Hello, New ham here -- just got the technician license less than a month ago.
I have a Yaesu FTM-400DX bought on December 26, 2022.
Today it started to behave erratically basically rebooting itslef constantly. Up for a few seconds, then reboot, and so on. Rest to factory, without helping the problem. Now it is stuck on the reboot screen that says "Yaesu" and my call sign. Cycling power does nothing, comes back to the same screen.
What do I do? Is there a hardware reset? Return to store for replacement or send in for warranty repair?
Thank you all.
