My Main Circuit Board Was Changed

Interesting!  I'm told this writing on my Turnigy 9xr says "the main board has been replaced."  I wonder what that means?

BTW, I confirmed it's an ATMega 128, and OpenTx puts 30 models in the menu.  Sweet!

Update: contacted HobbyKing, they offered $20 compensation which was fine by me.  Everything seems fine, and that will be plenty to order a replacement motherboard if this one ever dies.
