2.由行阻尼二极管击穿而引起的“开启难”故障徒弟:据我所知,绝大多数行管内部已包含阻尼二极管,所以行管损坏故障也就包括了阻尼二极管的损坏。师傅为何又单独提出行阻尼二极管,请举例说明之! 师傅:你说的不错,绝大部分行管内部含阻尼二极管,但一些彩电(如熊猫3625型 TDA两片机等)行管(BU508A)内没有包含阻尼二极管,同时,电路也较特殊;该阻尼二极管与可控硅保护电路联系在一起,因
2. “Difficult to open” caused by breakdown of the line damping diode Disciple: As far as I know, most of the inside of the run has already included a damping diode, so the failure of the running control also includes the damaging of the damping diode. Master why you put a separate line of damping diodes, please give an example! Master: You said good, most of the tube inside with damping diodes, but some color TV (such as the Panda 3625 TDA two machines, etc.) line management (BU508A) Damping diode is not included, at the same time, the circuit is also more special; the damping diode and the SCR protection circuit together, because
