Here we will introduce a step-by-step tutorial and will not only resolve the issue but most likely reveal the true cause.

This will help you prevent the issue from appearing in the future and scan for channels uninterrupted.

Let’s start with the inspection first:

Step #1 Setup Inspection

First of all, you need to make sure that both your Vizio TV and tuner are plugged into the power and working. The most secure way of doing so would be to remove power dividers and plug both devices in separate (standalone) wall outlets.

Next, you should inspect the setup for any loose cords. Cables usually come loose for a variety of reasons over time, and it is good to make sure that both ends are plugged all the way in.

Moreover, it is recommended to unplug everything and reconnect from scratch to exclude the possibility of a faulty connection.

Lastly, take a last look if there is a cable that is severely twisted or under pressure. If you locate anything like that, simply straighten the cable and proceed with the next step.

Step #2 Choose the Correct Source

There is a misconception regarding the faulty part whenever something does not work. In case you’ve selected the wrong input source, your tuner will appear not to work, so let’s take a look.

Note: Each of your TV inputs should have a label right above the port (HDMI1, HDMI2, RCA, etc..)

  1. Take a look at the inputs of your TV to find where your tuner is connected.
  2. Memorize the label above the port.
  3. Take your Vizio remote and press the Input key.
  4. From the Input menu, select the port your tuner is connected to.
  5. Confirm the port selection by pressing OK.

If you cannot see the input your tuner is connected to, for instance, HDMI1 it might be renamed. Newer Vizio TVs automatically rename the input, according to the device connected to them.

For example, if you connect a computer to HDMI1, in the TV sources menu, it will appear as a Personal Computer, instead of HDMI1. If you connect a gaming console, for instance, it will appear as Playstation4 or Xbox.
