The display on my ASUS notebook goes black for 1-2 sec when the power supply is plugged in or unplugged. 

 

When I connect the power supply, it goes black for 1-2 sec, then for an additional half second of so, it's dimmer than usual. 

What could be causing this?

When you say the display does this, do you mean this is normally what the display does and you just wonder why, or are you describing something unusual that it has now started to do?

A repair shop replaced my lcd display and the video cable.  When I got my notebook back, it was going dark like this when power is connected / disconnected.

If it's not the normal behavior, and it's the result of a repair, it should go back to the repairer.
