彩色电视机的整机调试是在各部件(通常分调谐器、中放、行扫描、场扫描、解码、视放和电源等几部分)都已调好的基础上,进行总的调试。是老化试验前的最后一道工艺。在黑白电视机中,如果各部件的调试都符合要求,且整机接线无误。那么,一般“开口”后,只需做下列工作:调节行场扫描的有关电位器,使图象中心、线性、幅度符合要求;调节亮度电位器、对比度电位器、音量电位器均能起作用,并符合质量要求;总机电流也符合要求。对于大偏转角显象管还要进行光栅的畸变校正。但是,彩色电视机的整机调试却要麻烦得多。除了上述工作以外,还必须进行消磁,色纯度调节,会聚调整 The whole set of color TV set-up is debugged on the basis of all the components (usually divided into tuner, middle set, line scan, field scan, decode, video and power supply). Is the last test before the aging process. In black and white TV sets, if the commissioning of all components meet the requirements, and the whole wiring is correct. So, the general “opening”, just do the following work: Adjust the field scan of the potentiometer, the image center, linearity, amplitude to meet the requirements; adjust brightness potentiometer, contrast potentiometer, volume potentiometer can work , And meet the quality requirements; switchboard current also meet the requirements. For large deflection angle kinescope also need to carry out the distortion correction. However, the whole set of color TV debugging is much more troublesome. In addition to the above work, but also must degaussing, color purity adjustment, convergence adjustment
