You started the tractor before the screen had booted up? If so , then it's good chance your card is done....lost a 600 in our combine and the tech said that starting before screen boots up will mess with the voltage and fry the boards.
Never heard of that. You can start the machine without waiting for the display to power up. If the display powers up first, it will likely lose power when you crank the engine, which will mean you may have to shut off and crank again to get proper communication with all controllers.
I would agree that the card is likely the problem.
