SOURCE: broken coaxial

If you are comfortable doing some small repair work, you might be able to fix this with stuff you have laying around.

All you need is:
1 - 8" piece of coaxial cable with male connector on one end
1 - set of RCA cables (Red/White/Yellow)
1 - coaxial coupler
2 - small wire nuts

electrical tape

Take the back housing off of your TV. You may have to unscrew the small nut holding the threaded connector to the TV. This threaded connector should connect to the motherboard with a male RCA prong that should be soldered to the component on the motherboard. You will need to carefully cut
& remove the old soldering & wiggle the connector off. This is the hardest part, but it WILL come off with a little trying.

Now get your coax cable and strip off about 2" of the black outside housing ONLY. Your solid copper` interior cable should be protected by a small plastic coating which is covered in braided wire. You'll need to be careful not to cut the braiding off. Untangle the braiding down to where your cut stops and try and get it all on one side of the cable so you can twist it all together and make a nice wire. Now strip about an inch off of your interior plastic sheathing to reveal the small solid copper wire on the very inside.

Get your RCA cable and cut about 6" off of the one yellow side. Follow the same process above to get a braided sheathing wire and a solid copper wire. Attach this yellow wire to the coaxial cable by twisting the two braided wires together and the two solid copper wires together. Use your wire nuts & electrical tape to secure your connections making sure none of the wires can touch each other.

Connect the yellow cable's male prong into the component on the motherboard and attach your coaxial coupler to the male end of your coaxial cable. If you saved the small nut from earlier, you can re-attach this new coupler to the housing on your TV. Screw your housing back on the TV and you should be good to go.

SOURCE: Channel Scan on my Philips 26" TV only finds the local channels.

Hi.

you should go into your tv's setup menu and go to the tuner settings and make sure it is set to CATV (cable tv) and not Antenna/Air also splitting a cable to many times can cause the signal to weaken and gain a lot of noise/distortion that could be an issue that can only be solved by having the company come to the house and do a test ALSO when your in the tuner menu in under your tv's setup menu try adding a non local channel manualy and then see if the tv will tune to it, if so then you might have to add them manually at the worst... my guess is that it is not set to CATV/cable tv hope this helps and if not i hope someone else can.

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.

Hello

On alot of cable boxes there is also an "ANT IN" that you can bring your rooftop antenna in to. When you turn the cable box off, it passes the ANT signal to the tv.

I hope this helps you out

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 GPX model tvwb534 connecte to an indoor rabit antenna doesn't work?


You either may have the set on Cable setting or the signal is too weak for the set to pick up the channels---indoor antennas have a very limited range and many channels have ended on air broadcasts completely

How do you connect the antenna and get channels to work?


First make sure that your Input is TV. Use the Input button on the remote (to the right of 0) or on the side of the TV (lowest button). To watch OTA channels, after connecting the appropriate antenna for your location with a coaxial cable to your Antenna In port, press Menu then use the arrows to select the Setup submenu. Press Enter to access the submenu and select Installation. Then select Terrestrial and then Input Configuration. Here select Antenna as your input. Press Enter to save. Then scan for channels by returning to the Terrestrial sub menu and select Channel Program to scan all available channels.

Since digital signals are either sufficient for your tuner to interpret or give No Signal, you need to select your antenna and point it with care. Go to anntennaweb.org or tvfool.com to get information on the stations that you should be able to get in your location. Antennaweb assumes an outdoor antenna but still gives a conservative list of available stations. TVfool gives stations depending on the color code of the antenna (indoor, outdoor, amplified) and their directions. If you are sharing the antenna signal with multiple TVs, you may need an amplified splitter. (If you do have an amplifier, you may want to test removing it from the line and directly connecting the 37HL17 to the antenna. When amplifiers get damaged they can turn into signal filters which block the signal completely.)

If you have the correct antenna, check if another TV receives the stations. If so, you may have a bad tuner on the TV. (Some TVs have better tuners than others and pick up the stations even with lower signal strength.)

I hope this helps.

(I use an outdoor antenna and antennaweb indicates that I should only get the stations from 10 miles away. I actually get those from 30 miles away as well. When I set up a neighbor's TVs with indoor antennas, one only gets the stations 10 miles away and the other gets the stations that are 30 miles away. The two antennas couldn't be rotated to the same direction.)

How to connect a philips antenna to a trutech tv


Unplug your television and turn the set around so the back of the set is facing you.

  • 2 Disconnect the antenna or cable connection from the television's "VHF," "Antenna In" or similarly worded port if it is connected.
  • 3 Examine your splitter and notice one end of the device has a coaxial port while the other end has two coaxial ports.
  • 4 Plug the coaxial end of the television antenna into one of the two coaxial ports on the splitter.
  • 5 Plug the coaxial cable coming from the cable television connection outlet into the second coaxial port on the splitter. Use the port next to the one you used to plug the television antenna into.
  • 6 Place one end of a 2 foot piece of coaxial cable into the single coaxial port on the splitter.
  • 7 Plug the other end of the 2 foot piece of coaxial cable into your television's "VHF," "Antenna In" or similarly worded port.
  • 8 Plug in the television set and turn it around so the screen is facing you.
  • 9 Use your television's remote control to access the "Menu," "Setup" or similarly worded function. Or press the "Menu" or "Setup" button on the front of the television.
  • 10 Select the "Channel Setup" or similarly worded function. Set the Input to "Cable" and perform an "Auto Scan" to locate all available cable television channels.
  • 11 Select the "Channel Setup" or similarly worded function, then set the input to "Antenna" and perform an "Auto Scan" to locate all available broadcast channels. Your television will locate both broadcast and cable television channels.
  • 12 Scan the channels on your television to make sure all available channels have been found. If you are missing any channels that you know you should have, manually program the channels into your television using the "Channel Setup," "Manual Channel Setup" or similarly worded function.

    I installed a coby tv in my RV. Auto scan worked great for a year. Today it picks up no channels at all. Everyone else in RV park has 20+ channels. The scan performs everytime, but picks up nothing


    If you've tried all positions with antennae, booster switch is on, and are sure you have all settings on TV correct, try running an alternate cable directly from antennae head to back of current plate where your co-ax from antennae is attached. That will tell you if you have a bad cable or connection from antennae to plate inside. Just get a piece long enough to go through door or window to current spot where connected. If that doesn't cure it, then it's a head or booster switch problem. You can even by-pass the booster and go direct to TV to see if any better.

    There isn't a tv signal on that coaxial cable. The other end of it is not connected to anything with an active signal. For example an indoor antenna, or an outdoor antenna, a cable TV company's active TV source (that you are payin for), or a satallite TV company that you are paying for them to turn on, also TV's do not have a built-in satallite tunner to tune in those sattallite channels, you have to use that company's external tunner box. No tunner box = no channels. Even U-Verse No Tunner Box = No TV.

    Any TV that has a Coaxial input can connect directly to an RF antenna. If this person lives near a large city, its likely they will receive more channels than if they live somewhere remote. Perhaps an antenna with a powered Signal Booster will improve the signal. Neither are included so I think Radio Shack has a good selection.
