Typical triggers

A Vizio TV turning on by itself is often caused by HDMI-CEC (Consumer Electronics Control) signals from connected devices, a stuck remote button, a scheduled timer, or a power glitch. HDMI-CEC lets a game console, streaming stick or cable box power on the TV when it wakes up.

• Vizio calls its CEC feature “CEC” in the System menu.
• Low batteries or a remote with a stuck power key can send signals.
• Firmware bugs and voice assistants such as Alexa or Google Assistant can also trigger power-on.

Fixes

Disable CEC in the TV menu, unplug HDMI devices one by one to find the culprit, replace remote batteries, and check scheduled timers and Quick Start settings. Update firmware via Menu, System, Check for Updates. Power cycle the TV by unplugging it for 60 seconds. If the problem continues, contact Vizio support or use the warranty, which is usually one year in the US.

Typical triggers

A TV that turns on by itself may be responding to HDMI CEC commands from connected devices, a stuck remote button, a sleep or wake timer, Chromecast or voice assistant activity, or a firmware bug.

Fixes

Turn off CEC or Device Control in settings, remove batteries from the remote, disable timers and update firmware. A factory reset can help.

Smart TV control systems

HDMI-CEC lets devices control each other, and it appears as SimpLink, Anynet+ or Bravia Sync under different brands. On Vizio it is called CEC. A connected gaming console or streaming box can wake the TV. Scheduled updates and voice assistants (Alexa, Google) can also power it on. Remote buttons that stick can send repeated commands.

Fixing it

Open Menu, System, CEC and turn off, then test. Remove batteries from the remote and clean it. Disable Quick Start or Power Mode set to Eco. Update firmware under System, Check for Updates. A power cycle by unplugging for 60 seconds helps. If it continues after a factory reset, contact Vizio support.
