Question about Sceptre X7G Komodo II 17 in. Flat Panel LCD Monitor
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.

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).
