I swapped a 2021 2500 Tradesman from the 5" screen to the 12" screen. I have all the proper harnesses and adapters, and have made the proper adjustments in the BCM with AlfaOBD. The screen works properly for a little while after a global reset but after a few sleep cycles it will be blank. The backup camera still works. All the hard buttons still work. It plays the radio. The screen is just blank. It does flash for a split second as you move the shifter between gears. Basically it flashes on when the shifter is between positions. Any ideas?
