我想可否从以下几方面考虑这个问题: 1.由于该彩电的电路在形成批量生产之前是经过设计者及有关人员审核的,并且经过实验是切实可行的,关于这一点可以从该彩电出厂前的检验和在用户家中工作至出故障前得到证实。也就是说该彩电的电路没有问题。 2.如图1所示,电源变压器次级经二极管半波整流后,一方面给电解电容C1充电;另一方面经L876给行电路等电路供电。由于电源的振荡频率接近15625Hz的行频,振荡频率较高,在每一赫兹的变化
I would like to consider this issue from the following aspects: 1. Since the color TV circuit before the formation of mass production is reviewed by the designers and the relevant personnel, and after the experiment is feasible, this point can be from the color TV factory before The inspection and the user’s home to work before failure to be confirmed. In other words, the color TV circuit is no problem. 2. As shown in Figure 1, the power transformer secondary half-wave diode rectifier, on the one hand to the electrolytic capacitor C1 charge; the other hand by L876 to the circuit circuit power supply. As the power of the oscillation frequency close to 15625Hz line frequency, high oscillation frequency, changes in each Hertz
