Good morning Susan, Sorry to hear of your problems. Just a few questions - how new is the installation? The reason for asking is that old i.e. more than say 10 years, cables can get moisture in them which will reduce the slowly over a long period. It seems that your signal is getting weaker and that may be the cause. The solution is to get an aerial rigger to replace the . You may in addition need a head to boost the signal. I have two LG TVs and they both work very well.

Hi Richard - thank you for your input. You may have a point since I live in a flat and the installation is probably nearly 20 years old. I will ask our Estate Manager to ask for an engineer to and inspect the wiring and also check the type plus whether a new is needed for the main aerial. My neighbour upstairs has a different model of LG but is experiencing similar problems though not so drastic. Last night was great since the picked up to 70 and the set behaved itself. I it stays at that level since I want to record Montelbano tonight - my favourite series.

lj.jewiss@hotmail.co.uk: Its not really possible for anyone to be able to give assistance for queries of this nature without having knowledge of your location, this in the form of a post code or one from somewhere nearby (a shop etc) as only then can the levels expected at your location be assessed as well as details of the transmitting involved.

We have also experienced problems with major drop-outs and the TV squawking it's way through programmes, absolutely useless in the morning.
We have changed nothing and its affects ALL or TVs.
MUST be fiddling with the strength.

I did the today. The tv seems okay. However my Sony recorder has a 'sort of' a problem! Prior to this switchover I could not receive the HD through it, the would just break up. It wasn't a great hassle I would record off the 'normal' channels. Now, since the changeover the HD channels don't appear on the EPG. Is it worth going through the process again? I presume I am never likely to receive a good HD through it.

Update to the above. I did do the rescan again this morning on the recorder (this time after unplugging it - previously I only ran it without the connected). This time it has picked up the HD , but they are still completely unwatchable with the completely broken up.

ann Yilma: As you are located at a distance of only 5 miles from the you have to beware in case the level of received is slightly excessive for the TV's tuner, as this will give "exactly" the same signal indications to that of a signal that's too weak.

You have not mentioned anything regarding the being used, but for a carry out another retune using a set top aerial, should you be able to borrow one!

Further info dependant on findings.
