Very poor picture quality on LG 42" SMART TV 18 months old


This is probably due to poor quality cable or connections from the aerial. Digital TV needs better quality in both (F connectors and quad shield cable) than analogue TV did.

If all that is good then you may need a better aerial or even a signal amp.

Panasonic User Manual


as far as I am aware, you need a standard analogue aerial to receive Freeview, not a dish. The aerial plugs into set top box, which is connected to tv by scart. Freeview is different from Freesat

Hello .i have a lg tv which i purchased in 2008 and only watched videos,i now want to watch tv i have tried auto tune and it only finds 3 vhf channels and none digital.it has preview built in but i can not...


if it has freeview built in its usually programmes itself try turning it on and go into the menu and there should be an auto tune function hit that and it should tune up but remember it needs to be connected to an aerial if it still says no signal try moving the aerial, getting a booster for the aerial they usually plug into the mains then into the back of your tv and you plug your aerial into that to boost the frequencey if that doesn't work then you might need to think about getting a new aerial but you can get 1 for under £30

Most of the channels breaking up despite auto retuning


could be one of a few things,
low signal strength, aerial out of line with transmitter.
bad coax connections losing signal strength.
coax broken inside, or old and not low loss.
Get the aerial checked for direction, half a degree out of line over a few miles and you will lose a lot of signal strength, as will old coax (aerial cable) and if you are using an unshielded coax you could be losing signal strength through the cable itself. Replace the connecters and try to use a straight run of cable instead of having joins in it as these joins, even if using connecters, will cause a weak signal. If yiu are running more than one tv off your aerial, invest in a booster.

Tv with built-in digital tuner not receiving any channels


Is your outdoor aerial a proper freeview aerial and are you in a strong or weak signal area.You can check here:http://www.stevelarkins.freeuk.com/freeview_digital_tv.htm
Also check your connections as the coax may be shorting with the braid or a bad connection.once checked try ordinary channels on upstairs tv and if ok retune all your digital channels.
This can be due to a few problems.Firstly make sure your aerial is pointing in the right direction as beam aerials attenuate(disregard) signals which are not pointing directly at the aerial.
make sure you are using good quality 75ohm cable i.e rg6 and connections are good and not shorting out.
The length of run of the cable will also affect the signal as will any splitters or joins in the cable.
If you know the signal is good in your area then it will be down to the aerial,cable terminations ,aerial position or a combination of these.
If the signal is poor you can either...Buy a high db gain arial which will amplify the signal and or a masthead preamp which will again boost the signal.
please note that if your aerial is not pointing in the correct direction then any boosting of a bad signal i.e ghosting...will only make it worse.
try starting from aerial direction then connections then a high gain aerial and or booster.

Yah i have a dynex tv and a Asus desktop comp and my tv says no signal when i plug it in i dont know what the problem is


Is the dynex tv unit installed inside the ASUS desktop computer?
The TV receiver needs an antenna/aerial connected to the TV receiver to receive TV signals, without it you will get no or weak signal.
Have you connected an antenna/aerial to the Dynex TV unit?

Tv-- signal strength normal but signal on all channels "blipping" down intermittently causing freezing of picture. Have replaced aerial with high gain antennae together with aerial cable and...


When ever the picture freezes intermittendly the problem is usually poor connection on the signal line (antenna or connection on tv) or poor reception. Could be the tuner if the tv has one.To eliminate the tuner possibility try anther tv set if possible.
If you still cannot figure out the problem,let me know what kind of set up you have connected to your tv set.
Do you have a satellite or cable box and if you have splitters.
