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.

Update: I paid a bit more attention to the latest occurance of the problem and the monitor did get slightly brighter before blanking out. Also, it has a barely audible high pitched sound just before going out (like the sound of a TV that is on, with no volume in a quiet room). Also, if I try to turn it on too soon(before the 1-5 minute 'cool-down' time), it will take 1-2 seconds to turn on, flash for a heart-beat, and then go blank again. When it does this, it also has that barely audible high-pitched sound.
One last point, it is being used in an air conditioned room, so no overheating problems from the environment. I also have my cheap sub-woofer about 8" behind the monitor on the desk.
I have a Westinghouse that does the exact same thing, this is an external monitor for my laptop, will shut down from 10mins-3 hours as mentioned above, Still found no soloution.
I know this is for a VS, but it may help my problem aswell.
I same issue for me, VP171B
any idea of how to solve this ???
my VP171b does this as well, it sucks!
It will work for a random amount of time (as you say, it can be hours or minutes) and then gets brighter for a few seconds, then goes black and the LED on the front panel stays on.
After you turn the monitor off for a few minutes it's fine again for a random amount of time, usually not as long though.
