If you have all 3 tv's in the one house and on the one antenna then it sounds like you have been subject to either a lightning strike or a large static discharge onto your antenna. What this means is that the tuner packs in the back of the tv's has been damaged and will need to be replaced. However as you have said in your question they do work using an av input. This will be your cheapest option to get them working again. Buy cheap vcr's for them and connect via av cables, as the tuner modules are expensive to buy and even more so to have fitted.

On my Techwood it as built in freeview but every other channel is right except bbc1 and bbc2 both channels say bbc wales,How do i get them back to bbc1 and bbc2 please PLEASE HELP.THANK YOU.


What you need to do is retune the TV, but when it is finished look at the regional settings. Or if the regional option is available before retuning, retune selecting your area so then you get normal BBC channels. It's likely that at the moment the channels for BBC are located at the very top end of the channel list say? - channel 800+.

You are clearly picking up signals from many transmitters. With regional settings you can change it to the area you live in.
But you will have to take into account how good your aerial is. Otherwise the signal quality will not be good on same transmitters. So the set may only suggest those with the best quality signals.
ITV stations might also change.
When done it will move the channels you mention to the top end of the guide, to 800+.

Note many HD channels have no regional options. For example here in Yorkshire we only get ITV Granada and not Yorkshire TV on the HD channel for ITV1. And BBC1HD does not show any programmes when local news comes on.

My humax won't;t record bbc channels. I have tried retuning the tv.


This could be too much signal thanks to the Freeview retunes going on. Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range. The signals for BBC and ITV are among the strongest ones broadcast. If they are now at a point on the aerial's range where they are too strong for the TV then the tuner will over-saturate. The result is the same as no signal.


Have a look online for a Variable Signal Attenuator. It's a device that can be added to a aerial signal cable just before it goes in to the tuner. The adjuster allows the signal level to be reduced. Watch the TV's signal quality and signal level displays if it has them. As signal level (power) reduces you'll actually see signal quality increase. If you go too far then quality will start to go down again. The optimum point is where quality is highest.

Why can I not receive ITV channels

The result is the same as no signal.

A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:
Splitters amplified splitters and attenuators

It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

I think you need to get Sky because it will give you 100% coverage of all terrestrial channels. You may need to retune the television otherwise just get sky
