One's flashin it's power light, the other's image is green-ish
I have 2 of these monitors. One of them is displaying the same issues as described here. The other monitor's screen is green-tinted (very much), which makes my work as a webdesigner ''rather hard''. I tried several cables and several computers, but the problem appears the second I turn it on, so I'm assuming the hardware is faulty.

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.
I hope this helps, if so please rate my solution.

With any monitor, check the following to determine if the issue is MONITOR related or COMPUTER related.
1. Verify the monitor is receiving power - use a known good power outlet and plug it into the monitor
2. Samsung monitors have a light on the power button - are you getting any color light from this? Orange means it is in "stand by" mode and is waiting for the PC to send it a signal. Green means the monitor is getting a signal from the PC and the monitor is on.
3. With the monitor on, press the buttons on the monitor to bring up the OSD (on screen display) that changes the monitor settings. If you have a green light on the power button and press one of these buttons (AUTO works best), this will display the monitor adjustment options on the screen.
If you see the on screen adjustments, your monitor is working and the issue may be with your PC. Move the monitor to another PC and verify the monitor is working correctly.
IF you don't see anything on the screen and the power light is green, the monitor has failed.
This could be the lights that illuminate the screen have failed (something that happened to my Samsung Syncmaster monitors after about 6 years of use) or the screen has stopped functioning. In either case, replacement parts are hard to find and a monitor swap is likely.
Acer produces a number of LCD computer monitors. Acer's monitors range from 17 inches to 27 inches. Some monitors offer wide-screen viewing, embedded speakers, high-definition visuals, and various display connection ports. Acer computer monitor problems include common issues such as dead pixels, error messages, and blank screens caused by incorrect connections. Some reviewers have also detected image problems with DVD playback on some models.
"Input Not Supported" Error Message Acer computer monitors such as the G24 may issue an "Input Not Supported" error message when users set the display resolution too high. The G24's maximum display resolution is 1920x1200 with a 60Hz refresh rate. Maximum resolutions vary according to the specific monitor model and according to the capabilities of the computer's video card. b> "Input Out of Range" b> Some Acer computer monitors may report an "Input Out of Range" error message due to incorrectly set monitor refresh rates. Much like the display resolution, each monitor also has specific monitor refresh rates with which it is compatible. Blank Screen or "No Signal" Error b> Like other monitors, Acer computer monitors feature color-coded power indicator lights. If the power indicator light shows green, the contrast or brightness levels may be set too low and should be adjusted via the OnScreen Display. If this does not rid the monitor of a black screen, the monitor may be experiencing hardware failure. The "No Signal" or "Check Cable message" may indicate a problem with the monitor's cable connection with the video card. This error may also appear on a blank screen backdrop if the monitor is plugged into the incorrect port on the computer or if the computer is frozen and needs to be rebooted. Faulty power cords or outlets may cause the screen to be black and to show no power indicator color. b> Image Issues b> Some review sites such as CNET have reported problems with streaking and ghosting during DVD playback on some Acer computer monitors such as the AL1931. (A "ghost" is an identical offset image as the primary or desired image.) Unstable or unclear image issues may be caused by incorrectly programmed VGA timings or incorrectly installed monitor drivers. b> Dead Pixels b> Dead pixels and sub-pixels can cause a variety of display enjoyment problems. Acer will only accept returns on LCD computer monitors that have "more than four (4) defective pixels per million pixels." Further, the central area of the monitor may have no more than one defective pixel. Acer does not differentiate in warranty terms between pixels and sub-pixels. Hope this helps.
You can try to do the monitor self test. Monitor Self Test: 1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD. It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.
The flashing green light and no display usually means that the backlight circuit has failed. You can verify this by shining a flashlight on the dark screen and see if there is an image. If there is an image, then the problem is the backlight circuit. Often the problem with the circuit is that the transistors burn out. There are sellers on ebay that sell repair parts kits to fix these monitors if you are handy or you can bring to to an electronic repair service to have it fixed.
I had the power on and off cycling issue described in another post and when I reassembled the projector I forgot to plug the two wire plug back into the power board. The power light flashed. I removed the top cover and plugged it in and the projector is now working perfectly.
This seems to be issue with the Computer not the monitor. Check the monitor with different computer or you can check the monitor also. For this take out the monitor cable from the tower and turn on the monitor alone, if you get any message on the monitor screen it means that monitor is fine. Try this and let me know.
you need a green CRT thats whay you have the white kind of concave lines with the green screen. You can try adjusting the green screen control but you need anew CRT ( tube) the speaker cover has two plastic plugs that get removed on the lower edge os the grille which covers the two screws that hold the grille on. If you need more assistancr or where to get a green CRT let me know as I have a link that has some green and red Tubes for your model.
Try replacin a new display card. If it is fine working.ok
If not try fixing for cold solder in the video section.
I suggest video section according your report the light green LED lighted that shows the power section is doing fine.
Try another power adaptor.
Check the delivered voltage and go get a universal power adaptor that has a switched for varios voltages and a number of connectors.
Simply match connector to the voltage switch.
