修理彩电遇到电阻变值,电容漏电,电感开路时,用三用表测电压和电阻大都容易判断。在高频电路中人们十分重视电容的作用。在低频电路中的电容一般取值范围很大,容量的变化对电路的工作影响不严重,因而人们往往忽视对电容的检查。笔者曾因遇到因电容容量变小造成的故障而走了不少弯路,现介绍给读者供借鉴。飞利浦 20CT605 彩电的光栅自左向右逐渐变
Repair TV encountered resistance variable, capacitance leakage, the inductor open circuit, with a three-meter measuring voltage and resistance are mostly easy to judge. People attach great importance to the role of capacitors in high-frequency circuits. Capacitance in the low-frequency circuit in the general range of values, the change in capacity on the work of the circuit is not serious, so people tend to ignore the capacitor check. The author has encountered a lot of detours because of the smaller capacitance caused by the failure, is introduced to readers for reference.
