My lg tv does not recognise antenna socket/signal.

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?

Hi Jonathan

Sounds like you are in Oz ,,, like me

Not sure where you are compared to your signal & it's strength
So...
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
Cheers

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.

U are using a Antenna for free AIR tv correct?Yes?Get a better antenna like a digital antenna should solved this problems,now a day a digital tv and a digital signal pretty strong this day,regular antenna will have this problems,because it tune into a radio waves signal too.

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.

Hi
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

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.
