Question about Acer AL2423W LCD Monitor
My 24" Acer monitor has been down for a few weeks now. every now and then after not using it for a while it will turn on and display everything but the next time I turn it on (showing the green power light) it doesn't display anything at all. Sometimes I'll see a little flash from the right of the screen and see part of the "acer" that shows up in the middle but usually not even that. I opened it up and all the capacitors seem to be fine. Could this maybe be a fuse issue?

Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

We had the same problem with the 17" we bought in Aug. Sent it back for repair. Acer sent it back without fixing the problem. Started doing it again in Nov. This time I called a supervisor and they sent me a new monitor. Well yesterday it started doing the same thing. You can fix it temp buy unplugging it and holding down the on-off switch for 30 seconds. Please let me know if you have a better fix.

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

I had one with the same problem. All the capacitors in the power supply were fried. If you're good with electronics, you can pull it apart and replace them (about 8 bucks in parts) or take it to someone who is.

use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.
please rate me and give me a fixya! if it helped.
