Question about Dell E173FP 17" LCD Monitor
I have an E172FPb that initially would come on with a normal display for a few seconds and then go dark with no image in the background. I diagnosed two shorted transistors (Q759, 760 - 2SC5707). I ordered 4 of these from LCDRepair but replaced only the two bad ones (leaving two for backup). I also resoldered the 4 transformers near the four transistors. I can now see and image in the background that stays as long as the computer is on. Should I have replaced all four transistors even though the other two tested good? Could it now be that my backlight tubes are bad? Can the backlight leads be tested for voltage if they are disconnected from the lights? If so, what voltage should I get? Any help would be greatly appreciated. Dave
