例1:华强三洋HPC-2195型彩电,小信号处理集成电路为LA7680。遭雷击换高频头,自动搜台正常。接收看状态闭路信号VL段中央一台、中央五台无图像、无伴音,满屏杂乱网纹,位置不对。过几分钟后中央五台转为正常,但中央一台始终失常。试验几次重新搜台过程,
Example 1: Huaqiang Sanyo HPC-2195-type TV, small signal processing integrated circuit for the LA7680. By lightning for high-frequency head, automatic search station normal. Receive the state closed-loop signal VL central one, five central no image, no sound, full screen messy textured, the location is wrong. After a few minutes, the central government turned to normal five, but the central one has always been abnormal. Test several times to re-search platform,
