Hi all,
I got an Acer 1916w monitor here that has some problems.
Model Number: AL1916W A
Version: AL1916W Abd
I replaced all of the caps that were mentioned to be replaced.
My computer recognizes they monitor being plugged in. When I plug in the power to the board, the Power LED light and screen flashes, I can see the CCFL's both flash a bright white when looking at the back of it and it does this just as the power LED goes off.
Measured the voltage at the big 400v cap and it only registers at 67v. What voltage should the cap be at when everything is working properly?
Measured the voltage at the pins to the video board and two of the pins are at 5v and one at 13.8v
The top Mosfet has a slight brown tint to it right where the pins enter the board.
I'm a newbie when it comes to this stuff, but I would really like to get this monitor running as I like it. I do electronics stuff like this for a hobby and nothing more, so I don't have any test equipment other then a basic volt meter with resister check and continuity to it.
Any help would be greatly appreciated and if anyone has the power board schematic with what voltage should be where then that would be helpful too for me to look over.
Not sure where I should go from here.
Attached is the power board pics top and bottom.
Thanks again for any help.
Voltage at the Mosfet's run at around 43v across all 3 pins on both of them.
