Just for info my channels like food network and Dave are intermittent at the moment normally quality is solid 100% strength 50% but some mornings and night the quality is up and down like fiddlers elbow 60 20 30 percent that's on a youview box then it goes steady agin i live in Selsey with digital airel and no booster. I am aware that they are working on it at the moment I have a installer check time airel and its fine with a fancy bit of kit not the 10 quid airel checker from screw fix.

Brian : Thanks for the info on the Sony model in question, this really being for notebook purposes as well as enabling me to check the service manual for same to find details of tuner fitted into this model as I do find what you have reported to be slightly puzzling as far as the Panasonic is concerned, as in my experience anyway Sony has never excelled to any great extent over any other well known brand and especially Panasonic, albeit that the latters signal strength / quality indicators do have rather lively extremely fast responses to changes in the signal levels over that seen on many other sets, some of being rather sluggish meaning that a signal could dive up a down and yet it would appear to be stable, mabye the latter is not such a bad thing though!

By the way, I would take what you have been told by the digital hepline people "if" thats whom you were talking to? with a proverbial pinch of salt, as although what you have been told can in many instances apply in other cases it doesnt dependant on what is involved, therefore the only thing I would suggest you do is try and verify if anyone else in your locality are also experiencing problems with reception at around the same time as yourself, of course making sure that they are viewing the same programme channels as well as ensuring that they are viewing whatever from the same station, as checking back on your postings I cant say I noticed you having mentioned where you are located, this info being important when evaluating causes of reception problems.

Thanks for the feedback Guys, We are situated at PO7 6BE, waterlooville area. We have never had an issue with the Sony tv on HD channels since HD started in the meridian area. However i'm beginning to think that it was related to the transmitter work as since 15:30 yesterday not had a problem.im guessing the work has finished or they have gone for the weekend. If it was the transmitter work puzzled as to why the Panasonic did not like it but the Sony was fine, albeit that john said Panasonic tuner's are quite sensitive. As far as checking with neighbours nobody we know near us has a HD TV. Will monitor it over the weekend and see what happens. digital helpline told me the work in progress on transmitters updates on a Monday, hopefully rowridge will be work free enabling me to make a better judgement as to whether it was likely to have been the transmitter work causing the problem.....

Paul: It should be mounted vertically, particularly as you've had someone out to it.

In your location I am very surprised that you have an aerial in the loft.

If you continue to get further issues give me a call and I can pop over and test it.

I am local to you and an RDI approved installer.

Brian: Although this is neither here nor there if your reception has previously been OK prior to the commencement of the engineering works at Rowridge, but now is known you are located at 20 miles away from said transmitter can you confirm that your aerial has been mounted vertically?, the purpose of being to enable you to obtain maximum signal strength from the three commercial muxes and which only radiate at 200kw on vertical polarity, whereas 50Kw on horizontal.

By the way the BBC and ITV stations radiate at 200Kw on both polarities, the other point being that in cases where the signal is intermittently diving downwards then its not so much turning the aerial than can "sometimes" help, but moving its mounting position slightly to the left or right of its present location.

Although as having previous said, I wouldn't alter anything as yet but wait until Rowridge gives the all clear.

P.S: You aerial should be vertically mounted irrespective of anything else that may have been discussed.

@Jamie, thanks for the offer will keep it in mind.

@John, yes can confirm aerial is vertical, from memory I changed to vertical when HD switched on. It is Looking more and more likely that it was the transmitter work, as I said previously no problem after 15:30 Friday and had it on HD today since 07:00 and no signal probs at all......if all is well till Monday may tell J.L. to cancel replacing it.

Hi, I reported recently having problems with some channels. I now have NO channels. The EPG is working ok. I am in the SO17 area. Before I do a reset, is there anything else I should do?

I've fixed the main problem by resetting the box. Still having problems with the ArqA channels, though.

I see that you had this same problem a while back.

It may be that your reception is marginal which could be down to many different things.

Type of aerial
aerial location
age of aerial
age of cable

have you tried turning your aerial from horizontal to vertical?
