A long time ago I remember Paul Opitz saying that Uniden could repair any brand scanner dependent on availability of parts and one of the parts that was an exception was the LCD display.
That's going to be hard to find, you may put ads out looking for a non-operative pro 96 that you could cannibalize. My Pro 96 display is still bright but it hasn't been used in years, and maintained it in the leather case for many moons. Perfect condition.
