读过《家电检修技术》2001年8期6页所载《熊猫彩电检侈四例》一文,原文所述:“行幅减少的故障原因大多是行逆程电容和S校正电容容量减少。”作者经过实践与理论分析后,认为这一提法实属局部有误。正确的说法应该是:行幅不足,与行逆程电容容量减小和S校正电容容量变大有关。又读《电子报》2002年第42期三期所刊《创维CTV8219彩电行幅不足检修》一文中,发现犯有同样错误。原文中提到:“行幅不足的常见原因有:开关电源+B端电压降低、显像管阳极电压升高、行偏转线圈局部短
Read the “appliance repair technology” 2001 the 8 page 6 pages contained in the “panda color TV four cases,” a text, the original said: “The reasons for the failure to reduce the lines are mostly reverse circuit capacitance and S correction capacitor capacity reduction.” After the practice and theoretical analysis, the author thinks that this formulation is a partial mistake. The correct view should be: lack of line width, with the capacity of reverse line capacitance decreases and S correction capacitor capacity becomes larger. Again read the “News” in 2002 42 of the three issue of “Skyworth CTV8219 color TV line inadequate overhaul” article, found guilty of the same mistake. The original article mentions: "The common reasons for the lack of line width are: switching power supply + B terminal voltage decreases, CRT anode voltage increases, the line deflection coil local short
