Abstract
In a rear-projection TV system in which the image is generated by an optical engine and projected through a mirror towards a diffusion plate screen, picture quality adjustment is undertaken at the optical block level to reduce the distance between the adjustment device and screen and thereby improve production throughput in the dark room in which the adjustments are made.

A TV adjustment system, comprising:
- a dark room in which a TV including a screen can be disposed to perform adjustments thereon;
- at least one adjustment lens couplable to the TV for making adjustments and decouplable from the TV prior to vending the TV;
- at least one feedback signal generator for generating a feedback signal;
- and
- an adjustment computer receiving the feedback signal and responsive thereto adjusting the TV to establish projection uniformity on the screen, the feedback signal generator being positionable closer to the TV in the dark room owing to the adjustment lens than the feedback signal generator otherwise would be without the adjustment lens.
