VIZIO's black screen guide starts by checking that the TV has power: find the power light, usually on the front, bottom edge or lower left, noting that some models show none. Power cycle the TV by unplugging it, holding the physical Power button three to five seconds and plugging it back in. Then try the mute trick: some apps can leave the display screen-muted while audio plays, so hold the Mute button on the remote for about five seconds.
The checks in more detail
Press the Menu or Gear button to see whether the TV menu appears. If it does, the display works and the fault is the input, cable or connected device, so press Input, pick HDMI 1, 2 or 3, reseat the HDMI cable at both ends, try another port and cable, restart the device and test the device on another TV. If there is no VIZIO logo, no menu and no visible light from the screen, the TV may have a display or backlight issue.
VIZIO says service may be needed only if the TV is on, you can hear sound or see it respond to the remote, the logo and menu do not appear, the screen stays black after a power cycle and the problem shows on all inputs with all devices. The article stresses that if the menu appears, the TV display is functioning, so check the device, cable and input before requesting service.
The Mute button trick costs five seconds and applies only to a screen that was muted by an app, so try it before assuming anything is broken. Photograph the screen with your phone camera; some cameras reveal a faint menu the eye misses, which helps tell a backlight fault from a signal fault. Compare a cold start with the TV after an hour of use; a backlight that returns when cold points at a failing strip rather than a dead one, and that detail helps a repair shop quote correctly.

- Whether the power light is on
- Whether the Menu appears on the screen when you press the Menu button
