My desktop monitor currently doesn't display anything. It's a pitch black screen despite the computer fully functioning in the background. Also, the power button for this machine is green, not yellow, which tells me that some data is being sent to the machine. When I disconnect the VGA cable, the power button usually turns yellow.
Trying to use my monitor as a secondary display for my laptop (which I'm on right now) yields the same problem.
But here's where it gets really weird: If I press the power button to turn the monitor off for a brief moment, and then turn it back on, I will get a display on the screen for about 1.5 seconds ... only for it to suddenly go dark again.
In the brief moments I can get the monitor to work, I can see my Windows desktop image in the background, with all my icons. So that at least assures me that the computer itself is still booting up.
I also use a VGA-to-HDMI adapter. But I'm fairly certain that isn't the problem because, as mentioned before, switching to my laptop still causes the same problem of the monitor only briefly working before going black again. I can connect my VGA cable into my laptop directly, so eliminating the HDMI connector has no effect. Thus, the connector isn't the problem either.
So at this point, we've narrowed the problem down to one of two components: The monitor itself, or the VGA cable?
Is there any way to tell definitively which one is the problem?
