I found out I had two servos fail. Not sure the reason, it occurred during flight training after shutting down the power to simulate a panel failure, then after, powering the system back up. The Garmin people were great to work with and very responsive. They have my old servos and will be examining them for a possible cause. I installed the G5 as my fail safe and it’s a great instrument to have in the cockpit. Very happy with my Garmin package.
