2021 Mustang Mach E First Edition, 2016 Nissan Leaf, 2003 Toyota Tacoma, F-150 Lightning Lariat ER
Did you try rebooting the Sync 4A screen?My 15” display failed to startup yesterday morning. Black screen, as if it lost power. But.. it showed the camera images when I shifted into reverse, and the truck was 100% drivable. I did two things, not sure which helped. I ended up shutting the truck down, locking the doors, pushing the button on the charge port several times (in case I messed something up when I disconnected the charger) and walking the keys away from the truck for about 1/2 hour to make sure it went asleep. Bottom line, it booted back up just fine, no problems since.
That would have been my Plan A if I know how to do it! I found some instructions for other vehicles, that didn’t seem to apply to the lightning with 15” display. How is it done?Did you try rebooting the Sync 4A screen?
