My Acer 221W goes into sleep mode and won't stay on

I've had this monitor about 2 years, I think...and all of the sudden it comes on for a second (green light on) and then it turns right back off (amber light)...I'm assuming sleep mode (since it retains power). I have switched the power cord as suggested by local retail store...but no fix.

SOURCE: monitor doesn't work

I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode. If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead. Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.

SOURCE: Monitor problem

Hi, I used to repair a monitor from Dell. You might have to check what wrong with your monitor when it went back 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 broken lamps and it is very easy to replace. But the most important part is you need to know how to teardown the screen. . 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.

Hope this help you to examine your monitor. If there is anything I can help you with, feel free to let me know.
Thank you,

SOURCE: Monitor goes black but green light still on.

The problem with the Mag lt916s is that it is made with cheap capacitors. If you are interesnted it is a cheap and easy fix. Open it up, which is the hardest part. And replace the six 470uf 105 degree 25v capacitors and maybe even the smaller 220uf one next to them. You will see a bump on the top of bad capacitors most of the time. There are some videos to watch on Youtube showing you how to make the repair.
Good luck

SOURCE: Microtek 997M monitor doesn't stay on...

The inverter is the most common item to fail on a LCd monitor. Capacitors usally fail the most. Are the tops of any of them popped up. If you had any shorted transistors the fuse would probably be blown. Usally labeled F1. I would replace all the capacitors first and go from there. Capacitors are cheap.

My monitor won't come out of sleep mode

when the computer enter the sleep mode, it is possible that the computer remove the check mark from this output activation.

When you have multiple ouptut like a internal LCD and output on a monitor, when going into sleep then waked up, laptop reactivate the internal LCD without reactivated the secondary monitor.

you could need to go in desktop property and reactivate the secondary monitor with the check mark listed : Activate.

If you only have one monitor but still a dual output card or two separate video card same thing can happend. try to connect the monitor on the second VGA or HDMI output and see if the video goes there.

then reactivate your secondary output and make it principal.

Does also happend when your computer is connected to a UPS power and your monitor is directly on the sector. (laptop issu also)

if a brief power outage arrive then the monitor shut down (no power) and the computer continu, as there is no monitor on the output any more Windows will automatically deactivate this monitor. when power goes back, this output is no longuer providing video. I suggest putting the monitor on a UPS as well.

Monitor Problem

I fixed the problem by acquiring a recovery disk that booted me into the bios screen and the screen came on. I then changed the settings, I still don't know why it happened in the first place though!

Thanks anyway though

Monitor stays asleep

Check in the BIOS and see what your monitor settings are.
Did you change the sleep mode or power off mode? What do you do to make it come back on? Sounds like it might be getting too hot and/or going bad. Try it on another machine and see what it does. Also try another video card because the video card could be going bad.
