Hello everyone, i have an old acer monitor "AL 1916W"
it was totally dead but after i replace some bad caps now the led turns green and red when it's in sleep mode.
but the picture at all no backlight or a dim picture in the LCD.
i just wanted to know how can i test the backlight and the lcd...
I have this circuit built, and the first batch of 6 pieces all worked.
Now the second time, I made 4, and only 1 works, the others all do the following.
When the voltage goes below 16.2V, the output drops to 7.8V and something buzzes softly. The voltage then after a bit, does go down to zero...
