VIZIO's articles give the update path: press the Menu or Gear button, go to System or Admin and Privacy, choose Check for Updates and follow the prompts, and note the TV may restart after installing. The TV must be online, so check Menu, Network, Test Connection first; VIZIO's Wi-Fi article covers restarting the modem and router for ten seconds, power cycling the TV for five seconds and improving the signal. VIZIO publishes firmware information pages per model, listing versions and changes, useful to compare with the version shown under Admin and Privacy, TV Information, Firmware;
The checks in more detail
the Bluetooth headphones article, for example, depends on firmware 1.510.21.1-1 or newer. An outdated version can break AirPlay, apps and remote features, which VIZIO's AirPlay article says directly. If an update stalls, leave the TV on for several minutes, then power cycle it. Do not unplug during installation. Some settings may reset after an update, so note your picture settings. If updates never appear, the model may be at the end of its support, and a factory reset under Admin and Privacy, Reset to Factory Settings is a last resort that erases settings and logins.
If the TV cannot find an update after a good connection and a power cycle, contact VIZIO Support with the model, serial number and firmware version. Firmware pages list versions per model, so compare the number on your TV with the newest listed before deciding an update failed. Run the update when the TV will not be needed for an hour, on a wall outlet, so no interruption leaves it half installed.
Some updates install in two stages, with the TV restarting once in the middle, so do not assume the process has failed if the screen goes black for a minute and then returns. If the update was pushed by the TV automatically overnight, check the version before assuming nothing changed, since the TV may already be on the newest release. Take a photo of the firmware screen before you begin, so that after the update you can show clearly whether the version number changed.
