If the effect is uniform over the entire display
area you can probably rule out damage to the LCD
elements and crystal material itself. Most likely
the voltages going to the LCD are no longer correct.

Since this "faded" over time my guess would be any
caps in any inverter stages. That would be typical
from the ESR faults etc that occur with caps over
that time period. Check any electro caps in it,
even the circuit mount ones. The surface mount
caps in 10uF seem to fail a lot, they ooze a
fishy smelling liquid. :o)
