Re: acer al1916w (with pics)
thanks for the help.
I plan on ordering tomorrow. 6 of the black caps and the "sideways" brown one unless it isnt needed? what about the 2 small brown ones in the bottom middle of the first attach?...

mosfets with multi on 200
mosfet, pin ohms
a, b = maxed out on 200 all 3 pins (upper right corner)
1-2 1-3 2-3
c = 128.5, 0.1, max
d = 125.7, 0.1, max (both of these bottom right corner near the bad caps)
e= maxed out on 200 all 3 pins (bottom left corner)
trying to measure the ones that maxed out @ 200ohms lead into the 20k-20m range slowly rising.
mosfet a, b = 40t03gp
mosfet c = sbt100
mosfet d = sbt150

Re: acer al1916w (with pics)
I'll get a read on the mosfets in a bit. What ohm reading makes them bad, and what if 200 ohms isnt a high enough number to read them?
I can solder basic stuff, though more used to doing wires.
I can probably match up numbers on a diagram, dunno how well i would be at the 50 step diagnosis/volt/ohm checking though but willing to give it a shot if it comes to it....Leave a comment:

Re: acer al1916w (with pics)
testing mosfets is basically out of my league. is it possible to test them without removing them, with a multimeter?
i found a few places talking about how to do it, but nothing for dummies.
the way where you charge it up with a multimeter and then short 2 pins made sense, but you have to remove it for this way?
also, my monitor does work after it "warms up," i'm assuming that means the fuses are ok...Leave a comment:

3 black caps look bad. should i replace all of them (including the smaller brown ones?)
the big cap looks ok, and i guess generally isnt replaced?
also have seen lots of "smps" chips / TEA1532 on other acer monitors go bad. my monitor doesnt seem to have one of these. I see "dap8a" 8 pin, and "bit3713" 14 pin chips and not sure what they are exactly.

Re: acer al1916w going bad
I looked some but most seemed to be monitors that didnt work at all, and got really confused with all of the comments saying it could use different power circuit boards etc.
I'm still using the monitor and hoping for a quick fix before things go worse...
thanks for the reply. i'm hoping it's just that and not something else
I have a multimeter and soldering iron but neither are great quality. I'm hoping to just replace the normal caps and hope that it fixes it.

acer al1916w going bad
Monitor recently started repeating the logo screen and not showing the desktop. After 5 minutes or so of doing this, then it will turn on and work normally.
A few days later, it would repeat the logo for a while and then the power light would go orange and fade in color and the monitor would go black. I could unplug and plug back in the power, then it would repeat the logo screen and work (eventually.)
Keeps taking longer and longer to turn on, but once it's on it stays on...
Is this bad caps, or something else? It's an acer al1916w from march...
