Modern smart TVs enter standby mode rather than fully shutting down when powered off via remote. This design offers significant advantages including faster startup times, background software updates for operating systems like LG's Web OS, Google TV, Amazon's Fire TV OS, and Roku OS, and streaming app updates for Netflix and YouTube. Most critically, OLED TVs rely on standby mode for automatic compensation cycles (pixel-refresh) that prevent image retention and burn-in. Interrupting this process by unplugging the TV can cause uneven display wear over time.

ENERGY STAR-certified TVs in the United States must consume no more than one watt in standby, amounting to roughly 9 KWh annually or about $1.50 on power bills. However, electricity costs vary; California households pay roughly twice the national average. For extended absences, unplugging saves this minimal standby power.

Periodic reboots are recommended to clear background processes and improve responsiveness if lag occurs. Users should consult their manual for proper reboot procedures, as abruptly pulling the cord can interrupt maintenance tasks. Some TVs offer a reboot option by holding the remote's power button.
