COURSE CONTENT OUTLINE

Introduction to the course. Review of test equipment.
Discuss the principles of color, the limitations of the human eye and the use of these limitations in the formation of the color video signals which are added to the black and white transmition.
Study the current method of creating, adding, and transmitting the complete color video signal. The Block Diagram will be used extensively to explain the formation process.
Presentation of a complete Block Diagram of a color TV with emphasis on those blocks which are used to process color signals and show them on the CRT.
Block by block analysis showing the circuitry of each block with emphasis on troubleshooting.
Presentation of Tube Circuit theory to give students an ability to recognize and trace signals through tube type equipment.
Block by block analysis of each circuit previously done but now in Tube format. Again with emphasis on the troubleshooting methods needed to isolate any fault.
Demonstrate the methods of testing, removing, replacing a color picture tube.
Discuss the procedure used to align the television before returning it to the customer. Includes: power supply adjustments, grayscale, linearity, purity, color convergence.
Review and final examination.
