Having a similar problem. Monitor goes black at random intervals, any where from 1 second to 20 minutes. When monitor goes black, monitor power button stays green. ( I interpret this to mean the monitor is recieving a signal) Shuting down the monitor for 30 seconds and then turning it back restores the screen, but only for a limited time. Monitor is six years old and is left on almost continuosly. (19" LCD - Dell)
When the monitor goes into herbernation/sleep mode the screen still emits light(glows black), but what I'm trying to describe is black, like no power black.
I've read elsewhere that the monitor may be overheating, it may have a moisture/humidity problem, video driver may be corrupted, or, like me, just plain old. My question is, is there any malware out there that might be the cause?
I will attempt to use the monitor on another computer to see if the problem re-occurs.
