My Vizio TV Turns On then Off!

My Vizio TV turns on then off!

Don’t push the power button like an elevator button, turning it off before it has a chance to come on.

This isn’t something as obvious as a remote control war.

I’m assuming you aren’t hearing weird static as the power supply flickers out.

I would probably hear a pop if it went out.

It may pop with a major failure or you get intermittent failures as capacitors and the power supply start to burn out.

Something like that requires parts getting replaced.

Most likely the power board if not the power board. I’m assuming it isn’t a more obvious hardware issue like a frayed cord.

A cord shorting would be a fire hazard.

Make sure your TV isn’t turning off as a power saving measure.

I don’t use that function.

The issue could be a software glitch with the TV’s last update.

My gaming console updates, but TVs don’t.

If the TV is an HD TV with an advanced controller, yes, it could have a software glitch from its last update.

I have no idea how to fix that.

Power cycle the TV just like the gaming console.

That means unplug it, wait a couple minutes, plug it back in and turn it on and hope it stays on.

You could also try turning it on using the button on the TV and seeing if it stays on. If it does, the problem is probably the remote control.

It is more likely the TV wouldn’t turn on because the remote control is dead than have it cycle on and off.

I can’t rule out that there is an unwanted signal from a stuck button or malfunctioning IR sensor.

So hide the remote and see if the TV stays on.

I’m also assuming the TV isn’t connected to a surge protector with a malfunctioning battery.

No, it isn’t, but if it was, I’d know to make sure the backup battery or surge protector was on and wasn’t shorted out.

With a Vizio TV, you still have to rule out it isn’t a hardware or software issue. Hit the menu button on the TV or the remote to see if the menu comes up.

What if it does?

Then you know the issue isn’t the display but the settings. A screen that alternates between satellite or cable and black is then an issue with the signal or power at the set top box.

I’d expect the cable box to flicker if that was the cause.

The TV could be flickering because the power cable is the issue. Unplug it and make sure you plug it in securely.

I haven’t unplugged it to power cycle it yet.

I can’t say this isn’t a glitch with the wall outlet.

If that was the case, the DVR and rest of the stuff plugged in the same outlet would be turning off and on.

Big screen TVs are power hogs, and it may be dimming and thus dying when you turn on other stuff because the wall outlet can’t provide enough juice for all the energy hungry devices.

This does become a great excuse to unplug the kids' gaming devices.
