作为应急修理,该文的思路以及试验是可以的,也是相当不错的。笔者也曾修理过数台根德A1814型彩电,该机的一个常见故障就是水平一条亮线,即TDA2655B烧坏。市场上TDA2655B的零售价很高,本地市场达80余元一块。TDA2655B损坏后,笔者分析过较多的场输出块及代用电路,觉得用TDA2653A代换最为合适,首先是价格低廉(市场价也就十几元左右)。较TDA2655B来说,只有其四分之一左右的价格,如果邮购的话,一只TDA2653A只需4.2元/块,实在是太便宜了。其次是可以直接代换,根本不需要附加
As an emergency repair, the idea of the article and the test is possible, but also quite good. I have also repaired several sets of Germany A1814 TV, a common failure of the plane is a horizontal bright line, that is, burn TDA2655B. TDA2655B high retail prices on the market, the local market of more than 80 yuan. TDA2655B damage, the author analyzed more field output block and alternative circuits that use TDA2653A substitution most appropriate, first of all, the price is low (the market price will be about ten or so). TDA2655B compared to only about a quarter of the price, if the mail order, a TDA2653A only 4.2 yuan / block, it is too cheap. Second, you can directly replace, do not need to attach
