Re: Dell E172fpb

I had similar problem after replacing shorted Q759 & Q760. No power in backlight circuit. I traced the problem to an open Q757. Q757 turns on Q761 which powers on the IC751 and that controls the backlight circuit. Q757 gets its turn on signal from the video board. After replacing Q757 my "other" transistors blew again so I may still have replace transformers or try something else.
Hope this helps!
