Dell E172FPb REPAIR TIP

BRAND: DELL

 

MODEL: E172FPb

 

SIZE: 17"

 

PROBLEM: GREEN PWR LED
FLASHES. ABOUT ONE SECOND INTERVALS. NO PICTURE SEEN AT ALL.

 

SOLUTION: ONE (OR BOTH)
2SC5707 TRANSISTORS WERE FOUND SHORT. THERE ARE 4 TOTAL ON THE BOARD. 2 PER CCFL
DRIVER. THESE WORK IN CONJUNCTION WITH ONE ANOTHER, SO WHEN ONE GOES OUT, MIGHT
AS WELL CHANGE THEM BOTH OUT, AS DAMAGE MAY HAVE BEEN DONE TO THE OTHER AS WELL.
WHEN THESE GUYS FAIL, IT USUALLY TAKES OUT THE PF751 FUSE (3A BELL) WITH IT. IN
THIS CASE IT DID NOT. SCREEN WORKS GREAT NOW!
