Stuck on Channel searching!!!

Some button got pressed and now theres a screen that says "first please connect cable system or an antenna to the terminal on the back then press the menu key." No command button other than MENU works: when i press the menu button it says "please wait tv is searching for your channels" and it runs through every channel. the problem is we have no cable-none at all. The tv is used only for playing DVD's. when its run through every channel words in red show up " no signal from antenna check connections then press the menu key" and then the cycle starts all over again. if i turn the tv off....even unplug it-when i turn it on again its at the first screen. "first please connect cable system or an antenna to the terminal on the back then press the menu key." HELP!!!!!!!!!!!

The problem is we have no cable-none at all. The tv is used only for playing DVD's. solution check dvd to tv wire or socket if it is ok then play dvd in another tv if it works fine then problem in tv. for that check tv tuner & its circuit for loose. check tuner itself

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

There are three ways you can connect a DVD player to a TV. Component video gives the best picture quality, but requires 3 cables for the video signal alone. S-video needs only 1 cable but it isn’t as good as component video. Composite video is the easiest connection to make, but gives the lowest picture quality.

No signal stuck on channel 2 with black screen. Model KDL37M3000


Are you connected to a cable or sat box, Are you connected thru antenna input on tv or a/v input. If connect to box thru antenna jack of tv do channel search to pick up ch 3 if box is set to that. If connected to outside antenna still do channel searsh but be sure tv is set to antenna. If connected via av or hdmi the cable or sat box is bad.

I dont have cable.i was using this tv just to play dvds and i accidentally hit channel search. now i get a blue screen that says" plerase connect cable system or an antenna to the terminal on the back...


Hi:
Using remote locate a button called tv/video or Input, turn on the DVD player and hit this button until you see your DVD player Logo. Most dvd players use either video 1 or 2, or componet or HDMI outputs. Seems you have changed the TV's input back to TV mode and you need to change it to a video mode input.

"Failed to receive broadcast"


On your TV remote,press "INPUT".It is hard to find,but it should be there.Select"TV" and press"ENTER" button.I believe it is on the top of the list.On some cable boxes you have to select channel 3 and use the cable box remote to change channels.Also,make sure your TV antenna setting is set to "Cable" from the "Air/Cable"(Antenna setting).You will have to read your manual to find out how to get to this menu.After that do a "Ch Search"[Channel search].This automatically searches for all available channels and stores them. It will take some time.You will see the channel numbers as it does it's search.This is done so when you press channel up and down keys it will only go to next channel available and not to one with no signal.Hope this is of some help.

How do I escape from an input screen back to watching satellite tv? Screen reads first please connect all signals and antennas to jacks and terminals on the back of the tv then press the channel up key...


Looks like your set is not receiving the signal from the sat. receiver. Make sure that the audio/video cable is in good shape and connected correctly, then select the correct input on your tv. If that doesn`t work try to connect a dvd or vcr on the same cable, if that is still no go then you may have a bad audio/video cable or there is a problem with your tv set. If it does work(dvd/vcr) then you`ll have to check your satellite receiver. Hope this help. Good luck
