雷击彩电故障,一般分强雷击和弱雷击两种。强雷击损坏的彩电,由于雷电电场和能量较强,进入电视机后,大多造成纵向和横向双重破坏,往往损坏的元件较多,不但损坏雷电侵入源头的电源,高频头部位元件明显烧焦、爆裂、电路板烧断,而且雷电还侵入电视机其他部位,造成耐压较低的二极管、三极管、集成电路等元件大面积损坏。检修时应先更换和修复明显损坏的 Lightning color TV failure, the general points strong lightning and weak lightning two. Due to lightning electric field and strong energy, after entering the TV, most of the color TV sets damaged by lightning strike often cause vertical and horizontal double damage, often resulting in more damaged components. This not only damages the power source that the lightning enters the source, Jiao, burst, the circuit board blown, and lightning invaded other parts of the TV, resulting in lower voltage diodes, transistors, integrated circuits and other components damaged in large areas. Repair should be replaced and repaired obviously damaged
