I just went through this with my EX the week before Alta ceased. They sent one the dealer that was cosmetically damaged (I cannot see a thing wrong with it). As they were out of stock and on back order.
Yours looks just like mine. The LCD itself is cracked. I did take it apart and it has Alta printed all over the board so there’s nothing generic about it or any clue of who may have made it for Alta. When you replace it with a new one it has to be connected to an Alta computer at a dealer and flashed other wise it will display “test” and the bike will not run. It is possible that an Electronics tech could replace the LCD only if you had the LCD. That’s a long shot IMHO. You would want someone skilled at board level repairs.
I made a mount from aluminum and moved the display behind the handle bars where it’s a little safer from harm.
I was told the display was $399 retail and I paid about $270 for the one with cosmetic damage plus $120 to have it flashed. It was 4.5 hour drive to the dealer.
I feel your pain. I hope Alta reopens or datadog finds a source for you.
p.s. if you want pics of the mount I made PM me.
