Dave: I think you have too much signal. Remove any boosters or amplifiers; if that doesn't help (or there aren't any) add an attenuator.

My Thomson Freeview box in the kitchen lost all BBC last night. Have tried re-scanning with connected both to main house aerial and it's own loop aerial but still not finding them. Thomson Freeview Recorder normally connected to house aerial has no problem and I'm not going to re-scan that incase I lose BBC on that one!

Sally - does/did it still have BBC1,2 on button 1,2 and the rest where they should be, but show "no signal"; or did it not have anything on 1,2 but still got ITV on 3; C4 on 4 , 5 on 5, etc?

Have you retuned from scratch, or Add programmes?

Nothing else connected to incoming aerial when you tuned?

Do you know which transmitter you use? Feasible it is faulty, and might differ from one TV to the other if different aerials.

Is your box on the list of boxes that won't work after various changes?

Hi Steve, Absolutely nothing on 1,2 or any of the other BBC channels, radio included. By Thomson DTI 1000 doesn't appear to be on the "won't work after" list. Got loads more "Adult" channels though! Their drama's aren't quite up to BBC standard lol!

Sally - try rescanning "Installation" or "All new" options, using just the (proper rooftop) aerial into the box and box into TV. Other kit can confuse.

Watch as it does it and note which Channeel numbers things happen at. That will confirm what you are receiving.

If still no go, work thrrough this

My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | - independent free digital TV advice (LL145HD)

Prior to digital switchover I had intermittent picture breakup, pixalating and sometimes loss of signal. I understood that the digital signal was going to be substantially increased at switchover and assumed these issues would disappear. Sadly inspite of numerous re-tunes I still have the same reception problems! Has the signal actually been increased? I have a recent roof arial and live in nn4

I have a new Sony HD tv which showed the HD channels listings but when selected there was no service/pic.
I rang Comet who said do a factory reset since then I get no HD channels/listings for the HD channels I have tried several times and the result is still the same

I should have added I am in the Sandy Heath reception area and on all other channels the levels are 100%

At a guess, the TV came having done channel selection somewhere else where there was a HD signal, but where you are there isn't.

So when you reset the listing disappeared too.

Are you on the main tx? Not a local relay etc.?

Stick your postcode in top right and see what Brian's predictor link says.
