I RMA'd this probablem as well. They asked the usual questions -- try it alone, check the connections, are you using VGA or DVI... blah blah. Eventually they could give me an RMA.
They have customer support via phone on Sundays in the US, which is nice. Total time from calling to RMA was about 20 minutes.

Same symptoms with no display and blinking green light. My monitor had been having a distorted image occasionally and a subtle whack on the side would clear it up for a week or so. I replaced both of the 1000uF 16v caps and both 250uF 25v caps on the power supply. All 4 were bulging before. Powered up and all looks good. Thanks!!

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.

If there is a flashing led on front of the monitor, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1
The internal circuits are jammed because of electrostatic charges
accumulating on capacitors, or because of a wrong voltage read by the
main chip on your monitor controller board. this started the protection
circuit.
2 The protection circuit detected a wrong voltage or a
broken contact, identified an internal fault and kicked in , starting
the flashing light.
If you are in situation one, then the
monitor will reset just unplugging power cord for one or two hours,
sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common
faults that can occurr suddenly are a blown capacitor on power board,
the inverter board powering up backlight lamp has blown, or a fault on
main lcd controller board.
check also the video cable, if the cable
is shorting, or the connector is bad, you can get same flashing state
because of the video cable.
Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact Viewsonic to find out a Viewsonic service point.

If you want to repair at your own expenses, just locate any good qualified repairer.

The problem can be in the backlight inverter circuits, look fo bad caps with bulging tops, look to see if you do have 12vdc feeding the inverter circuits. See some examples of failed monitors here: http://s807.photobucket.com/home/budm/allalbums
