例141康佳T2806型彩电故障现象:经常烧爆电源块STR-S6309,有时还损坏电源块“!脚开关管发射极电阻R911和F901。分析与检修:测C911容量下降过多时,输出电压迅速上升,从而烧坏STR-S6309。在这种情况下,一般采用代替法判断C911是否损坏。在本例中更换C911后试机,故障消失,说明C911
Example 141 Konka T2806 color TV Fault phenomenon: often burn the power block STR-S6309, and sometimes damage the power block ”foot switch emitter resistor R911 and F901 Analysis and overhaul: measured C911 capacity drops too much, the output voltage quickly Rise, thus burning STR-S6309.In this case, the general method to determine whether the C911 replacement damage. In this case after replacement C911 test machine, the fault disappears, indicating C911
