二、由保护电路故障而引起的“开启难”故障徒弟:如何分析检修因保护电路而引起的“开启难”故障? 师傅:现代彩电绝大多数设有各种各样的保护电路,目的无非是防止故障进一步扩大化,避免更多的元器件惨遭损坏。随着保护电路的广泛应用其保护功能日趋完善,但是事物总有两方面的,保护电路越多越完善,电路就越复杂,保护电路本身出问题的可能性就越
Second, by the protection circuit failure caused by the “open difficult” fault Apprentice: how to analyze the maintenance caused by the protection circuit caused by the “open difficult” fault? Master: Most modern color TV sets with a wide range of protection circuit, the purpose nothing To prevent further expansion of the failure to avoid more damage to the components. With the wide application of the protection circuit, its protection function is improved day by day. However, there are always two things. The more and more the protection circuit is, the more complicated the circuit is and the more the possibility of the protection circuit itself is out of order
