③TCP驱动IC易发故障部位图4所示为TCP封装驱动IC及易发故障部位。图5所示为TCP封装驱动IC易发故障部位的故障点及故障类型。图4 TCP封装驱动IC及易发故障部位示图2.液晶面板其他故障现象(1)“白屏”或“黑屏”液晶彩电在背光灯正常点亮的情况下只显示为“白屏”(常亮屏)或“黑屏”(常暗屏)的故障,大多是由于液晶面板失去供电电压而引起的。当液晶面板失去供电电压时,对于常亮(NW)型液晶面板,故障表现为“白屏”;而
③TCP driver IC prone to fault location Figure 4 shows the TCP package driver IC and prone to fault location. Figure 5 shows the fault point and fault type of the fault location of the TCP package driver IC. Figure 4 TCP package driver IC and prone to fault location diagram 2. LCD panel other symptoms (1) “white screen ” or “black screen ” LCD color TV in the backlight is normally lit only show “White screen” (often bright screen) or “black screen ” (often dark screen) failure, mostly due to the loss of supply voltage LCD panel caused. When the liquid crystal panel loses the supply voltage, for the normally bright (NW) type liquid crystal panel, the failure manifests as “white screen”; and
