电视机上出现场偏转线圈断路,为了减少维修成本和用户负担,可不必更换新的配件,而采用“土”法进行修复。笔者所谓的“土”法,实际就是在断路的场偏转线圈上,随意取几个点用断锯条刮去绝缘漆层,每刮好一个点,就用万用表随时测量其到线圈端点的阻值,当发现有两个点分别到线圈的不同端点上的阻值之和,接近正常场偏转线圈的阻值时,用导线将这两个点连接起来,通电试机,如果场扫描出现失真,可通过调 A field deflection coil on the TV set was disconnected. In order to reduce maintenance costs and user burdens, it is not necessary to replace the new parts with the “earth” method. The so-called “earth ” method, the actual is in the field of deflection coil off the coil, take a few random points with a saw blade scrape off the insulating paint layer, each scratch a good point, with a multimeter to measure the end of the coil at any time Resistance value, when found that there are two points to the coil on the different end of the resistance and the value close to normal field deflection coil resistance, the wire with these two points connected, power test machine, if the field scan appears Distortion, by adjusting
