Acording to the described sympthom, your 41 has more likely developed the "Display Driver to LCD polymer strip stress syndrome".
In short, there are a couple of conductive polymer strips that connect the LCD itself with the Display Driver board. The whole thing is tightly held together by a couple of U shaped steel frames that ensure appropriate contact pressure.
However, moist, corrosion or aging can lead this contacts to get dirty, worn or loosen; causing the display to behaves like yours: missing segments, irregular opacity or shades.
It can be repaired, but removing, dissasembling and (even more) re-assembling the display is not a trivial task, and chances are that the LCD get broken if it's not handled with extreme care.
Obviously, replacing the whole display is a better option in case you get a suitable spare part
Hope this helps.
