If you ARE ABLE to get any kind of light on your monitor showing that it's got power running to it, try this.
1. Try your monitor on someone else's computer.
2. If you can't do that easily, try pushing the monitor button in for half a minute or so, and then trying it again.
3. If that doesn't work, turn your computer off.
4. Now unplug it! Don't forget this step please.
5. Remove your graphics card if it isn't built into the motherboard.
6. Put your graphics card back in again, carefully.
7. Plug the cables in again, making very sure they are all in the right slots and that they are hooked in soundly.
8. Plug your computer back in.
9. Turn it on again.

You can try skipping 5 and 6 and just going through the other procedures first if you like, and then if that doesn't work, go through the longer process starting at number 1 again, but this time including with steps 5 and 6.

If your graphics card is removable and fits into another slot, you might even want to try that. If you have already tried that and none of those procedures worked, you might want to buy another graphics card from a dealer (preferably one who will allow you to return it within a few days), to see if that solves the problem. Make sure you look at the back of it before buying it to ensure it has all of the plug-ins you need and/or want.

10. If you can't see that there's any power going to it at all and can't feel any heat coming from it after it's been on for 10 minutes, then you know the problem is solely with the monitor and not with anything else so you may have to talk to a technician in person and ask if he feels it's worth repairing.

Note that whenever you plug and unplug the main cable that runs from your computer to your monitor, it's best to shut your system down first to prevent sparks and/or damage to a card or even to a major piece of equipment. I also prefer to unplug my own equipment entirely during thunderstorms because I've known a few people who have blown their entire motherboards this way.

    I sure hope it's not the black screen of death (often a really bad virus or some hardware problem like bad memory or whatever).
    If you've tried all of the things above, and have tried your monitor on someone else's computer (easiest solution) and it worked there,
    try this:

    No wait -- try this first. Try someone else's monitor on your computer. If theirs works on your computer, you will know the problem is with the monitor and NOT the computer.

    If the problem "IS" with the computer, try this:

    1. Reboot your computer.
    2. Hit F5 about 50 times very fast while it's rebooting.
    3. When you get a black command screen with a command prompt, type the following:

    It will check your computer. Be prepared to wait if it takes a long time. If you're lucky it could take long - up to 2.5 to 3 hours. If you're not quite so lucky it will give you a message telling you what the problem is but you likely won't be able to interpret it. You will have to write it all down -- possibly an entire page.

    If you get it going again make sure your virus protection is always updated! Black or blue dead screens are really an unpleasant thing.

    Remember though, before playing with the monitor plugs that are stuck in the back of the computer UNPLUG either the computer or the monitor. Don't plug it in again until it has been hooked up to the back of the computer.

    If you can't run CHKDSK/F either, and you have tried swapping monitors and nothing worked, you will either have to get someone to attempt to remove viruses for you or else install windows again. (You will want to format the entire drive). Then, of course you will have to reinstall everything all over again but don't install any of the other programs until you have put on your virus checker and updated it first!

    Oh, and if either of you have one of those $2.00 real working Windows CD's that you may have purchased from Korea.... well, you could experience more problems. Get an original copy from a recognizable reliable source.

New TV 9 mos old, Won't stay on after power up? Remote or manual turn on, set keeps turning off after 1-2 second green on and brief screen flash.

I would try leaving the TV unplugged for 30mins so the TV can reset itself.
If that doesn't work, your TV should still be under warranty. I know 95% of come with a 1 year warranty.
The most common problem with Sylvania TVs made by FUNAI, the Backlight Inverter board fails to early in life. ( That's the part that powers the screen)
The Tv can't power up the screen and it turns off automatically. Basically called "Protection Mode" so it protects the other parts inside the TV.
