Since Dell monitors are made by BenQ, please look at Dell photo albums.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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.

BenQ FP71E turns off after 2 secs- Logo flashes then turns off


LCD monitors behaving in this fashion more than likely have a faulty inverter. Refer www.lcdparts.net for solutions.

Benq FP71E, No Image Displayed


Try checking the settings in properties for this device to make sure they are as you left them. YOu can also uninstall the drivers for the card and reinstall them to see if that takes care of the issue.

BenQ FP71E 17 - how to open


There are 4 pieces 2 each around yellow invertor transformers.
Check visually for darkened back of the transistor.For reliable testing you need to desolder and test with an ohmmeter.Also check the FET Fu9024 or D10Pf for similiar problems.
What is your actual symptom?

Hi...there,
With AC adapter it's to your left, a rectangle piece. Without, it's under you power supply w/ built-in inverter... the capacitors look like a tiny battery on the side it have voltages size ( example like 1000uf 16v ) Good lucks, have a nice day!

Power but no picture


Try to re-solder the inverter part of the board. You may recognize that part where the 4 connectors from the backlight tubes can be found.... usually the small transformators (sorry, my technical English is not good) have bad soldering eyes after longer use. This may work if backlight turns on for a few seconds, then the power led is still alight but screen goes dark.... the inverter then "thinks" one of the tubes might be defective and turns power off. Hope this helps a little...
