很多情况下,电视机的修理条件非常苛刻,不但缺乏必要的仪器和设备,甚至连起码的元器件都没有。应急修理便是在这种严峻情况下的一种修理方法。应急检修的方法很多,大部分是不需要另加元器件,而有一些特殊情况下的应急修理则必须外加零件。为了讨论方便起见,以下分三个部分对应急检修法进行讨论。一、功能性改变电视机通常都以数百计的元器件组成,虽然它们的规格很多,品种却有限。其中有一些在电路中缺一不可;还有一部分是起辅助作用的。例如有的是为了改善某一性能指标,有的是为了减小干扰,还有的为了实
In many cases, the condition of the television set is very harsh, not only lacking the necessary equipment and equipment, but even the minimum number of components. Emergency repair is a repair method under such severe conditions. Emergency maintenance methods many, most do not need additional components, and there are some special cases of emergency repair must add the parts. For the sake of discussion, the following three sections discuss emergency maintenance methods. First, the functional changes Television is usually composed of hundreds of components, although many of their specifications, the variety is limited. Some of them are indispensable in the circuit; others are auxiliary. For example, some are to improve a certain performance index, some to reduce the interference, and some in order to
