My Zenmuse H3-2D is not working anymore. It used to work fine, but now is unresponsive and I can't figure out why.
Also the Phantom's GPS is not working and I am unsure if that is a related or separate issue. When connected to the Naza software assistant, it shows no option to enter GPS mode from the transmitter (just ATT-ATT-ATT), nor can I turn on "failsafe return to home" feature because it says it need GPS. When in GPS mode on the transmitter, the Phantom LED continues to blink yellow - confirming GPS mode is not active. Also, I can't switch between GPS and ATT modes 10 times on the transmitter to toggle compass calibration - likely because I'm not actually switching into GPS mode.
Everything is connected in the same way it has been in the past when it worked (roughly 30 flights). Perhaps the Zenmuse or PMU has been fried, which is preventing the GPS from working (since GPS runs through those units).
