After 20 min the screen goes black. But, it I hit the AUTO GREEN LIGHT IT WILL TURN ON ONLY FOR A FEW SECONDS. If I let the computer rest for 20min then the screen will stay on for 10-15min and go off again. The monitor is 2 1/2 yrs old. Made in July 2005. I am very disappointed as at my job as used old monitors last 15yrs. I am ready to find an old antique monitor and use that. Could it be any other problem? Thank you..firstname.lastname@example.org
The electrolytic capacitors in the power supply have gone bad. I had the same problem. The caps are not easily replaced unless you are experienced in electronic repair. Capacitor problems have become more prevalent in the last 10 years in many types of electronics.

well i have a dell 22'' monitor and it did exactly the same thing , turns out its a fault with the invertor drive transistors ( these power the fluro screen light ) , i'm in the uk , but i would take it straight back to walmart along with proof of purchase and tell them it dont work and ask for a repair /replacement under warranty
it sounds like a deleted driver? try getting the driver for the monitor, did you loose the Operating system at some point, if so try a system restore to a date when the computer was working properlly prior to the malfunction. It sounds like it restored you to a time before the driver for that monitor was installed.
it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.
although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode
some one else suggested that i remove and reseat the video card
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
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.
How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.
Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4
bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
