Turn the auto tuning off, and manually tune in all the channels you know that you get.

SOURCE: Quasar VV-2001 TV/VCR combo - msg: Check Antenna Cable Connection

Check first the antenna using another TV. If there is no other TV available, check using an ohmeter. If you are 100% sure tha the antenna is ok then the antenna connector on your Tv is not making a good connection to the antenna plug.

SOURCE: Toshiba D-VR650KU can't "see" digital channels

On the Notification screen with Cable highlighted I found that left clicking on Cable gave a drop down menu with TV on it for selection. The manual says that while Cable is highlighted, use the up or down arrows to get TV to be an option and then select it and Yes and enter. Hope this helps. I have other problems with my monitor on Line Out, the screen oftens turns blue indicating low or no video using Line 1 or 2 inputs.

SOURCE: When auto tuning my LG

Hello,

The ABC channels arrive on a different Harmonic than Analog signals; specifically the third Harmonic. When you auto tuned, the auto tune chip looks for stron analog channels on the first harmonic and any other strong signals. However the LG model is notably poor at capturing 3rd Harmonic signals.

Harmonics are different frequencies where the same signal can be captured. Making this overly simplified: a frequency multiplied by 2 is a harmonic and that multiplied by 2 is also of the same harmonic; inversely dividing by 2 and 2 gain and so on finds harmonics down in light wave frequencies.

You may be able to manually tune these ABC frequency channels manually (I do not know, as I live in the US and have no direct experience with this) and then add them in one by one. But, using the Auto Tune feature again will wipe those out. The same thing happens to other weak signals, which harmonic is actually (its on an offset carrier wave).

I just read of a man who built an improved antenna and put this in his attic and received ABC channels quit well. A decent understanding of Antenna physics is required, but it only took up 1.5m wide by .8m (sic) long. In a nutshell he improved his basic antenna by building his own more sophisticated antenna.

Shopping around and asking in the shops should get you an antenna add on that will work for you.

As I stated before I live in the US, and we don't have this, but I and others here at fixya have various experience in amateur radio.

I will ask a friend of mine who lives in Australia to confer with me on this problem of yours so he can add some value to our response to you.

Regards,
Worldvet

SOURCE: LG TV loses channels when turned off

Is your location prone to power surges or failures? Try plugging your TV into an uninteruptable power supply (UPS) (battery backup and line voltage conditioning). If that doesn't help, I would be suspect the unit has a problem with the internal memory.

I hope this helps.

SOURCE: New LG 32LD350 - Allowed TV to auto-program

When you are auto tuning the system will not store a channel which is week by its standard ( at least 60% signal strength ) This done to avoid grainy picture and hissy sound.
You can go into manual tuning and store it.

Why does my tv continually drop antenna tv channels. I have to rescan tv several times a day

Assuming that we talking about digital channel could be couple reasons. First- too small antenna or in wrong location. Usually at evening, night hours there is less interference from cars, running electrical equipment etc reception is better. Far away stations reception is also better at night. Trees, houses etc also affect reception. If you in USA you can use site: antennaweb.org to determine correct antenna and direction to receive channels in your location.

I have tried to tune my tv but its still not going even when i put the cable in the right place.! it just shows no channels at all.! what can i do?

In your "Channels" menu, you should have the option of "auto tune". Once you've plugged in your antenna, cable cord, select this option. Before doing so, unplug your tv ONLY and let it set for about a minute. Plug it back in, turn on, go into Channel Menu and select the "auto tune" option. This may take a while, as newer tvs have several hundred channels. This will auto tune your tv to the channels received through your selected device\cable. You may consult your user manual for further assistance. I just did this with my tv a couple weeks ago and its very simple. You will also be able to "delete" channels that do not come in well, or not at all i.e. The "ant screen" etc.

Cant retune through dvd player

Sounds like a few things going on here... Your indoor antenna for one is probably not making it easy for you as an outdoor antenna will work a whole lot better. This is why it open picks up half the channels and they are pixelating. Also you may have faulty rf leads. Replace these.

How to tune channels first time when you purchase a new Sony Kdl 32EX600 LED tv?

Hello
Do connection to the antena if you wants to set the TV auto tuned.
During this initial setup, you can perform the following:

1 Select the language for the on-screen display text.
2 Select HOME or Retail mode. [Here you have to select "Home" mode if the set displays "Retail"

3 Connect cable or antenna, then select OK to run Auto
Program

• If you have cable and antenna available, please connect cable first.

• IMPORTANT: Auto Program is only effective when cable or

antenna is connected. If you cancel Auto Program before completion some channels may not be
available.

4 Auto Program will scan for available channels from the signal source directly connected to

the TV's CABLE/ANTENNA input and may take sometime to complete the process. Follow
the help text provided on the screen to run Auto Program.
OK.

I got an American model of LG. i can not tune it by auto nor manual can you please help

You can get a manual here: http://www.lg.com/us/tv-audio-video/televisions/LG-lcd-tv-32LG30.jsp . Click on the Support and then on the right hand side look for User's Manuals. Since the TV has a tuner for ATSC, NTSC, and Clear-QAM, the next question is what is your signal source? (analog, digital and unscrambled cable)

If you are using OTA, make sure that the input is set to Antenna. Use antennaweb.org or tvfool.com to check the direction to point your antenna and the appropriate antenna for your distance to the transmitter. antennaweb assumes an external antenna and is very conservative in the list of channels you should be able to receive. tvfool gives the stations available with different antennas. If you have several tvs connected to one source, you may need an amplifier in addition to the splitter. This also can help marginal signals come in since digital is either enough for the tuner to resolve or no signal. (Check splitters and amplifiers if you suddenly can't get a signal that you used to receive. Also check if the antenna has been turned.)

Menu > Channel > Auto Tuning or Manual Tuning. If Lock System is active, you will need the password. Auto Tuning only searches for digital or cable channels. The manual tuning option should provide the signal strength as well for digital stations (as well as letting you search for analog signals or all signals (digital, analog, cable).

Use the input Cable for coax cable connections. Other inputs will not allow you to search for channels since they are meant to be controlled by the set-top box feeding the system.

I hope this helps.

Describe how to program channels on lg tv

Very simple -
You will need to find a feature that says 'Auto Tune'

This first will ask you to select between:
1) Regular TV - off air antenna - connection
2) Cable TV - connection
3) DSS TV - Connection

If you aren't ready for digital TV with your antenna or cable you may get very few channels.
