Check 2 items before going any further:
-- Make sure you have a good antenna signal by connecting it to another tv set.
-- Make sure you've switched input source of your tv to RF Antennae.
If the steps above didn't help your problem in TV tuner (assuming you're getting signal from other sources, i.e. DVD, VCR, etc). Have the unit serviced.

Problem is probably with your cable box as you have confirmed that the set is working by using the dvd player, that is unless you have a bad cable for the cable box.

I have just acquired a new lg tv as a free gift from sky. My problem is u can't tune it in either auto or manually. I don't have a aerial just hdmi skybox

You will not be able to tune in TV stations unless you first have a TV antenna installed. Once connected to a working antenna the set should find stations easily enough ?

But you do not need to tune anything in to use it with your skybox -simply connect the skybox to the TV using an HDMI cable (available anywhere that TV's are sold) noting the number of the HDMI socket that you plug in into on the TV. Then, using the TV's remote, set the TV to input signal from that input (HDMI 1 for example) and you should be fine?

My tv does not recognise 90hd, 76. it goes 72,73,then 91, 92,93, 94, 99,I try auto or manual tune the stations do not show. also have digital aerial connected directly to tv and tv shows no signal

Hi Jonathan

Sounds like you are in Oz ,,, like me

Not sure where you are compared to your signal & it's strength
Digital antennas are really no different than the previous analog tv version. Slight Freq Difference. Just a ploy to sell more antennas. I'm still using my old analog antenna and I pick up all my channels. 7,9,10,sbs,abc.
Occasionally I get a weak signal that causes pixelation. Usually when storms are near.

I do have an Antena Amplifier located in my TV Junction Box near the AC Power Junction Box in my Garage. (Rather than the Mast Head Amp that is on antenna pole).
This provides an easy assess point for TV & Phone cables.
There are various signal booster amps available.
Mine is shown below.
But there are others that could be located behind your TV.
Depending where you are.
Main Cities are usually a horizontal polarised antenna,
Country are vertical antenna. Most people don't notice.
This helps to keep city areas from interfering with small country towns. Keep this in mind if you travel with a caravan.

You could try a simple antenna cable to the TV with open bare wires at the other end with a couple of rods attached.
Just to prove whether it's your roof antenna or wiring.
Rabbits ears will usually pick up enough of a signal to prove the point.
Unfortunately with digital you will have to retune the TV to see if it's getting a signal. Auto Retune. As there is either a signal or none. Unlike the old days of seeing part of a ghost signal.

Then you will know if your TV & it's tuner is working OK.

There is an App I have on my iPhone which helps.
It indicates what direction & distance the transmitters are from your location. AntennaMate

Hope this Info Helps

What causes pixelation only on digital 9 TV and there subsidiaries

Pixellation is a weak and noisy signal coming in. Digital HD needs a good signal at the antenna socket on the back of the TV. You need to have good quality quad shield coax cable down from the antenna, and preferably crimped F-connectors at each plug and socket. You may even need a new digital antenna if you are making do with an older analogue one.

Your other stations will also improve.

You need a better antenna, or relocate the antenna so you get a better signal. My TV did the same thing until I put the antenna close to a window.

Just bought a house and moved in. I have plug the TV into the wall antenna socket and the TV comes up with the message 'weak or no signal' what could be the problem?

Hi, congratulation on your new house!

The problem is obviously from your antenna. The TV is not recieving any reception from the antenna and that is why it is displaying 'weak or no signal'.

Cross check your antenna connection and make sure the antenna wire is intact.

Also, most antenna's come with a booster. The booster makes reception from the antenna very strong and the TV would be clear.

Lastly, is this a new antenna or were you using it in your old house?

Please give me a feed back.

Yours sincerely.

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: . 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 or 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.

Lg 42' lcd cant get video signal i can get sound and menu pictures all come up. but no output from cable or ps3

I guess your either using the scart socket or the HDMI socket. You have gone into the menu and changed your input source to either HDMI or Scart havent you? Does your TV aerial input work when switched to Antenna on the input source menu. If these dont happen then you have a faulty main pcb.

Keep getting a low signal text at the bottom of screen on one of our tv's and on the other we have sc4 instead of C4 on number 4 guide slot. No matter how many times I re tune it does not correct these...

Your signal strength is being split in half by the r.f splitter(aerial socket).
You might want to try and buy a cheap 10db signal booster /r.f amplifier/antenna amplifier this will help to boost your signal before it is splitted.
You`ll install it between the antenna and the splitter.
All you need is the booster and a short r.f/antenna cable extra.
Hope this will help. Merry Christmas
