Look for bad caps and solder joints.
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 HP 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.

Se198wfpf lcd does not stay on screen briefly


It could be the high-voltage inverter board, I case of a faulty backlight (one of the tube flickers) the board would protect itself by powering off. Try changing one of the CCFL tube.

Yes you got badcaps!!! www.badcaps.net examples of what they are and what they can do and this is one of them. U/You can change out these caps and see if it fires back up again.
