I have a Gateway FPD1730 LCD Monitor with a messed up display. See photo - looks like all horizontal lines, can't see any real image, almost looks like static. I suppose this could be a LCD screen issue, but since I don't have one to swap in I wanted to get your opinion. Could it be a board issue where it's getting a bad signal from the board to the LCD? Or is it simply a bad LCD screen?
All caps look OK physically - nice and flat.
I measured voltages coming from the power supply/inverter board.
Pins labeled and measured as follows:
12V: 13.63 in standby, 12.23 ON
12V: 13.63 in standby, 12.23 ON
ground: 0
ground: 0
5V: 5.02
5V: 5.02
ground: 0
[blank]: 0
[blank]: 0
PWR: 4.68V and I think I saw this one vary, not sure
Bright: 1.41V
[blank]: 1.41
Are the PWR and Bright voltages correct? What might the problem be?
Thanks for your help!
