go to the Menu and you should find it.

The tuner on your TV is not tuned to the output channel of your cable or satellite box. Usually this is channel 3 or 4.

If you are receiving a "No Signal" error message, verify that:

1. All of the cables physically connected to the TV and the input device are secure.
2. The input device is turned on.

Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:

1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
2. If the TV input is not selected, press INPUT until the TV input mode is selected.
3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
4. Highlight Tuner Mode and select the correct option:
   • Antenna-over-the air signals from an antenna
   • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
5. Select Auto Search or Auto Channel Scan. (This varies by model.)
6. When the search reaches 100% complete, exit to the menu.
7. Check the available channels:
   • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
   • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.

If this does not resolve the issue, power cycle the TV and then re-run the channel scan:

1. Turn off the TV.
2. Unplug the TV from the electrical outlet.
3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
4. Release the power button.
5. Plug the TV back into the electrical outlet.
6. Turn on the TV.

Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.

1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

This video shows troubleshooting steps to use when a "No signal" message appears.

What is your TV signal source? Press the Input button on the remote and try another input. (Make sure a DVD player or set-top box is on.) If you are on the TV input, try a different channel. Next make sure that your cables are securely connected to the TV and devices. Replace with new cables to test them. If you use an OTA antenna with a splitter, try a direct connection. (Similarly, if you have an amplifier on the signal, try a connection without the amplifier.)

For OTA or direct cable connections, try accessing the Channel Setup menu and rescanning for channels.

I hope this helps.

(I get some weak channels that give No Signal messages when the transmitter has a problem or the weather is bad. I've also had a signal splitter/amplifier fail and block specific channels by becoming a filter. The direct connection identified the amplifier problem.)

What type of antenna are you using? Or what is your source for accessing channels? (i.e. - are you connecting to a cable tv service box or are you using a receiver ect.) Make sure that your source is connected to the input method that you are currently using on the tv.

There are many input methods to choose from in the settings of the tv. They are generally called antenna 1, antenna 2, cable, aux, hdmi - and a few other names. There should be a button on your remote to change them. The function is usually called "source" or "input". Press that button to change the input method until you get a picture on the tv or pick up some sort of reception. when you have the tv set on the same method of input that your antenna source is connected to, you will get channel reception or some sort of picture. Thats when you use the menu functions to auto find channels for you and let it go through its checking scan to report how many it has picked up.

If its running the scan for channels and not locating any stations, and the picture is either scrambled with the white noise sound tv's make when off channel or if its just single color screen without any sound - then you know the antenna input method you have chosen on the back of the tv is not the current method set in the settings under the menu key.

Most of the time the inputs are labeled on the back. If you look under the cable antenna connection, it should say "cable" somewhere in small print - or "antenna 1 input", antenna 2 ect. Look on the back of the tv. If you are using RCA jacks that are labeled right and left for sound and a third connector for video ect, look for the name of the input method of those three connections on the back of the tv. It should be marked as input - aux 1 ect. Then just change the source chosen in the tv to match it and have it auto program your channels.

Hello
First of all reset the TV. for that

press and hold the POWER button
on the TV control panel for 5 or more seconds to reset the TV.
Then connect the TV tt any source like outdoor areiel or cable box etc, select the appropriate input, and retune the TV. First of all, connect it to an external antenna, and set it to autotune.

• You must configure the ANT/CABLE input source before

programming channels (-left-hand column).

• If the ANT/CABLE input signal type is set to Cable, the

automatic channel programming process erases channels

that were previously programmed into the TV's memory.

• If the ANT/CABLE input signal type is set to Antenna, the

automatic channel programming process adds newly found

channels to the existing set of programmed channels (and

does NOT erase channels that were previously

programmed into the TV's memory.) To remove an Antenna

source channel from the memory, you must manually delete

it.

• To tune the TV to a channel not programmed in the channel

memory, you must use the Channel Number buttons on the

remote control.

• Programming channels when the ANT/CABLE input is

configured for Cable will take substantially longer than when

the antenna input is configured for Antenna. This is normal;

however, once channel programming is finished, you should

not have to repeat the programming process again unless
your Cable TV service lineup changes significantly.
Find out the received channels are clear or not. If they are clear, your TV is perfect, and the input device you connects ot the TV is faulty. OK.

According to the user's manual on page 16, press Menu and open the Setup menu. Highlight Installation and press Enter. Open the Terrestrial menu and highlight Input Configuration. Select the ANT1 or ANT2 (whichever the antenna is connected to) and select input source Antenna [not cable]. Highlight Done and press enter. Now rescan your channels. If you still get nothing, try relocating your antenna to a better place. Digital TV is highly dependent on line of site signals. So if you are in a mountainous region or surrounded by a lot of high rise buildings, you may not receive a good enough signal to register channels on your TV.

Hello. I may be able to assist you. If you are using a direct cable connection from the wall outlet;

• Check the incoming cable or antenna signal connection to ensure that it is properly secured to the TV's antenna input.
• If the connection is good, perform the automatic installation again to search for all available channels.

If you are using a coaxial connection from the Cable or Satellite box to the TV;

• Set the TV to the channel specified by the service provider.
• Change the channels at the Cable or Satellite box to view the program.

If you are using a video connection (CVBS, S-Video, YPbPr, HDMI) from the source (DVD, Cable or Satellite box) to the TV;

• You do not need to perform automatic installation to search for the channels.
• Press the 'SOURCE' button on the remote control repeatedly to select the correct input source.

If you are using an HDMI connection from the source (DVD, Cable or Satellite box) to the TV;

1. Reset the TV and source by unplugging it from the power outlet for 30 seconds.
2. Turn on the TV and press the play button on your source device. If the source is HDMI CEC compliant, the TV will automatically switch to the HDMI input.
3. If your source is not HDMI CEC compliant, turn on the TV and switch to the HDMI input.
4. Turn on your source.

If you are sure you have selected the correct input or channel but still have no picture or sound;

• Try resetting the TV by unplugging it from the power outlet for 30 seconds.
• Press the 'SOURCE' button to select the correct input source.
• Check the connection cables.
• Try the connected source with another TV.
• Connect a different source on the same connection of your TV.

Can you confirm that you didn't have any input signal? My wife once accidentally pressed the reset button on the remote and the TV was stuck in this state. I tried to hook up an antenna to the digital antenna input and let the TV search for a channel. It did find a station and got out of the channel search mode, which was all I needed. Then, I unhook the antenna and continued to enjoy my DVD movie. I didn't check the manual. So, it's possible that there is a better solution. My TV was working fine and I think it just has a terrible user interface. I'm not sure about your TV's condition, though.
