Which DTV trouble call could be avoided with better customer education?

The scenario where the digital set-top box (STB) overheats could be significantly reduced through better customer education. Educating customers about the importance of proper ventilation and placement of their STB can prevent overheating issues. Customers should be informed that the STB should be placed in a well-ventilated area, away from other electronics that generate heat, and not enclosed in cabinets without airflow. Providing guidance on how to periodically check for dust accumulation in vents and the significance of maintaining a clean electronic environment can further aid in preventing this issue.

This approach embraces the proactive aspect of customer education, helping users to recognize the factors that contribute to overheating and take preventative measures, thereby reducing the occurrence of trouble calls related to this issue.
