Backlight problems


Yes,

If the capacitors in the power supply are bulging that indicates that they have failed internally and need to be replaced. That would cause the back light inverter to shut down just like you are having.Replace the capacitors and you should be good to go.

Have a dell e177fp monitor. When I power on it only displays for 3 seconds and shuts off. Green power light remains on.


You need to check the voltages and components in the power supply/inverter board first. It should have 5vdc for logic and 12~16vdc for the backlight innerter circuits.
There are three version of the boards for this model.

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, 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.

Disconnect the monitors plug. Unplug the power cord. You may not have to do both, but it reset mine and it works fine now.
