I was thinking about that on the way in to work this morning, perhaps you meant the LCD speedometer display. Usually the "DIC" refers to the cluster of telltale lamps above the HVAC control unit.
The 90 and 91 are compatible as far as I know. There are 2 #194 bulbs behind the panel, if it is just not lit up, but the LCD segments are still working.
If the LCD segments are not working, but the backlights are still illuminated, then I'd pull the cluster and check the connections for the LCD, it's a series of pins that insert into a ribbon cable. You have to remove the clear lens, then the analog gauges, before you can remove the LCD.
A little clean up of the contacts with a mild abrasive like a fine brass brush or a pencil eraser might help.
It is possible that you might need a 90 specific unit, but I really didn't think there was any difference until 92.
