I have a devterm that i ordered in april 2022. I had never been able to use it after assembling it. A lcd screen was sent then a main board after the lcd did not solve the issue. The mainboard was installed and it still does not work. I have an expensive doorstop and dont know what to do at this point.
I have reassembled it multiple times with same result. I have used batteries and usb c connector. The same result. There sound like a fan running but no video on lcd screen or external video screen using hdmi adapter.
Anyone have suggestions??
