Check input settings, whether DVI mode is selected.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Can I assume (?) you re-tried firmly checking each cable connection and the power supply is soundly in place including checking the fuse in the plug That's all I can suggest as the things I would do if in your shoes.

Dell Monitor 2001FP Blank Screen


From your description your backlight is going out. The fluorescent light when it begins to burn out tries to draw too much power. Your inverter is sensing this 'too much' power draw and shuts down power to the back light. Replacing the backlight is the most technically difficult repair of an LCD, and most repair shops don't even offer this service. I recommend that you sell your LCD 'AS IS' on eBay or a similar website. The Power board and the Control Board are both usable parts that can be easily salvaged from most Dell Ultrasharp monitors.

It's probably your dc power supply.

Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.

I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.

I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.
