IU have encountered a very puzzling problem.
The symptom is that suddenly the monitor goes black, the pc sound is still on. This happens in a seemingly random way, it might be minutes between events or hours.
I have found if I unplug the monitor cable from the pc the monitor puts up its usual searching for signal message.
If I then immediately plug the monitor back in the pc, the monitor has normal display.
I have tried inspection of the cable and wiggling the connection without any result.
I am currently thinking this way. Since when the failure occurs the monitor goes black, without the signal missing message, that it is the monitor that is faulty. If this is true then why does it come on again immediately when plugged in again.
Any ideas welcome. But I do not have access to another monitor
