电源电路若损坏,就应根据其故障表现和指示灯的状态来判断故障部位,从而对等离子电视机的电源电路进行故障检修。在进行实际检修之前,首先应了解等离子电视机电源电路的故障表现。一、电源电路的故障表现电源电路作为等离子电视机中的重要电路,若发生故障,其故障表现也较多,如整机不动作、开机“黑屏”“、花屏”等。1.整机不动作若等离子电视机的电源输入电路或整流、滤波电路出现故障,势必会造成电视机整机不动作的故障,主
If the power circuit is damaged, it should be based on the performance of its failure and the status indicator to determine the fault location, so as to plasma power supply circuit troubleshooting. Before the actual maintenance, we should first understand the plasma TV power circuit fault performance. First, the performance of the power circuit failure Power circuit as an important plasma TV circuit, if there is a failure, the failure performance is also more, such as the whole machine does not move, boot “black ”, “Huaping ” and so on. 1. The whole machine does not move If the plasma TV’s power input circuit or rectifier, filter circuit failure, is bound to cause the TV machine does not operate the fault, the main
