Won't Turn On
Vizio Smart TV
Severity: CriticalWhat Does This Error Mean?
Unplug the Vizio TV from the wall for 60 seconds, then plug back in — this clears a standby lockup that prevents the TV from powering on. If the power light blinks but the screen stays black, press and hold the power button on the TV itself for 10 seconds. A completely dead TV with no light at all usually means a failed power supply board.

How to Fix It
-
Unplug from the wall for 60 seconds
Pull the power cable directly from the wall outlet — do not just use the remote. Leave it for a full 60 seconds to discharge the capacitors. This clears a standby lockup.
-
Press the power button on the TV
Vizio TVs have a physical power button on the back or side of the panel. Press and hold it for 10 seconds. If the TV turns on, the remote or IR sensor is the problem — try replacing the remote batteries.
-
Check the power outlet
Plug a lamp or phone charger into the same outlet to confirm it has power. Also try plugging the Vizio TV directly into a wall outlet rather than a power strip or surge protector.
-
Check the standby light
A solid white or amber standby light means the TV has power but is in standby. A blinking light is a fault code. No light at all indicates a power supply failure.
-
Perform a soft power cycle
With the TV plugged in and in standby (light on), hold the power button on the TV body for 10 seconds. This forces a hard restart from standby — different from a remote power cycle.
When to Call a Professional
If the TV shows no power light after a power cycle and the outlet is working, the power supply board has failed. Contact Vizio support for a warranty claim or a repair referral.
Frequently Asked Questions
Vizio TV white light is on but screen is black — how to fix?
The TV is in standby but the panel is not activating. Hold the power button on the TV body for 10 seconds to force a restart. If the screen stays black, the backlight may have failed — shine a flashlight at the screen in a dark room to check.
Vizio TV won't turn on after a power outage — how to fix?
A power surge can trip the TV's internal protection circuit. Unplug for 5 minutes, then try a different outlet. If it still won't start, the power board may have been damaged by the surge.
Vizio TV remote won't turn on the TV but the button on the TV works — why?
The TV's IR sensor may be obstructed, or the remote batteries are weak. Replace the remote batteries first. Also remove anything placed directly in front of the TV's sensor area.
