SOURCE: Acer AL1916W 19" LCD Monitor '' no power''

There was a busted fusible coil in series with the main line supply. Changed it with an ordinary fuse. There are available voltages for 5V and 12 volts but still there is no power indication on the panel and never turns on. I checked the backlight but no output power. the system control has power supply of 3.26 volts. What really the problem of this unit?

This is not a monitor problem, it's normal behavior. The monitor does this when it's turned on but no signal is coming from the computer. The solution is to turn off the monitor when you shut down the computer, and turn it back on next time you start it back up. The simplest way to handle this is to get a switched surge-protector strip and plug all your computer system into it (computer, monitor, printer, etc.). Then after the computer shuts down you flip one switch and everything is off. It's also protected from power line problems, and that's always a good idea.

Look for bad caps just like other failed monitors as shown in my album first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

mazricool, Will monitor do same strange things when connected to a different "known-good" computer other than YOUR'S ??? What is it that your unit does that you don't like about it? What is the pc operating system that you are using it with. Try installing monitor on different pc first. 12fixlouie

My acer al1916w displays the image for 3 seconds then goes black


Sounds like your video card. Check to make sure it's connected properly. If so, check to make sure it's properly seated to *********** board. The possible issue could be the card is connected enough to display the picture, but not enough to communicate with the monitor to stay on because it has an active feed. Best of luck fixing it

Black screen after a year of use


Sine a flashlight on the screen and check for a dim image. If you see a dim image the back light needs to be replaced. After doing that you will want to try using another monitor cable and see if that helps. If it doesn't with the computer on and the monitor on disconnect the cable from the computer. If the monitor shows a no signal error the graphics card needs to be replaced.

Monitor colors are not displaying correctly


Hi, At the worst it is a blown monitor, but have hope. 1st try a new or known good lead, between monitor and PC. 2nd put monitor with own lead on good PC. if 1st works = result. if 2nd and monitor is same, suspect monitor, however, if 2nd works ok on other PC, then look at ur vid card. Either way, this test sequence should save you some $. Be lucky.

Hi,

My living room monitor faced the same issue before.

I called up Acer, and they fixed the power LCD board in the monitor.

Do not buy a new one yet, unless the warranty is over.

Acer AL1916W 19" LCD Monitor Blacking out


This is not a setting or driver issue! The best way to determine this is to connect the monitor up to another device to see if the same thing occurs! If it does then your backlight is in bad shape and it is starting to go bad. It will generate enough power to display some images, but when it continues to be on for a certain peirod of time it goes black. This is common when the backlight is starting to go bad!
