Question about Sceptre X9G-NagaIV 19" LCD Monitor

Montior Repeatedly Shuts Off/Goes Black

History:
First, I purchased this Sceptre X9G Naga-IV back in December of 2005.
I hook this monitor up to my computer via the DVI connection.

Problem:
The problem I am having is that the monitor repeatedly shuts itself off (after about 10-20 seconds), the power buttons are still lit but the screen is completely black as if it is off. I can turn it off and back on and it will come back on but it will then shut off again after the same timing given above.

I have tried hooking the monitor up to another computer of mine (once again via the DVI port) and it acts the same with the other computer leading me to believe this is a problem with the monitor itself.

Does anyone know what could cause the monitor to act this way and how or if I might remedy this?

already know what it is .
its the cfl power inverters which are build into the power supply
easy way to see is let the computer start up hold a flashlight up to the screen you should see your desktop .if so its the inverters/powersupply .

I've had the same issue starting on my Sceptre, it has coincided with a pure bright white screen appearing when I turn the monitor off, and when the signal from the computer is gone (computer off, monitor auto shut off). I've had to unplug the monitor each time I turn it off, and when I turn it back on this black screen (though only takes about 2 seconds until mine darkens).

I've temporarily "fixed" it, it works ok if you just turn it on and off repeatedly, eventually one of the times it turns on it stays normal for as long as I have it on.

This model may have a built in stand by mode separate from your OS command. this is easily fixed buy using the physical buttons on this monitor. other than that, you may have a manufacturing run that has been shipped nation wide with this major flaw in design.

It may have dying power supply due to bad DC filter caps like the 17" version.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor stays black until boot up to Desktop


you use a graphics card as your main output?
and you have onboard graphics output too that you dont use?
if so then you will have to plug your monitor lead into the onboard output socket to see bios. i think you need to go into bios and change which device starts from boot.
it sounds like you have the onboard graphics as your boot device and windows using the graphics card.

Getting the monitor apart


It is clipped on, or there is a hidden screw underneith a sticker or something.

They make these things hard to disassemble for a reason. There is very little you can do one you've got it open. There's almost nothing inside that can be serviced by any normal user.

Hi dgp1952, Check with www.lcdrepair.net if you want a repair. Something is wrong with your backlight or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. Dust can cause the circuitry to heat up faster and put the power supply into Clamp mode. Clamp mode will turn the supply off to certain circuits which may be the reason your display is going black after 5 minutes.
