"And this one is just right" ~ Goldilocks
It's good to have someone you trust. But I could see the scenario Tal experienced. A dealer would run the diagnostic, shows bad display, orders display, wait (how long?), installs new display (includes plugging it in firmly), and, bam,... it works!Indian/ Triumph of Knoxville on Clinton highway. Rob is the head mechanic there and I trust him %100.
It may not occur to them that your current display is fine and just isn't fully plugged in. If it were me I'd go down and check myself, but if you trust the dealer I'd ask them to see if pushing the plug in brings your bike back to life.
