I just bought an RCA TV and was ready to throw it out the window. Spent 2 days trying to set it up asking RCA 5 times for help and went online and still couldn't solve my problem.

If you are connecting your TV to a cable box, your channels are already there so you do not have to scan for channels.

How to program channels


go into settings and then rescan for channels

A channel scan is a vital part of utilizing your cable TV service. When a coaxial cable is connected to a TV, sometimes it will not display any channels until you configure the TV for your specific cable connection and scan for available channels. A channel scan can be applied to basically any type of TV or TV/VCR combo, even if you are missing its remote control.

Instructions
    • 1 Bring up the TV's menu. Look for a button on the front panel of your TV/VCR labeled "menu" or "setup." Press it and you should see a menu appear on the screen. Part of the menu should inform you what buttons you can use to navigate through the menu. If not, try using the volume buttons or channel buttons on the front of the TV and see if pressing those allows you to navigate through the menu.
    • 2 Specify channel scan settings. Once you are able to navigate through the TV's menu, look for the "channel scan" "auto-program," or "auto-tune" option. This may be inside one of the TV's sub-menus such as "setup," "channel setup," or the like. The key of this step is to specify your cable settings before running your channel scan. The "tuner mode" option needs to be set to "cable" rather than "air" or "antenna." You may have to specify what cable type to use, this will be set to "std" or "standard" for the vast majority of cable providers. If you are not certain what cable type you use at home, contact the technical support department of your cable provider.
    • 3 Run a channel scan. Once the scan settings have been set properly, run the scan (usually done by pressing a "start," "scan" or "begin" button.) When the scan is complete, check to see if you are getting all of your channels. Contact your cable provider if you are not sure how many channels you are supposed to be getting.

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.

A newly designed LCD TV has various capacity functionalities. For example, AV 2 or AV4 are connection capabilities with DVD or VCR recorder device peripherals. Once any devices are connected to the TV, an auto scan is required to acquire adjustment of what is common expection whenever powered on. USing the TV remote control, perform settings fucntionalities to acquire the auto scan to acquire connection functionalities. For example, refer to the TV user guide or manual on setting the TV channels. For TVs that are connected to subscriber providers cable tv or dishnetworks, contacting technical experts would readjust the TV signal receptables to display media. good luck

New tv connected to cable, suppose to have 52


Hello,
With the cable securely connected to your new TV, go into the Menu setup features and tell the set to AutoProgram all cable channels. It will then search for every signal. This will take a few minutes but give it some time to scan,
If it cannot find anything then you do not have a proper cable or antenna signal.
Cheers

Tv won't scan channels when connected to cable tv


Hello
The first thing is to try going in the tv's menu
It should be similar to this:
Menu>setup>channel setup

once you find something similar, run the channel setup and it should add in the channels

If that doesn't work, screw on the cable wire, unplug the tv for a good few minutes, then replug the tv and it should automatically scan



Hope this helps

Dynex (no database) since power outage


What you have to do it go to the TV Menu and go to channel. Then go to channel scan and do one of those. THe problem is that is just doesnt know where to look for channels, but a quick scan will fix that.

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!
