Vizio TV Input Troubleshooting for No Signal and Missing Inputs

Choose the check that matches your screen

When your TV responds but your player's picture won't appear, we'd check the powered source and selected port first, because both are part of getting that device onto the screen. If the remote won't change anything, we'd work on its response first so you can actually choose the source you want.

The worked examples below apply to the 2022 US VIZIO V-Series and D-Series families. Pick the behavior you can observe now: a selected input showing No Signal, a button that doesn't respond, a source absent from the list, or missing channels from a direct antenna or cable feed.

You can select an input, but it says No Signal

Start with the name beside the connection already in use. That label tells you which input to choose, while checking the connected device's power addresses the source end of the same path.

For both families, the V-Series source-selection checks (opens in a new tab) and D-Series source-selection checks (opens in a new tab) use the port label, the device's power and the TV remote's INPUT button. Work through them with the device you actually want to watch.

1. Look behind the TV at the port your device is connected to. Read the name next to that port so you have the connection's exact label.
2. Check the connected device and turn it on if needed. Confirm that the source itself is powered on, as well as the TV.
3. Press INPUT on the TV remote and choose the port you identified. Check that your selection matches the connection carrying your source.

Now look for your source's picture. If you couldn't complete the selection, use the branch that explains why: remote response when the button does nothing, or input visibility when the source isn't offered.

For a V-Series or D-Series that's on but shows no image, you can also select a different input with INPUT. Keep track of which source you're viewing so a picture from another device doesn't get confused with the original source returning.

INPUT doesn't respond on the remote

Aim directly at the TV's remote sensor and press only one button at a time. Remove any object blocking that sensor, then try INPUT and watch whether the TV responds.

These D-Series remote checks (opens in a new tab) also apply to the V-Series example. The target is the sensor itself, so keep your attention there when checking your aim and anything sitting in front of the TV.

If the buttons still don't respond, replace the remote batteries using the procedure below. You can also use the TV's own input control or the mobile app to make a selection without the handheld remote.

Replace the remote batteries correctly

For the remotes covered by these V-Series and D-Series manuals, VIZIO recommends two new Duracell AAA alkaline batteries. Use the correct battery type and pay attention to the compartment's polarity markings when fitting them.

The V-Series battery replacement procedure (opens in a new tab) and the D-Series procedure use the same cover movement and two-battery arrangement. Finish by closing the cover before returning to the remote controls.

1. Push and slide the cover down, then lift it away. The battery compartment should now be accessible.
2. Replace the old batteries with two new ones. Match each battery's + and - symbols to the corresponding symbols inside the compartment.
3. Replace the cover and slide it closed. Try the remote again and watch for the TV's response.

Dispose of the removed batteries according to the laws and regulations where you live. Many places prohibit putting batteries in household waste, so use the disposal route permitted locally.

Use the input control on the TV

With the TV already on, an ordinary press of its Power/Input button changes to the next input source. Use individual presses and watch the selection advance until you reach the source you want.

VIZIO gives two location descriptions in both manuals: its troubleshooting advice describes an INPUT button on the back, while its control description places the combined Power/Input button under the sensor. Check your set against the V-Series control descriptions (opens in a new tab) or D-Series control descriptions (opens in a new tab) when locating it.

The result to look for is the input changing after a press. Once the desired source is selected, check its picture separately from whether the remote has started responding.

Select a source from your phone or tablet

Your phone or tablet offers another way to select a source through the app described for your TV family. The V-Series instructions name VIZIO SmartCast Mobile, while the D-Series instructions name VIZIO Mobile App.

For the V-Series example, make sure VIZIO SmartCast Mobile is installed, then open it. Tap the Device list, select your TV, tap the Input key and choose the input you want, following the V-Series app input controls (opens in a new tab).

For the D-Series example, open the installed VIZIO Mobile App on your phone or tablet. Tap the Device list, select your TV, then tap INPUT and choose your source using the D-Series app input controls (opens in a new tab).

An input has disappeared from the list

A hidden input disappears from the input list, so visibility is the setting to check when the list opens but your source isn't there. This check restores the choice to the list; selecting that source comes afterward.

On the 2022 US D-Series, open Menu > System > Hide from Input List. Highlight the missing input's name, then use Left/Right to switch it from hidden to visible with the D-Series visibility controls (opens in a new tab).

For the V-Series, the input visibility control (opens in a new tab) also uses Left/Right to toggle a highlighted input between visible and hidden. Not every input can be hidden in either family, so use this check for inputs that offer the visibility toggle.

Return to the input list and look for the source's name. When it appears again, you can choose it and continue with the source-selection check if its picture still isn't showing.

Direct antenna or cable channels are missing

Use this branch for an existing antenna connection or cable coming directly from the wall to the TV without a cable box. A scan lets the TV discover channels before displaying their programs and associated information.

The connection determines the check. A cable or satellite receiver already feeding the TV through HDMI belongs with the connected-source checks above; the direct antenna or cable feed uses the TV's channel scan.

On the 2022 US V-Series and D-Series, open Menu > TV Channels > Find Channels to begin the automatic scan. This is the shared path in the V-Series channel controls (opens in a new tab) and D-Series channel controls (opens in a new tab).

Wait until the scan reaches 100%, then highlight Done and press OK. Check the available channels after completing that sequence, including when some channels were present before you started.

If you cancel the scan, channels already discovered are retained. Seeing some saved channels after cancellation therefore means the TV kept those discoveries, even though the search didn't finish.

If you've moved your D-Series TV to an area with different channels, run the scan again so it can find the channels available in that area.
