TV Tuner I am not able to view any channels after scanning. When switching to live view I receive a message that there is "no signal imput."

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.

Chances are the CRT has expired. In that case I would recommend replacing the entire unit.

If the TV has a digital tuner, then the TV's remote should have an option to scan all receivable channels for viewing. If its an analog TV, then you need to utilize a digital box to allow the TV to receive digital transmissions by changing the analog signals to digital.

I bought the same TV wich is in fact a Seiki TV, see the warranty paper. The television has digital and analog tuners so is able to receive digital channels.Our television receive signal thru a rabbit ear antenna and we had some trouble to scan all the digital channels. We had to change the orientation of the antenna to receive correctly the signals and we had to scan many times. We finally conected the TV to a roof antenna so we where able to scan all the channels of Montreal, north Vermont and north New York areas since we are living in the south shore in front of Montreal. After the scan was completed we conected back the TV to the rabbit ear antenna and the television is working correctly receiving all the stations of Montreal area with a very good picture quality.

Hello
Here is the procedure for auto tuning. Pleas go through it. Connect the antenna to the rear antena socket marked as &% ohms antena and continue.

If you have already run the Auto Tuner as part of the quick setup earlier in this guide, please

skip ahead to "Channel Summary" to continue setting up your television. In Auto Tuner Setup,

the TV automatically scans through all available channels, memorizing the active ones and

skipping over blank ones or channels with weak signals. This means you scan using the

CHANNEL +/- buttons), you will receive only clear active channels.

can add or delete channels from the line-up or prevent any unauthorized viewers from watching

any or all 181 channels.

Press the MENU button

?† To CHANNEL SUMMARY

The Channel summary screen will now be displayed with

the channels set to scan marked with an "?". You can delete

channels from the scan by removing the "?". If any channels

were missed during auto tuner setup and you wish to add

I'm quating these procedure from the manual I've with me, and it is for JVC AV32S565.

This tv has an analog tuner so you will need a digital-to-analog tuner set-top box (assuming you live in an area where most stations have been converted to digital TV broadcast). Whichever tuner you use, the recommended antenna will depend on where you live and how many tall objects are between you and the transmitters. Go to antennaweb.org or tvfool.com and type in your address. Antennaweb assumes an external antenna but is still very conservative in the channels it will identify as watchable in your area. Tvfool.com lists the channels by direction and the antenna type (by color) you will need to receive them. The color rating is based on how far the stations signal travels to reach your location. An amplifier can help you receive stations that are marginal to your location. (Digital signals are sufficient for the TV to tune them in or you get "no signal" messages.)

I hope this helps.

(I'm in a rural area with an external antenna with a signal splitter/amplifier. Antennaweb suggests I will only get the stations ~10 miles away. In fact I get the stations from there as well as the ones ~30 miles away.)

If you have tried autoprogramming and have found nothing it may be a bad tuner. Is your VCR is hooked up via coax or into a video input? If it is hooked up via video and is working but the coax connection direct isnt it will be a bad TV tuner. Easiest cheapest fix is to use you VCR to change channels or get a Digital Cable Terminal from you cable provider and hook it into video or compnent.

The antenna must be hooked up to the converter box. The better the antenna, the better your reception will be.

Not everyone in the country will be in range of digital signals. Digital signals have a shorter range than analog signals do right now. It is possible (but unlikely) that you are not currently in range of any digital signals.

So make sure you are set up like this - Antenna--converter box--Television. Then scan for channels. You should still pick up any analog signals while the box is hooked up, you will just view them the same way you do now, by changing the TV station rather than the converter box station.

You do not need to use an RF modulator if you have a LG DR787T. It will output the program on channel 3 or channel 4. If you have another recording machine, I think you may need to re-scan for the stations.
It is also possible that you need to use the remote to switch from the analog (66 only?) stations to the digital stations.
If using a 787, press HOME, select TV & press ENTER, the channel list menu appears. With the highlight on the top of the list, use the < and > arrow keys to select from: TV, DTV, Favorite, or ALL. This lets your pick whether you want to see digital, analog, favorites with the "HEAR" symbol, or all stations.

THIBSRUS:
I think that there is a selection on the Panny that works much like the TV/VCR selection on a videotape recorder. Your machine is receiving and decoding digital stations, as you stated you can see them on the menu screen, but is not passing them through to your TV set for viewing. To use the Panny as a tuner for live TV shows, or actually, programs currently airing, you have to tune the TV to channel 3 or 4, or, if using the Red/White/Yellow connectors, the proper video input selection, AND turn the Panasonic on, and have it sending the programs it is receiving out on the antenna connection or the video/audio out (RWYellow) connections. It is really a matter of selecting, on the Panasonic, whether it passes through the antenna signals, or the digital signals that is is receiving.

if you scan down below channel 2 doesn't video show up? otherwise there should be a input / video button
