Ag Express still seems like a good repair place as long as mother Deere has not locked them out of repair parts like they did on a 50 series dash cluster.

JD dealer suggested this place where they got repairs done also. It's Canadian so not sure how crossing borders and tariff stuff factors in.

They do show repair services for your model and unit but probably need to contact them for actual prices.
