Re: Black Screen Dell E1910Hc 19" LCD
I saw it, D907 = SRF1060 Schottky Rectifier, I tried to test using digital multimeter set to diode, from center-right (2-3) = 0.143V; from center-left (1-2) = 0.144V

Re: Black Screen Dell E1910Hc 19" LCD
Rtech,
D902 = 0.435
I cannot find D907 on the board, I measure these two diodes:
D901 = 0.422
D905 = 0.435
CN902 = Blue/Black = 3.2VoltLeave a comment:

Black Screen Dell E1910Hc 19" LCD
Can you please help me on how to troubleshoot this monitor?
When I connected the power, there's a blue power led indicator but the screen is black only and there is no display or shadow picture.
I tried to open and I did not see any busted electrolytic capacitor, I tried to search first on the internet and what I found as the same model with my monitor to replace the electrolytic capacitor.
I replaced all the capacitor but I don't have the same voltage rating, what I do is, I used 680uF 35V as replacement for 680uF 25V and 470uF 25V as replacement... -
