    I also have the same issue. When I leave the computer and come back, many times the monitor is black and the lcd is blinking blue. The power button will not even turn it off. Only when I turn off the computer does the lcd turn red and allow me to turn off the monitor. After a reboot or two, it works again (sometimes with the Red Gain set to 0).

Check some of the other posts as it is probably just a bad capacitor or two and very easy to fix if you can do that sort of thing. I did and mine is back up and running.

Sceptre X7G komodo II Power light and screen flash about every second. Could it be the blanking circuit?


Look for bad caps with domed tops as shown in my pictures here: http://s807.photobucket.com/albums/yy352/budm/SCEPTRE/Sceptre%20X7G/
should repalce the caps in a set.
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.

Sceptre Monitor P/N X7G-Komodo II displays for about 1 second at a time, then goes black. When I cycle monitor power, I see a perfect display for 1 second. Does anyone have a recommended solution?


When the backlight does not stay on for more than a second, the problem is usually the backlight power supply board failure. Typical failures are blown capacitors, or transistors. A electronic repair shop should be able to fix it.

X7G shows video for 1 second then goes black, any replacement boards available?


Hate to tell you that replacing parts on a monitor would be very hard not only to find the parts but it would be very costly, I would recommend scrapping it and buy a 90$ refab off tiger direct or something, the only thing you can really fix on a monitor is perhaps a dead pixel, other than that its not worth it.
