Two G3x touch screens, dual ahars, 307 auto, AOA, 23es transponder, etc. approx 25 hours in phase 1. Up until today, only minor squawks, all corrected. About 10 minutes into today's flight I started getting occasional red x's. Then, everything went red X including transponder and remote radio. Flew home using gtn 650 and ground speed from 650. Radio on gtn 650, which is not part of the canbus chain, worked fine.
On ground, booting up in config mode showed not a single unit had any check mark next to it. Neither red x or green check mark, just blank
The only thing I had done before this flight was pull the two main screens to check a serial #. Pulled both main screens and checked pins. All good. So reinstalled and all units were checking out green in config mode. Took plane up for a shakedown and everything worked fine.
So, my question is likely cause?
Would a break in the canbus chain, perhaps aggravated by engine vibration, cause all units to go red x?
Flying again tomorrow but want to start thinking about trouble shooting if it should happen again.
Thanks,
Tom H.
