Screen on monitor suddenly went black. green light is now orange. tried re-booting. nothing works.
SOURCE: No display, green light on ViewSonic VP201b 20.1 LCD
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.

Possibly either the backlight lamp or its associated power supply has failed.
Power buttons (mostly LEDs) have constant availability of low voltage (for some other circuits too) otherwise they wouldn't 'wake up' on command from a computer as some do.
The blackout could also be due to a failed main power supply so the incoming video is no longer being processed.

I have the same problem with my VX922 as do MANY others. The problem seems to be caused by leaking/bulging capacitors on the circuit board. The only solution is to replace the faulty capacitors either on your own (which is fairly easy if you're good with a soldering iron) or send it to Viewsonic and have them fix it.
