  • Stuck in Standby: A software or hardware glitch can trap the TV in low-power standby mode instead of a complete shutdown. This prevents all processes from terminating. 
  • Background Features Running: Certain scheduling features are still active, like programmed Power on/off times, and can take over and override the power button. Timers and sleep functions can also sneakily run behind the scenes.
  • Overheating Problem: Caked-on dust clogs air vents and causes internal components to overheat. An overwhelmed cooling fan working overtime may not allow a complete shutdown while working to reduce temperatures. 
  • Loose Cable/Port Connections: Prolonged use can make AC cables slide loose or develop intermittent connections at ports. An unstable power supply disrupts the shutdown signal, reaching all circuits.
  • Outdated Software: Old or corrupt firmware could be missing new shutdown routines. Not having the latest patches also allows minor software bugs to emerge over time.
