Most of the time, replacing the Signal Board will fix the problem. You can order on from LG themselves at 1800-243-000.
I hope this helps,

All of a sudden my 32" soniq tv keeps saying No Signal to all channels


Use the remote to see if it got switched to another input on the TV instead of where the antenna or cable input is hooked up to. If it is on one of the other inputs where nothing is hooked to you will get no signal.

I have a brand new technika tv 216/54g. It has freeview built in. I have a brand new indoor digital amplified aerial also technika but I cant get it to pick up any stations. Do I need anything else? please...


Hi there,

You don't necessarily need anything else, but you may not have a strong enough signal to pick up the digital/freeview channels using an indoor aerial. It could also be that the indoor aerial is not correctly aligned.

If the signal strength is lower than approx. 50%, the TV may detect them during the automatic channel scan but it wont store them. When the signal strength for any digital channel is 50% or lower it's more or less unwatchable - the picture would be constantly breaking-up or freezing and the audio drops out continually. Trying to scan for channels using an indoor aerial is rather hit and miss. Numerous attempts may be necessary before you get any channels.

Assuming you have a roof aerial, it is far easier to temporarily connect the TV to a fixed aerial point while you run the automatic channel scan. The TV will store all the channels and you can then move it to it's permanent location and connect the indoor aerial. You can then adjust the indoor aerial with the channels already stored until you find a location for the aerial where you have a good signal.

Doing it this way also eliminates the possibility of a fault with the TV and confirms that you are performing the channel scan correctly. If the TV is connected to a fixed aerial point and you are still unable to receive or store any channels, then it's likely that you are performing the channel scan incorrectly or there is a fault with the TV.

Please try scanning your channels using a known working fixed aerial point. If you are still unable
to receive any channels - or you don't have any fixed aerial points - please post back for further assistance.

Hope this helps.

Regards,
BElectric

Tv suddenly shows no audio and no video for digital channles only yet all digital channles are detected durring the channel search


Sounds like you have a bad signal from the antenna or the cable. Unlike analog TV if the signal level drops below a certain level you loose the picture and sound completely. The fact that digital channels are detected during channel search does not mean they have a good signal. Try moving the antenna about.

Same thing... suddenly will not "allow" one channel to be seen


go to tv menu, do an "autoprogram" and it will select all available channels.
You can also do an add/remove channel and manually delete the channels you know you don't have.
You can also change your tv from air to CATV (cable) On cable tv you can still get all the air channels and Fox just the numbers will be different, but you may have a better signal

My samsung tv is not responding to my remote control, actually even when I go and attempt to change the channel from pressing the up/down buttons on the tv it won't respons, some menu screen would come on...


your turning section is not responding to any input, hence needs to be checked by a technician. every thing you have mentioned are controlled by one ic, with its respective voltages.
