Good morning Susan, Sorry to hear of your problems. Just a few questions - how new is the aerial 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 signal 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 cable. You may in addition need a mast head amplifier 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 test and inspect the wiring and also check the aerial type plus whether a new booster 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 signal picked up to 70 and the set behaved itself. I hope it stays at that level since I want to record Montelbano tonight - my favourite series.

recd a message to retune as tv listings had been updated - did so yest 21/9/12 pm no initial probs. however today had lost some itv progs so retuned again have now lost all progs ! have also spoken to relatives who live 8 miles away and they are experiencing the same problems - can u please let me know what the problem is after reading revious postings it would appear that this is quite widespread issue and not the fault of 'old arials' as suggested !!!!

11:26 PM 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 signal levels expected at your location be assessed as well as details of the transmitting station involved.

We have also experienced problems with major signal 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 digital TVs.
Crystal Palace MUST be fiddling with the output strength.

I did the switchover today. The tv seems okay. However my Sony Freeview HD recorder has a 'sort of' a problem! Prior to this switchover I could not receive the HD channels through it, the picture 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 signal 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 aerial connected). This time it has picked up the HD channels, but they are still completely unwatchable with the picture completely broken up.

I have a samsung tv with freeview which has been working well since the re tuning when se12 9ab went digital.However recently I have had to retune on a number of occasions because all channels have just disappeared due to 'weak or no signal'. When it happened again on Saturday 22nd sept I tried re tuning but cannot pick up any channel.It is now monday 24th sept and still no service. Siganl from crystal palace is supposed to be working normally. Please advise. I am paying a licence fee for nothing at the moment.

ann Yilma: As you are located at a distance of only 5 miles from the station you have to beware in case the level of signal 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 aerial being used, but for a test carry out another retune using a standard set top aerial, should you be able to borrow one!

Further info dependant on findings.
