Question about Acer X221WSD Monitor
I have an Acer X221W monitor connected to an HP Pavilion a320n desktop. It has been working fine for the last 6 months until yesterday when the screen went dim and then blank. If I switch the monitor off then on the screen shows "ACER" briefly for about two seconds then flickers dimly and then goes blank.
Is the power supply faulty or is it something else?
Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it went dim and blank, you have to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Common problem with that monitor (backlight works for 2-3 seconds) is transormer SPI 8TC00332

One of my clients just dropped one of these things off. It has the same issues, and I took a chance on trying to fix it. To get the rear panel off, remove the two screws at the base of the display, then start prying the case open with flat screwdrivers. It's best to start at the corners, and one-by-one pry apart the compression fit locks (there are about 3 on each side) that hold it together. Once inside the case, getting into the power board it no problem. On looking at the power-video board, I found 3 mushroomed capacitors: two 15V 220uf, and one 15V 330uf. I had no problem finding the 220uf caps in an old monitor, but the 330uf is a really odd duck. I took a chance and put a 470uf cap in it's place. There's a marked improvement, though it's still far from fixed. Where it used to shut off after 5 seconds, it now stays on for as long as 5 minutes at a stretch...but always winds up going black. If I toggle the switch, it'll come back on....for anywhere between 10 seconds to five minutes. I'm still on the hunt for a 330uf cap, or may try to rig a 220uf and a 100uf in parallel. Not a complete solution, but helpful perhaps.

Hello Ching. I have an acer AL1917W LCD monitor, and my problem is the same. When I turned on the monitor for the frist time on the day, it seems to work ok for about 2 or 3 minutes, then it goes black and the power button goes from green to yellow and then green again, and the acer logo appears just the same way as when I turned on the monitor for the first time. And this continues in a cyclic way. Then, the power button goes from green to off, then yellow, then off, and so on, and the acer logo continues appearing and dissapearing the same way.
I have read about some faulty capacitors inside and I think I can remove them and check them with a universal bridge (I have one HP) but my main problem right now is how to remove the back cover. There are not visible screws and the only thing I can see is a hole with a padlock drawed near this hole. I think is through this hole that the cover can be removed.
Any one knows how to remove this cover? Will I need some sort of specific tool to do that? Please, I need your help.
