彩电开关电源具有功耗小、效率高、稳压范围宽、保护电路灵敏可靠等特点。但彩电开关电源种类繁多、电路各异、故障现象多变,给维修人员带来很大困难。有时因个别元件的变质而出现的慢性疑难故障更使维修人员头疼。有时要赔上几只电源开关管和行管,使维修成本过高,严重时会烧坏集成块乃至显像管,造成不可估量的损失。这里给大家介绍一种经济、实用的方法,可以给彩
Color TV switching power supply with small power consumption, high efficiency, wide voltage range, sensitive and reliable protection circuit and so on. However, a wide range of color TV switching power supply, different circuits, fault phenomena change, to maintenance staff great difficulties. Sometimes due to the deterioration of individual components and the emergence of chronic difficult problems even more maintenance staff headache. Sometimes lose a few power switches and pipe line, so that the maintenance costs are too high, will seriously damage the manifold and CRT, resulting in incalculable losses. Here to introduce an economical and practical way, you can give color
