Sorry this is being so difficult Rob, that message looks good except for the lack of the important line.
I've been doing some testing and managed to get your scenario, I'm surprised others were able to update, they got lucky an old eeprom location had a number stored v5 relies on, your's unfortunately doesn't so the controller is in a frenzy it'll never get over.
I attached a sketch to upload to the controller, this will setup all the default values on the controller so it has numbers it expects and actually starts up. After you upload this sketch open the serial monitor and it will say "Start", wait about 5 minutes and it will say "Finished". At that point you can upload v5 to the controller again, and this time the serial monitor will print that ever important line. Then you will finally see the message on the display to update.
If the message doesn't automatically appear on the display when everything is turned on, press the top left corner of display for 2 seconds while the controller is powered and connected and it will reset the display (you can also just unplug display and plug back in) and you will get that message for sure. :)
You are correct the screen is going blank because the back light is turning off, that's because the display hasn't read the eeprom yet to see what the back light level should be so it goes blank, that won't happen when the update message appears.
