Question about Dell 1703FPs 17" TFT LCD Flat Panel Monitor
You may have bad backlight inverter board (shorted transistors, transformers, need test lamp to verify), or worst case the lamps assembly (need lamp tester to verify).
You can check and see if the power supply is putting out the 12vdc for the inverter board first and go from there.
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.
