徒弟:师傅!在彩色电视机中,“三无”故障率是最高的,都有哪些部位能产生“三无”故障? 师傅:在彩电中,能产生“三无”故障的部位大多发生在电脑电路,电源电路,行扫描电路及保护电路。徒弟:怎样才能快速判断故障部位呢? 师傅:关于怎样判断故障部位及检修方法,我们通过几个实例来说明。徒弟:我这有一台日立CTP—237D型彩电,出现“三无”故障,在开机瞬间能听到机内发出“吱”的一声。
Apprentice: master! In color TV, “three no” failure rate is the highest, which parts can produce “three no” fault? Master: In color TV, can produce “three no” failure occurred mostly in Computer Circuits, Power Circuits, Line Scan Circuits and Protection Circuits. Apprentice: How can we quickly determine the fault site? Master: How to determine the fault location and maintenance methods, we illustrate through a few examples. Apprentice: I have a Hitachi CTP-237D-type color TV, there “three no” failure, the machine can be heard instantly issued a “squeak” sound.
