Question about Dell UltraSharp 1901FP 19" Flat Panel LCD Monitor
Hi Thanks for your question.
First of all you should check connections. That means using known good monitor cable to get this possibility out of the way. Your problem sounds like Backlight in your monitor went bad. With little knowledge you could possibly buy and replace the backlight yourself and if you are interested in how to do it yourself please click hear to have a look. If not looks like you will need to give your local service a go or buy a new monitor. I hope this helps. Good Luck

Sounds like your backlight has gone faulty, this is a pretty easy repair, however it can be either the inverter, the power supply, or the lamp itself. You really need a service manual, to see how to do it and troubleshoot, exactly locate your fault. Otherwise,all one can do, is swap out, know good for bad, starting with the Power Supply, and working back, as if PSU isn't working 100% nothing else can do.

This must be caused by a bad or damaged capacitor(s) on the Inverter board (power supply board). The only solution is to replace the defective capacitors. To do this, you'll need some electronic tools like soldering iron, soldering wire/paste, etc.. and most of all the capacitors with the exact Unit. You'll need to refer to the one on the board for the unit, it should be written on the capacitor itself as "?" followed by the value. Actually this is related to backlight, but since backlight shows up and you could see the picture for a short period, then the reason is behind the regulators, means the capacitors. If you have idea how to solder or how to remove the soldered components, go ahead and replace them. You'll be easily able to identify them, bulged or exploded or broken.... If you don't know how to use and how to disassemble the monitor, I don't recommend as you might damage other components which will cause another bigger issue. I hope you understand.
If you need further help, let me know.
Thanks for using FixYa.
