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.

Digital channels are not working

If your TV is connected to a "cable" box, e.g. you're using cable TV ... then it is the cable TV box that determines what you can get (based on your cable subscription). Yes, I know that some cable TV and satellite TV service providers will only deliver HD digital channels when you pay an additional (monthly) fee for HD digital channels.
If you plug the cable directly into your TV (i.e. not use the cable box), you may be able to do a channel scan on your TV, to pick up the digital channels ... but you will loose the convenience of using the features that your cable box provides .

MMy Vizio 32" tv only gets 16 channels

If your Vizio TV has a built-in HD converter, 16 channels is what you can expect. If the channels are identified with decimals such as 10.1, 10.2, etc. they are HD. The cable connection you refer to must be connected to an antenna, otherwise you would have a cable box and a monthly bill from some cable company

I can only able to see 65 channels in my new samsung t.v[LCD]but in my calbe there are more tahn 70 can i see the all channels

When you scan for channels, make sure you choose "cable" for the setting under the "Antenna" tab.

channel --> antenna --> choose cable

This should let your TV show more channels. Most cable companies issue cable boxes now a days, which you plug into your TV. You usually change the channel by using the remote for the cable box.

Hope this helps

In just bought new Toshiba regza 40" Lcd tv and auto tuned it, but the picture is terible , snowy and colours are not good, what to do...

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


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.

I have a JVC tv model AV 27495. I hooked it to the cable with the cable cord. I can only get cable 2 channel. I can't access any channels. What do I need to hook into the cable? Do I need a box since...

Yes, with the Direct TV box it did all the tuning and your TV had only to be on one channel, normally ch 3 or ch 4. Now that it is not there any more your TV tuner must do the work. You now will have to tell the TV to search for channels. Use your remote and TV menu to do this. You will be able when the search is complete to see some of the cable channels but other premium cable channels you won't be able to see without a cable box.

No signal onthe screen

If you are connected to a high definition cable box or satellite tv box you would not need to turn to channel 3 on your television. The television would need to be in the right input either component or hdmi. If someone connected the tv to the cable box or satellite tv box with a coax cable like an antenna cable then the tv channels will be available on channel 3 as well but they will not display in high definition. You change channels with the cable box/satellite tv box remote control. If the above is not correct and you are only connected to an antenna cable and not to a cable box or satellite tv box you will need to complete a channel search from the tv menu. It sounds like you are using a cable box/satellite tv box and that the tv is on the wrong input. If the cable box/satellite tv box is not working (i.e. just a black screen) on your television than that is a different matter entirely.

Describe how to program channels on lg tv

Very simple -
You will need to find a feature that says 'Auto Tune'

This first will ask you to select between:
1) Regular TV - off air antenna - connection
2) Cable TV - connection
3) DSS TV - Connection

If you aren't ready for digital TV with your antenna or cable you may get very few channels.

TV will not turn on to channel 4 everytime. I have a cable box and need the tv to remain on channel 4.

As long as the tv is not unplugged it should stay on the same channel when turned back on. If you have the tv plugged into the cable box, when the box is shut off it basically unplugs your tv and the tvs memory is reset. The tv should be plugged in to its own outlet or leave the cable box on and turn off the tv. If you turn everything on, cable box and tv, and have a picture, go into the tv menu and auto program the channels, it should only lock in on channel 4 since it will be the only channel the tv will receive.
