An electronic visual display system with an integrated general lighting system including an electronic visual display having a housing and one or more lighting devices integrated therewith to provide light to one or more spaces external to the electronic visual display housing. The object has a plurality of alignment marks of which desired positions are known. The diagnostic module estimates the cooling fluid temperature, determines the cooling performance based on the outlet temperature and the cooling fluid temperature, and selectively diagnoses a fault in the cooling system based on the cooling performance and a predetermined threshold. The pressure of the tank may vary from any absolute pressure down to near complete vacuum, thereby all but eliminating the pressure requirement. The bearing element may provide longitudinal guidance to the movable portion in the event of a collapse or reach adjustment.
