** Is this a problem with the computer chip (or ice/water control board) that controls the display, or is the problem likely to be something else? **
It may just be power is not getting to the door. Has anyone checked the power connections to the door?
Other than that, systematic testing of the dispenser unit would likely be required to determine the cause of the failure. There are no 'usual' suspects that I'm aware of.
BTW. In case you're interested, there is a repair manual available for that fridge model:
