A week ago my monitor ( Mag Innovision LT916s ) was working fine. Then one morning when I booted up, the monitor went black, like it went into sleep mode. the light was still green though. When I turn the monitor off and then back on it works for about 2 or 3 seconds then goes black again. If I keep tirning it off and on it will sooner or later stay 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.

It could be two things. 1). The video card is set to a resolution the monitor does not support. 2). The monitor's power supply is bad. You can try to boot into rescue (or "safe") mode, and adjust the video card to a resolution the monitor supports. OR, power supplies usually go bad because capacitors bulge or otherwise go bad. Most monitor power supplies are hard to get, so people typically repair them. If you disassemble the monitor shell, you can see the power supply (where the AC cord goes). You can look at the metallic, cylindrical looking things with minus signs down one side, and if they look bulged on top, you can replace them. You can get replacements at mouser.com.
You have a monitor with a common problem. After a few years some LCD monitors will blown a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he 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 pictues and your monitor should work fine. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, iff so please rate my solution.

It is most likely that the filter capacitors on the power inverter board have failed. I took mine apart and found seven swollen capacitors on the this board, they fail prematurely and seem to be the only thing wrong with the unit. I replaced them and now it is working just fine.
six 470uf 25v electrolytic capacitors and one 220uf 25v Capacitor.
you should not attempt to repair this yourself unless you have some electronics training since there is a shock hazzard involved and also these capacitors will blow apart if they are installed incorrectly (very messy experience).
1. Check the cable connection to your PC. It might be disconnected.
2. If your have more then one cable input on your LCD monitor(VGA or DVI) check if you selected correct input; digital for DVI or analog for VGA.
Hi this is the way how to examine
what's wrong with your monitors. After you turned it on and the screen went black, you have to check that 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. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. 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!! If anything I can help you with, feel free to let me know. Thank
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!
