Viewsonic Flat Panel Monitor Trouble

I have three viewsonic monitors hooked up to one computer. the other
day i turned them off to do some computer maint and then when i
turned them back on the screen and the green power light just flash.
All of them did it at first, but then one of them came back on. What
would make them do this and is there some part that I could buy and
put in myself to fix this? Any info would be very helpful. Thanks in
advance.

If they were working before, I'd say your video card can't figure out
what one to use.

Try unplugging all but one monitor.
