My ‘07 does this on a regular basis. Pretty easy workaround was going into service mode and then powering off. Display always comes back. ***Service mode:*** with vehicle off, press power ***WITHOUT*** foot on brake. Hold INFO button down and turn lights on/off (3) times. Release INFO button. Service screen should pop up. Press power again (***no foot on brake***). Display panel should light up. Press power (***no foot on brake***) to turn off vehicle. Works on mine every time…
