Replacing the back light?

Are you sure that is the problem?

I didn't see any display with a broken back light. It's more likely the inverter driver is the issue. A back light is assembled with the display and it's really difficult to replace it.

If you confirm that is the inverter the problem, here is a link that explain how to fix it: http://josepino.com/?howto-repair-dell

Good luck

My E172FP went out and the monitor on/off light is blinking green.


It had shorted out transistors in the inverter circuits, that will be the first palce to look.
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 DELL 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.
