随着有线、无线电视的迅猛发展,早期生产的只具有八个或十二个预选器的彩电已远远不能满足要求。解决这一问题的最好办法就是为这些彩电加装遥控装置。加装后不仅预选的节目增加,而且彩电的所有功能均可遥控,既方便,又经济。笔者选用瑞康牌080型遥控系统为近百台彩电进行了改装。本文以加装这一遥控系统为例,谈一谈改装的技巧及装后故障的排除方法。 装前检查 加装之前务必对电视机的各项功能进行全面的检查,特别是AFC功能将决定自动搜台的质量。对于有故障的机子要先排除故障再着手改装,以免留下隐患。 改装技巧 1.连接线的线头要短一些。原配套提供的排线线头都剥得较长,应先把它剪短至约Zmm再焊接,以免碰到其它焊点造成短路。
