I have a 2020 built bike, purchased Nov 2020, I had this happen once when the bike was fairly new. I recently went on an interstate trip where half of the trip was a direct 26 hour ride only stopping for fuel and food. I had the screen go blank on me 9 times during the trip. When I got home I had the 30,000km service carried out, the Alternator had also failed when I got home and it was replaced under warranty. I advised the service advisor of the fault with the TFT, there was no faults logged or found with the bike. I'm pretty sure it's not loose battery terminals causing it, otherwise there would be something else logging a fault or other there would be other symptoms. This complaint also comes up on other forums like GS where they have the same TFT.
I feel this is some sort of voltage threshold glitch in the TFT electronics software.
