I had my 440 quit mid-flight. The radio had gotten really quiet for some reason and I looked over to see a blank screen and the AUX button blinking in red. Troubleshooting in flight is stupid so I switched radios and on return, took a look at everything physical I could see. The fans are running and it has power and its a cool day at 82. No booting even in maint mode under a full 14 volts and no issues with the CB's. It has worked flawlessly since I had initially brought it up three months ago after a settings error. Now this. I have called Tech Support this morning and they said to send it in for evaluation and repair. Has anyone ran into this before and do you have any idea what has happened here?

Thanks.

The Pilot’s User Guide lists 5 possible causes:

Terrain Pull up

Obstacle Warning

Pull up

Unit Overheating / Unit unreliable

Low Volts (< 9 volts)

Put a voltmeter on the bus and check the voltage.
