Could anyone shed some light as to why several MP50s have a completely black/blank display. We switched out the entire display with backlights and inverter, front bezel, and small display driver board with no change. These units have been operating for months in a low resource setting with no air conditioning and the daily temperature typically runs near 35C, 95F with usual relative humidity between 50% and 80%.
