Are you receiving the other cable channels? If so, then perhaps it's the RF cable connected to the TV. Sometimes they act more like an antenna than a direct connection.

Televison station won't scan


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.

How do I get a signal


You need to plug an RF cable into the RF Input. Connect that to a TV antenna, cable, or satellite receiver. You will need to run a channel scan to allow your TV to know what channels are available.

Display says please run auto channel scan


It sounds like it is not seeing any signal. Do you have the input set for the proper type? Air or Cable

Check your RF connection to ensure you have a signal coming into your television.

Have a curtis tv , trying to run autoscan, it runs, but it doesn't locate any channels. I have a comcast converter box also. Not sure why autoscan isn't working. Or do I have to set up my comcast...


For the auto scan to detect there must be channels present on the CABLE that is connected to the RF input- TUNER INPUT- of the TV.
So check with your cable operator for the channels and you can connect. however if you are using a digital box then the channels are memorised on the box as only the output of the box is connect to the video/audiop inputs of the TV. if so select line in/video 1/2.

Connect the RF (cable wire) to the CABLE RF jack on the back of the TV. It sounds like you have it connected to the AIR RF jack. Next, press the ANT button on the remote. Not go into the TV SETUP menu and do the auto program again. This should fix your problem, best wishes.

How come I can play video tapes on my sony video casette recorder, but can not record tv channels on my recorder?


i guess you havent connected it correctly.

Run your ariel int antenna (RF) in on the video recorder.

You will need another (RF) cable that connects from RF-out on the video recorder to antenna in on the tv.

put the tv onto channel AV (or video)

tune (scan) the TV channels on your video recorder.

NOW you will be able to record the channel you see it play on TV


hope this helps!

I just got cable and I cant get the channels to come in as cable channels. I lost my manual and have a universal remote?


Hi gail dahl,
I am happy to help.
From the Video Menu the Tuning Band must be set to Cable and not to AIR or Antenna. You will nee to run Auto Scan for channels from the Menu also.
I have provided a link to download the manual. http://esupport.sony.com/US/perl/model-documents.pl?mdl=KDL40XBR2&LOC=3

Not able to scan stations


I don't understand why you would bother to scan channel when you have directv or dishnetwork???
directv or Dishnetwork required their units in order to watch any channel,which means:
A. Depending on your TV setting,if you use RF connection from your basic directv to the tv,you would have to leave the TV on Ch.3 or Ch.4.to view the rest of the channels,you have to change it from the directv or dishnetwork box. You are NOT able to scan the rest of the channels from the TV,bottom line!!
If you have comcast or your local cable provider,once you have activated,you could use the RF signal coming out from the wall plate straight to the tv and go to TV auto programming,it will auto scan the available channels for you.
Don't waste your time on directv.
If you are thinking about recording from your BASIC directv or dishnetwork box, you would connect SAT. signal from the wall plate to the directv box,then use composite video/audio output and connect straight to your VCR/DVD player under composite video/audio input. Now you could record the viewing channel to the VHS.
Good luck!
