Supra SA screen doesn't want to turn off.

[SONIC]

Well new one on the lake yesterday, the center screen doesn't want to turn off.
Key off the screen stays on until the battery switch is killed and then it works as normal for a bit until it decides it doesn't want to turn off again.
Seems like it's not communicating with the ecu correctly but when the key is on everything displays correctly.

Any ideas short of take it to the dealer?

Sounds like a reserved capacitance that is keeping the relay open. Sounds like an ECM replacement in the Vision system is in your future.
