Hello Cynthia,

Wlelcome to Experthelp.com. have you tried pressing the power button for 30 seconds instead of 15? If you are receiving a "No Signal" error message, first 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.

Once everything has been verified, please follow the steps below depending on which type of connection are you using on the TV.

Vizio TV -

No Signal" 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.

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.

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.

The following videos show troubleshooting steps to use when a "No Signal" or "No Channels in Master List" messages appear.
 


 

NOTE: 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. You can follow the steps below instead.

Vizio TV - "No Signal" on AV (Composite), Component or HDMI ports

 

  1. Power off all HDMI devices connected to the TV.
  2. Disconnect all HDMI cables from the TV.
  3. Power off and unplug the TV’s power cord from the surge protector or wall outlet.
  4. Press and hold the TV power button for 30 seconds.
  5. Reconnect the HDMI cables back into the HDMI ports on the TV.
  6. Re-plug the TV’s power cord back into the surge protector or wall outlet.
  7. Press the INPUT button on your remote until the correct input mode is selected.

All ports should now work again. Please let me know if you are already satisfied with the answer or have additional questions by replying to this message. I will be waiting for your response. Thanks.

Well, before I contacted you - I had done ALL that you presented.  And as a last resort when you sent it again, I wanted to be able to tell you I had done it all AGAIN and it did not work, but guess what - of course, - it now works.  Go figure.

Thanks for letting me know. Did find out what was the cause of the no signal message?

I am thinking it was an input problem that was causing the no signal issue. Also keep in mind that you need to press the power for 30 seconds instead of 15. But I am glad this is now working. Please let me know if you are already satisfied with the answer or have additional questions by replying to this message. I will be waiting for your response.
