彩色电视机行输出变压器损坏后,可直接用原型号替换;若无原型号件代用时,可按以下原则进行代换。1.代换行输出变压器使用的主电源(+B)电压值应与原行输出变压器接近。2.代换行输出变压器的高压输出应与原行输出变压器相同或基本相近。3.代换时行输出变压器的磁芯尺寸或磁芯柱截面积应与原行输出 Color TV line output transformer damage, can be directly replaced with the original model; if there is no substitute for the prototype, the following principles can be substituted. 1. Replacement line output transformer main power supply (+ B) voltage value should be close to the original output transformer. 2. Replacement line output transformer high-voltage output should be the same as the original output transformer or similar. 3. Replacement when the output transformer core size or core column cross-sectional area should be output with the original line
