Did you check the monitor cable connections at both ends, computer and monitor, for loosening ?

Did you check the input selection of the monitor ? Some monitors have more than one input (DVI, HDMI, VGA, etc.) and selection of the input is not automatic, depending on input. It is not uncommon that the input is haphazardly switched to an unused port while cleaning the monitor.
