Everything on my 41CV seems to be working properly with one exception. The LCD module has become blackened at the ends. The left end is the largest area of black....approximately 1/8" wide at the left middle of the screen and then tapering to nearly 3/4" wide at the screen top and bottom. The black on the right side of the screen is very minor. I believe that the amount of black has remained this way for some time... I don't see any continuing degradation.
My questions is whether this is permanent damage or is it related to contact failure between the display module and the circuitry?
