从康佳“T”系列(P2908T)彩电场输出电路原理图(见图4)来看,场输出块N401(STV9379FA)的正(V+)、负(V-)供电电压分别是:(1)由“行变”T402⑤脚→R422限流→VD404整流→C424滤波→N401②脚(V+);(2)由“行变”T402⑨脚→R426→VD405整流→C426和C427滤波→N401④脚(V-)的。另外,STV9379FA的正相
From the Konka “T ” series (P2908T) color TV output circuit schematic diagram (see Figure 4), the positive (V +) and negative (V-) supply voltage of the field output block N401 (STV9379FA) ) “T402 ⑤ pin → R422 current limiting → VD404 rectification → C424 filtering → N401 ② pin (V +); (2) by the” line change "T402 ⑨ pin → R426 → VD405 rectification → C426 and C427 filter → N401 ④ feet (V-). In addition, the positive phase of STV9379FA
