行扫描部分的任务是向行偏转线圈提供水平扫描的锯齿波工作电流和向显像管提供各个阳极的高压和次高压及灯丝电压。行扫描电路发生故障也常常会导致无光栅的故障现象。笔者的目的是学习根据故障现象确定检修流程,通过测量数据确定检查的走向。

Line scan provides horizontal scan sawtooth working curent to line deflection coil and to each anode of kinescope high pressure and high pressure and sub-filament voltage.Line scan circuit failure often causes no symptoms grating.Most fault-free raster scan line is caused by the power supply or failure.The objective of this paper is to learn according to the fault phenomenon sure/repair process,and to determine theinspection through the measurement data.
