故障现象:一台长虹C2192A型彩电,呈显”黑屏”,但有伴音分析与检修:据用户反映,该机场输出块(TDA3653B)已损坏两块,由于有伴音,分析认为开关电源基本工作正常,检修重点应在行输出电路和显像管电路。
Fault phenomenon: A Changhong C2192A color TV, was “black screen”, but there are audio analysis and maintenance: According to the user, the airport output block (TDA3653B) has been damaged two, due to the sound, the analysis that the basic working of switching power supply , Overhaul should focus on the line output circuit and CRT circuit.
