Question about Sceptre X9G-NagaIV 19" LCD Monitor
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.
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?
I have the same problem .
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 .
just started looking for a replacment for mine the closest i have found is around 25 bucks plus shipping wont know if it will work till monday when i can call them to match up the one i have

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.
