Source to repair JD digital tach?

I’m in the process of refurbishing a pair of JD 4850 tractors; one of them has a very faint LCD display, and the selection buttons no longer work. I opened the gauge and found the ribbon cable to the board has come loose.

Does anyone know of somewhere I could ship this gauge off to for repair?

Thanks

so, I've decided to try and fix this myself.

I've got the gauge opened up, and the ribbon cable for the buttons on front goes to a connector, not soldered, so that's an easy fix.

I've ordered some LCD polarization film online and currently have removed the old polarization film. We'll see how this goes.
