匈牙利TA5309电视机系集成电路与晶体管混合的24英寸黑白电视机。该机采用了泵电源电路。现介绍一些分立元件损坏引起的故障修理经验: 1.烧保险丝: 烧保险丝既与泵源有关也与外电路有关。最简单的判别方法是断开T 601泵管集电极。在C 610电容两端加接25V的直流电源。如果电视机正常,故障在泵电源中。反之,则在外电路中。由泵源电路引起的烧保险丝常见的有泵管T601击穿,整流二极管D601-D 604部分击穿等。在更换上述零件时,应注意它的性能、参数等。如T 601在更换时要用性能比较好的泵管,如BU326,也可用 Hungary TA5309 TV system integrated circuits and transistors mixed 24-inch black and white TV. The machine uses a pump power circuit. Now introduce some damage caused by discrete components failure repair experience: 1. Burning fuse: burning fuse both with the pump and the circuit is also related. The easiest way to determine this is to disconnect the T 601 tubing collector. Add 25V DC power to both ends of C 610 capacitor. If the TV is normal, the problem is with the pump power supply. On the contrary, in the external circuit. Burned fuse caused by the pump circuit common to the breakdown of the pump tube T601, rectifier diode D601-D 604 part of the breakdown. In the replacement of the above parts, we should pay attention to its performance, parameters and so on. Such as the T 601 to replace the pump performance better, such as BU326, is also available
