SOURCE: monitor doesn't work
I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode. If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead. Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.

while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.
Occasionally this will not work for me, but if I repeat it it normally works
Hope this helps - my problem is intermitant so it may be different to what u guys have

Usually this type of problem is due to a faulty electrolytic capacitor on the monitor's power supply board or the inverter board that powers the backlight lamps. If you have a soldering iron and some technical skill it's possible to repair this yourself, if you can determine the bad component. Look for a capacitor with a domed top, or what looks like corrosion or leaked fluid on the top. If you replace the capacitor with one of the same rating and type (in volts and microfarads (uf)) it may fix the problem.
The backlights are usually not the problem in this case, I've fixed dozens of monitors and it has always been a faulty capacitor.
If you are willing to try this, there are lots of resources on the internet that will provide instructions for how to do this. Replacment capacitors can be purchased (usually $0.50 or $1 each) from many electronics suppliers and on eBay.
Good luck, happy repairing!

I have two broken VP201 monitors with different symptoms. One was black screen green light - like yours. The other was purple speks flying all over the screen., purple tint.
I swapped the power supplies and display boards, both monitors had original problems. I swap the inverters and the monitor which was black screen now appeared to work okay - but slightly pink and the monitor which was purple speks is now black screen.
I would therefore assume that both my inverters gone, one being on it's way out. You probably have the black-screen case.
