Explanation

Since the monitor receives power but displays no image, the next logical troubleshooting step is to verify the video signal cable (VGA) is securely connected. A heater placed near a desk could physically displace or loosen a cable connection. With power confirmed, a loose or disconnected video cable is the most likely cause.
