各类报刊杂志已多次介绍关于屡损“行管”的原因,如:主电源电压过高、逆程电容容量减小、偏转线圈及行输出变压器损坏等,都会使“行管”多次损坏。本人最近在修理一台长虹 B2115彩电时,多次损坏“行管”却又是由另外一种原因引起的,现介绍如下,供同行参考。故障现象:“三无”。经查发现“行管”击穿。为防止还有其他故障,拆下“行管”,首先接上假负载对主电源 Various newspapers and magazines have repeatedly introduced on repeated loss “governed” the reasons, such as: the main power supply voltage is too high, the reverse capacitor capacity decreases, the deflection coil and line output transformer damage, etc., will make “governed” many times damage. I recently repaired a Changhong B2115 color TV, repeatedly damaged “in charge” but is caused by another reason, are presented below, for peer reference. Symptoms: “three no.” The investigation found that “in charge” breakdown. To prevent any further malfunction, remove the “governs” and first connect the dummy load to the mains
