在彩色电视机的维修中,无彩色的故障较为常见。要维修此类故障就必须要对各种彩色解码电路的信号流程有所了解,掌握一些检测的关键点。下面对几种较为常用的彩色解码IC的信号流程和有关功能脚加以说明。
In the color TV repair, achromatic failure is more common. To repair such failures must have a variety of color decoding circuit signal flow to understand some of the key points to detect. Here are some of the more commonly used color decoding IC signal flow and related functional foot to illustrate.
