Not sure i have a solution to this problem yet, but i believe that i am encountering a similar problem, but may have perhaps noticed something that you did not.
when you power on, and the screen comes on for about 2 seconds...does it do this every time? meaning...does it come on for at least a second every time?
if so...look a little more closely...are you sure that the screen is going completely blank or is the backlight going off. i believe the problem i have is the backlight is going off, and if i look closely in the right light, i can see that the screen is still on, it is just darkened.
unfortunately, i have no solution to this...if anyone else reading has a solution, i would appreciate hearing it...but i figured this might help your troubleshooting a little

I have been having this same problem for about 8 months or so now. This is by no means a fix, more of a temporary work around. When the problem occurs I just disconnect the monitor cable from the video card and then plug it back in. It usually takes about 3 times and then the monitor stays on. I get the problem all the time, like once a day or once every couple days. I'm to cheap to actually fix it though.

Hello,

It bothers me, when a user comes to a Fix It web site like this and I have to suggest you send it in for warranty replacement or service.

But, we can check a few things first just to be certain is isn't the circuitry turning itself off due to a problem on the power or signal board. First look at the back cover of your panel for a pull out or unlock release to relese the back panel that covers the power plug and VGA socket. Remove that if needed. Examine where the power plug inserts and the VGA cable attaches onto the flat panel chassis. On the power plug, see that it is firmly inserted. I'm almost certain you've checked this already but when you have it firmly in place do you notice any wiggle room or wobble of the plug in its socket? If so, that would be a problem of the mount to the power inverter board. Next, check that the VGA cable is firmly attached by using a small flat head screw driver to tighten down the cable into its plug. Then, remove the VGA cable and check each pin on the plug to see that there isn't a loose one or one that is bent. If you find a bent one, do not attempt to starigthen it yourself. Take it to a tech shop where they have tools for this.

If both the the power plug and VGA socket seem fine, lets examine the function of the power button next. This is what we call a momentary on/off push button, meaning you momentarily close a circuit when you push the button and this impulse energizes the power to the panel or de-energizes the power board. You want to check that this momentary button is not sticking in, but fully releasing. You can most easily assure this is this case by flicking the button. Push in on the button from the edge using your fingernail and letting your fingernail slip over the button. If the button appears to fully extend back up when you do this than it is not sticking in the down position and the monitor is not turning itself off as a safety feature.

Your monitor usually is turning itself off as a safety feature when after turning it on it turns off a few seconds later. It does this to protect itself and your investment. So, if after doing these things you find no irregularities, let me know and I'll assist you in getting warranty service.

Regards,
Worldvet

I can vouch for Rooster's work-around of unplugging and plugging the monitor cable a few times. Also, turning it on and off while randomly hitting the auto-adjust seems to work after several iterations. It's all very annoying though and would like to know the root cause. The behavior is so predictable though that it has got to be a software issue, IMHO.

SOURCE: monitor goes black 1 second after coming to full screen

I have 2 systems with the FPD1500 monitor. They worked fine until I applied

SP2. After SP2, they will not start. They come on OK, display the Windows

XP splash screen and then go into sleep mode when the system starts the

proper display mode before the Windows XP login screen is displayed. If I go

into safe mode and uninstall the video adaptor and restart the system, it

will start properly. After it comes up, it finds the video adaptor and

installs it and the session proceeds OK. I can reset the resolution and

number of colors to 1024x768 and Highest (32 colors) and things look fine.

However, when I restart the system, it hangs up after the Windows splash

screen and the monitor goes to sleep.



If I put it into VGA mode, it will come up OK. But once I change any

resolution or number of colors, it imediately goes to sleep.

I would appreciate any help you could offer.

Hello,

The power supply in the unit has died. This is a very common problem with this series of monitor after 2-3 years of use. If you can solder then you should be able to do the repair yourself. Check out our step by step repair guide posted on our site at: www.ccl-la.com Our guide gives parts values and location information as well as how to open the unit up. If you don't feel like doing the repair we also offer repair services, see our web site for details.

SOURCE: flashes on then goes black

The green light only lets you know there is a valid video signal reaching the monitor. If the green light was not "on" your problems would possibly be within the pc itself. Something is not holding the circuit for the backlight "on" thus going black. Suggestions are: 1. Take it to get it repaired (if not under warranty) Hyundai carries a 3 yr warranty on this monitor. Website provided. 2. Buy a new monitor http://www.hyundaiq.com/Eng/Customer/CusSvc/Csvc.asp

SOURCE: ACER AL1914 LCD Monitor goes black but green light stays on

The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the inverter(power plug). Parts that go are the backlight ccfl's, behind the plate, and parts of the inverter, ie capacitors, all three take a bit of power from the inverter. The self test check that all the lights are ok and the inverter is ok, else it switchs off, ie if 3/4 light work it will switch off(my own case), hence the on chech error then off, However sometime there are stages of on/off ie on/ but no screen display, if that is the case the following may be of help...if you put bright light at an angle close to lcd can you see a windows shadow, text icons etc, ie still logic power passing,then .... (from a.n. other) after two weeks searching I finally find doctor living stone http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent
the takening the case bit off is like opening your wallet a second time after buying a new LCD, but you must! smallest two screw driver's flat headed, practice using two pennies stuck together()with your fingers after, one little () move and inch and {} again, with the case , it does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip inside!] also note the bright light test to do first to see if can see a windows screen , and that capacitors are one for a number of things that a make a inverter work! there a transistors as well, given that however, to replace all the capacitors on my inverter, was 11 capacitors, cost me $11 (uk ebay) and already had the iron and solder. So only cost me me $11 to try and see but no luck , still fun and I still can see the screen for 2 sec' at a time plus I have a spare set of caps now in the event that the new one do go burst! you have to laugh really, what next , a new on/off button, as you work though the whole inverter mmmMMMMmmmMMMMmmmMMMMTim Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not wellMMMMMMMMMMnnnnnnweek later land sight mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the inverter. If it went out over a slow period of time (flickering etc..) I would bet it is the lamp.replaceing the lamp should be pretty challenging. as that requires complete breakdown of your LCD, extraction of your dead lamp, and soldering in your new lamp... but I would like to say that I it did this after realizing it's 2 x kitchen strips inside [========] with wires that can connect back to the inverter with out any desoldering(ie kit assembly/dis) with the outter case remove (glass plate safe away) I could reconnect and see that 3/4 were working (i!i hardcard ) cause the inverter to switch off after a secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a 1/3 of the price ! the market as drop out there, hope the inverter does not miss the length, or the screen out put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR MONITOR

Screen goes black after 2 seconds


This could be one of two problems, the light in your monitor has a loose cable, or the light is dying. I have seen cold cathode lights that are about 10-15$ to buy and many instructions on putting them in yourself.

Solution 2, your cable is loose on the back of the monitor. Make sure you have the screws tightened on either side of the vga or dvi cable, both on the back of your monitor and on the back of your computer or laptop.

Monitor goes blank less than a second after turning on.


I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

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
