Question about Acer AL1716 17" LCD Monitor
Hello everyone i have a Acer 17 inch monitor that when plugged shows no power what so ever. The typical green light for power does not even show nor do the switches to turn it on work. I have completely taking apart the monitor to see if i could at least find a bad resistor or capacitor. I would appreciate any advice as to where should i start making judgment if the main 450v capacitor is receiving power tested by a mulitmeter?
As someone suggested the 3 10 volt 1000uF caps are bad. You can
indentify them because they're puffed up on the top and therefore
blown. Replace them withj a 25 volt cap 470uF or larger and away
you go. I did 4 of them in 3 hours. The case snaps apart
which is the hardest part. them remove all the screws you
can find, unplug the display from the board, remove the rest of the
screws holding the power supply board down, and look for the puffy
caps. Cahnge them and put everything back together and away you

It's a switching power supply ! Make sure all 3 fuses are OK then if you see caps are swollen, that means caps are weak, leak or defectiv. Try to change all caps then regulator IC.
Fuses are F101, 2 black fuses near CN101.
I suggest to replace C123 because it's a feedback caps.
