the drone from someone who mentioned it had been in storage for a couple of years. Could these issues be caused by a faulty battery, or is there another underlying problem?
