Scanning dtv channels

When I select dtv input and try to go to the TV icon on the main menu the screen turns blue and will not let me exit or do anything. I have to turn the TV off and then I can return to the TV input and watch DirecTv. Can get to the TV icon from this input. Have some digital channels that I was able to pick up off antennae but now I cannot scan for them. Any help would be appreciated.

    Periodically when I turn on the TV to the DTV input, or switch to that input from another one, the screen remains blue and the OTA signal never displays. I can change the volume but not the channel and the other inputs work fine. My "solution" so far has been to turn off the tv and wait for a bit then try again. I have left the set unplugged for two hours but that failed to improve the situation. My googling leads me to believe there is a problem with the ADC, but the same googling indicates that I shouldn't mess with the ADC settings in the service menu. Any thoughts? Thanks.

    I have the same problem. NTSC works fine, but when I switch to DTV, I get a blue screen. Usually when you have a weak signal or no signal, it will go to black screen and display no signal. Mine doesn't do that, it stays at the blue screen. This happens most of the time now. When I go to the scan mode on the menu, the menu disappears and does not return. Then the TV is hard to turn off and back on.

Go to menu setup and do the full system reset setup option... Then before you scan for channels make sure it is set to cable... This fixed the problem for me.

What's your question? I just bought Finesse tv but it does show any channels its just blue screen only ive tried to do automatic channel preset but nothing happens


The blue screen shows that you do not have a signal coming into the TV. So it sounds like you have the wrong input selected and or no aerial connected. Check the manual look for the inputs menu any cycle through them. My best guess is the DTV (Digital TV) input is not selected or you have it selected but no aerial plugged into receive a signal.

Once you have confirmed this run the automatic channel pre-set again.

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.

TCL Blue Screen "No Media"


I have this tv, just had this exact problem and just fixed it. All this screen means is that you have pushed the "media" button on your remote and it's telling you that nothing is plugged in to your usb drive on the tv. If you plug in a usb key with pictures or video on it, you'll be able to view those from this screen. Otherwise, to exit this elusive "no media" screen, grab your remote and hit the button that says "tv" to get back to the blue screen that says "no signal" and from there, you should be able to hit the "input" button on the remote and switch between your inputs of choice. My favorite input is my apple tv plugged into hdmi 2. yay!

Have a vizio lcd tv . can not get any channels today with the switch over to digital. i use an antenna


Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.
