My confidence in Dynon was shaken yesterday. Straight and level, in VMC, my single HDX display suddenly went black.
It came back a minute later with "system event 3" message - then immediately went black again.
Came back a second time - lasted for about 5 minutes, then went black again.
Came back a 3rd time and functioned normally to landing 15 minutes later.
I have uploaded the diagnostic files to Dynon.
People on the Dynon forum say this happens and is sometimes related to USB devices.
I had the Dynon wifi adapter and the Dynon USB drive plugged in at the time.
serial number is greater than 35,000 and I am running the new 16.4 software that with the wifi bug resolved.
This dynon setup has about 5 hours since new.
I think Dynon maybe having low level USB driver issues with their new hardware (driven by EE component shortage):
1. Service bulletin May 6, 2022 - https://dynonavionics.com/bulletins/support_bulletin_050622.php
2. Other very recent system event 3 - on dynon forums https://forum.flydynon.com/threads/system-3-event.14632/#post-85227
3. Removal of the USB port on the D37 connector on the new displays (SN 35,000 and above?) because "it caused more problems than it was worth"
Has this happened to anyone else? for, me this the first time in 4 years of flying behind Dynon. I do fly occasional light IMC - which I am now re-thinking.
I hope Dynon can give me a solid response and resolution.
