Thanks, K4WH, for your suggestions. I looked up how an LCD actually operates, and am wondering if perhaps the voltage to it might be a bit low. From reading, it seems like the voltage is what causes the liquid crystals to polarize and block light. So, maybe my voltage to the display is sagging, rather than the display itself failing. Next time I get access to that radio that is something I will check. Thank you.
