D180 black screen and starts again in flight

[filser]

Dynon D 180 sn1494
Since few months the following event in flight:
Suddenly black screen
Then blue screen with Dynon logo
then gray screen with message "attitude recovery" in red
and after one minute the D180 works again properly.

My device has the internal Dynon battery working fine.
I have checked all the main power line. No failure.

Any idea ?
Should I return the D180 to factory ?

Thank you for your advice.

So the gray screen and attitude indeterminate message are expected when the unit is powered on in-flight. The in-flight restart, obviously, is not normal. Yes, please contact our repair department for further assistance with this issue: https://www.dynonavionics.com/contact.php
