Abstract
A mounting frame for optical components of a projection television receiver comprises tubular members interconnected to form a skeletal structure. The mounting frame incorporates sub-frames to which the projection tubes, mirror assemblies and screen are mounted. The frame forms a rigid structure which maintains the positional relationship between the optical components in spite of environmental or other changes, thereby facilitating assembly and adjustment of the projection television receiver.
