Screen turns on for a slight second perfect image then goes blank, if i pull power out and back in as soon as its got power it does it again, perfect image then blank, although the screen's light is green. I can press the power button off and then off and again it starts then cuts out... 1 screen same problem on 3 pc's. Cause of issue was when i plugged in my TV to the S-Video and it was turning on and then my screen cut out and has been doing what i noted above since, I think it must be in a perminant sleep mode or somthing since ive never had a problem with the monitor before hand

If you are going to DIY 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/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Vc6 luna, A visit to YOUTUBE should help you understand how you will investigate and possibly repair your very old E173FP display. The Switch mode power supply will be first thing to visually inspect for "bad" capacitors. If still require assistance, then return to fixya and read and follow link in the fixya profiles of "budmrtn" "12fixlouie" and leave additional info for us to read in a comment to this response. 12fixlouie
