Kymco Like 150i Noodoe - No more Display after changing Battery !!

[Jays 150i Noodoe]

Please Help !!!
I switched out my battery with no issues (I really do know what I'm doing), and upon starting the scooter I get the display screen to flash the Kymco Noodoe logo (in color) for about 1 second and then the screen goes blank gray.  While riding around about every 2 minutes the screen will again try to boot and shows the color Kymco Noodoe logos, but then just goes gray again !!   I've seen this same question 3 times in other forums, but unfortunately they are all unanswered ?

I guess nothing in the owner's manual regarding changing the battery.
Wonder if this is a dealer fix? Reflash something?
This would be a good question for a cyclepedia.com tech  via opening a service ticket.
Me? I'd try phoning a few Kymco dealers. Or several....
