Hi there I have spent some time trying to fix my DAC-19M005 BF REV 01A in my AL1916W monitor.
Schematic location
I recapped all the electrolytics other than the large 400V (CE106) even the small guys (CE108 and CE107)
The FETs aren't shorted
My fuse blew and then reblew when I dropped in a 2A replacement.
I measured some locations:
Across CE106 = 170VDC from a 120 V wall source, which seems crazy to me.
Across CE102 = 5V
Across CE101 = 15.1V but the schematic states a 16.5V level there.
Across C101 = 15V but the schematic states a 13.8V level there.
And there is a crazy noise, it goes: "silence...buzz...tick" about every second. I couldn't isolate it though ( I used a rolled up peice of paper)... i've never had any luck doing that.
There are tonnes of posts on this board and i have made it through many threads but not all.
