Power up after return from shop visit...
Anyone knows the reason?

Had similar case on PSEU once - apparently in the shop, after they finished the work on the unit, they did not go out from the "shop mode". Had to return the unit to the shop, as not possible to control this function on wing.

Thank you for feedback flyday, good to know the fix.
