    After two years of use, sudenly it started to fail. Every time i start my computer the display starts for a few seconds and then it goes out (black screen). The first days it operated normally after i performed a few "on and off" cicles, but now does not stay on (with image) any more, (no more than a few seconds).

    I hope the solution of changind the capacitor works. If so i will post my results.

    I have the same problem... Have installed a brand new battery with no change. Closing the lid for a few secs will help sometimes... otherwise have to shut down and restart.

    monitor goes black (just very very very dark! not really turned off i think...) and then turns off (probably the power saving feature) and stays with orange light.. turning off and on (usually a few times) should make it work again..

    you can see when it works if you see the AOC logo show up when turned on.. if not it usually just displays a picture for a millisecond and then darkens again.

    the number of times you need to turn it on and off varies from 2 to 50+ .. once i had to sit half of a day without any results..

    btw: taking the AC cable out of the power socket doesn't help..

    Gateway FPD 1730 LCD, screen goes black and the power button is still green. I turn power button off, then on, then screen is back on.

    Some times I have to do this several times the first hour of use?

    I took my monitor to the technical support, where it could be repaired by replacing some part of it. The problem seems to be related to the background light on/off turning mechanism, that works similarly to fluorescent tube lamps, I think. The monitor worked fine for one year until it began to fail again. In resume, the monitor has to be repaired/maintained aprox. once a year in order to work fine. This time I´ll try to find the way to fix the monitor myself, because the cost of mantainig it is quite expensive. In the long term buying a new monitor is cheaper than repairing LM729 periodically, unless you know how to repair it yourself. If someone has a clue about this issue, please post it.

    Same monitor - AOC LM729 - same problem. I sent it in and it came back with the identical problem. What kind of technician could repair this? Electrician? TV repairman?

    i have a hp 1730 monitor that shows a black screen when turned on

    Same problem here - my AOC will start up fine, then suddenly will dim, then go completely black. The power light stays on, and eventually switches to orange for standby mode. If I power cycle it, it works for a few minutes at best, and then it's back to dimming and going blank.

Chris had the right idea. I had the same problem with the f1703. It was just a bad joint. the 1730 is much diffrent then the power circut of the f1703. I do not know if it is the large capacitor. I would like to know where the failure is.

Does power button lights? If so then first unplug from monitor while on and plug back in. Do this about 3 times. If no difference then you have to open back and replace big size capacitor and look for some other caps bad. This only if power light up. If completely dead then first look for blown fuse or loose connection at the power plug inside.

Why does screen go black after a few seconds

Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Black screen

The problem could be in the Monitor, Computer or Cable. Did you try to connect another monitor or can you try to connect another computer (maybe a laptop) to that monitor?
It's important to understand where to start.

Dell 1704 monitor goes to black screen after one

Hi my name is Rain.
Ok so that im clear on the problem. your monitor will come on but in a matter of seconds it goes to a black screen?
If this is the problem. The answers you seek will most likely
be in your video card.
Try this test:
  • Unplug monitor from the computer.
  • Turn on monitor .
  • Look for monitor self test screen.
If you see the monitors self test screen then your problem indeed is
the video card . You will need to replace the video card inside of the computer.

You must repair monitor or bay another.

ViewSonic 19" flat screen monitor goes black - intermittently

There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,

Monitor flashes on then goes black.

I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.
