Hi,
Did you performed auto tuning/ auto scan to store available channels in tv memory through tv menu?
There would be an option for tuning channels, select it and let tv scan available tv channels in cable.
Let me know if you have additional question.
Thanks.

SOURCE: Sharp digital tv cannot receive digital signal

This television would benefit from an hdtv indoor outdoor amplified antenna not obstructed by trees, aluminum, bricks, and etc. Make sure the signal type is air and not cable and complete a channel scan during primetime tv hours after connecting to this antenna. Buy a large one that you can mount to the wall usually in a large flat box on the shelf in the store. Philips has one sold at Walmart.

Do you have to have an optical cord from receiver to tv..koss model ks3102..if not i have rca cords were do cords go.


HD broadcasts by TV stations are often broadcast in Dolby Digital. If your TV can output Dolby Digital or HD then you will need to have the TV connected to the receiver via either the optical in, or the coaxial in. If the receiver can get the Dolby signals via the Coaxial and the TV can send them via a Coaxial socket it should work. Don't forget to set your HD set to output Dolby signals. If the TV or Receiver can only send Dolby via the optical you will have to use that. Optical cables can be picked up cheap these days. I have seen them in pound shops!

No sound using optical cable connected to LG smart tv 60LN5600


Your receiver has 2 optical inputs. If you plugged in the cable to Input 1, you can select the "CD-R" Input on the receiver. Then use the "Signal Select" button to select Optical 1 (O1).


You can also use the "Input Select" buttons on the remote until the receiver says "Digital". Then use the "Signal Select" button to select Analog (A), Coaxial 1 (C1), Optical 1 (O1), or Optical 2 (O2).

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 connect my cable box to my tv


Connect the coaxial "Cable In" cable to the "Cable In" port on the back of your TV cable receiver box. Make sure your receiver box is not plugged in yet. 2 Take the TV audio/visual cable, and connect the red, blue and green ends to the corresponding color "Cable Out" ports on the back of your cable receiver.3 Take the other ends and plug them in to the red, blue and green ports under "V1" on the back of your TV.4 Take the audio cord with the red and white ends, and connect them to the corresponding color ports of "Audio Out" on the back of your cable receiver; then, connect the other ends to the corresponding color "Audio In" ports on the back of your TV.5 Turn on the power of your TV cable receiver box first. Allow it to run through the boot sequence. When you see the time appear on the front of the cable box, you may turn on the television and check your signal.

    How do I set my receiver to read TV/CBL Dolby Digital. It is a AVR 789


    The Dolby digital signal is outputted only through the Optical or Coaxial socket of the CBL box. you will have to get an optic fiber or coaxial cable depending which cable box you have and connect it to the digital input of the Denon receiver. The Denon's digital input are already assigned at the back. Eg: Optic input might be labeled CD so if you are connecting the CBL box to the optic input remember to select CD on the Denon to hear the cable sound, same goes with the coaxial input.

    Cable company switched to digital, now my Ant A port on the vs-50603 does not receive signals. I can somewhat view the analog signals through my PIP only. other tv's in the house came back with signal 5...


    When the cable company offers you digital cable, you typically need a cable box to unscramble the digital channels. Therefore you need to connect either a coaxial cable from the cable box's RF output, if it has one, or connect 3 RCA cables from the yellow, white and red jacks on the rear panel of the cable box to the TV. Analog channels only (if available) will go straight thru over the coaxial RF hookup. They are not scrambled. Select the proper input source on the TV for the cable box.

    I am trying to hookup a RCA l32hd31 to my stereo receiver and it is not working I see it has only 1 audio out which says use a audio coaxial cable which i have tried and do not get any sound what am I...


    when it specifies 'audio coaxial cable', you need to make sure that is what it is your using and that it is specified on the package. Any other cable will not most of the time work for your needs cause it was not made for that. Cables may look the same, but carry different functions. TV cable will not work as an audio or video coaxial support that you need. Video 1 may work, if you have 'S-Video', try that jack outlet as well. Hope this helped.
