If the power indicator light from green then turn to red with no display, check the power supply board which may have leak or bulged capacitors. check also weather your vga cable is good, if no signal the monitor will turn to off.

The problem may not be the monitor. Acer AL1714 is known for its weak power supply unit. Unplug power supply from monitor. If the green light on monitor comes on but goes out quickly, the power supply is the culprit!

SOURCE: Monitor stuck on black, menu buttons not responding

It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.

SOURCE: Dell Monitor Not Working

well if the status of the LEd on the monitor is amber(orange) & the system is running on a on board video card & not a Add-on video card... it is a possibility the the integrated video card ot the mother board might have gone bad... either contact a local tech or the tech support for the computer...

also unplug the monitor cable from the system tower & then if you see that there are the bars moving which say monitor self test on... means tht the problem is with the video card or the mother board...
since the system is running on a integrated video card...

starmaxpc, Yeah, at least part of your switch-mode-power-supply is working! That's a good sign. Go visit these sites and see if you could do same. http://forums.pcper.com/showthread.php?t=452974 and pkrobot.freehostia.com/LCDRepair5.htm also try http://www.net/blog-entry/specialed/2008/12/31/how-to-fix-your-broken-lcd-monitor then get back to me if you intend to repair this DAYTEK LM190. Also there is a ton of other stuff that relates to failed power supplys in LCD monitors. Even YOUTUBE has a whole ton of stuff! Even disassembly videos of lcd monitors!

Monitor flashes logo and then turns black.with red lights on
Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.
