Hi jb 38,
i am not sure if I have that type of radio, i will have to have a check. I do know the next door do get there tv and phone etc from virgin, could this equipment be causing the issues?
I will try and find a radio to carry the test out with, think i will have to pop round next door again and ask him the get the virgin media guys back to check out his system again.
Thanks again, is there any ideas on shielding etc? Tin foil?

regards
Rob

Hi All,
Just been round to next door and they are having some issues with there TV reception through there virgin media box which looked like an older model, however these days they all look a little retro so could be new ish. The only other things they have is a phone and base station which is about a foot from the wall however they did switch that off for two days and no joy and a virgin-media super-hub like mine in my house and there's is very close to the wall at the height of about my TV on the other side of the wall.
After returning home i have read something somewhere on the internet that WiFi can cause interference on TV's, Has anyone else had experience of this ?
Anyway they were very helpful and i have asked them if they could get the virgin media engineer back to check out the problem as it seems to be with the virgin installation to me and they have agreed to do so.
I am also going to contact them directly as i am also a customer for phone and internet.

Kind Regards
Rob

rob: Going by that said you have really done as much as you can on this issue, although the problem as I see it is that the Virgin engineer who comes out to check your neighbours installation "might" not find anything wrong with it, nor is he (or she to be PC) likely to be carrying around the gear necessary for detecting it.

To be perfectly factual about it, about the only positive way of determining if your neighbours equipment is responsible for the problem or not is by them temporarily cutting the power supply to the equipment being used whilst you carry out a C60 check on the Sony.

We had web chat with virgin today and they said no it cant be the router different frequencies, i said yes i understand that however something from your company is making the noise as next door have a pile of virgin kit next to the wall. They then suggested that if may well be EM interference and i should move the TV and here's the best one maybe buy a new TV. Anyway they said next door would need to call them in, which they have said they will do.
I bet you can imagine my response to buy a new TV!!!!

will keep you posted.

Rob.

Rob : What you have reported as far as your contact with Virgin is concerned is not really anything different from what I expected that it would be.

Keep us updated though!

Rob : Rob, I was awestruck to read all your posts, I've had exactly the same problems as you, and especially in the last month or two. I live in Bucks, but apparently we are under the Oxford signal whatever its' called too. Channels have been pixilated and broken up for weeks, and yesterday I lost lots of them to black screen. Bought new digibox and started off ok last night, but thismorning it's worse!! Got nothing really except BBC1. I retuned the old one yesterday and I went from about 70 channels down to about 10. Repeated and it's the same. I'm as angry as you! Any luck yet? (I read all your posts).

@ Rob,
Did you try the tinfoil shield thing? Seeing as the new TV downstairs works all digi channels fine, doesn't that mean the ariel's fine? So it must be something wrong in my room upstairs? The router is downstairs, the only thing is my TV is backing on to next door's bedroom wall, maybe they have equipment backing on to mine? Would that be it? I'm confused though because it's not ALL the time, just most of the time, and this new box I got is only a £20 one from Maplins. The message I get is 'bad or no signal.'
Any help please? I like to watch food network,Al Jazeera and RT news, and they have all not worked properly for weeks and weeks. But sometimes they do.WTH?!

Just read this post above, but can this be it when it's been happening for weeks/few months already? (Our neighbours actually haven't been here that long. I'll have to ask them if they have equipment behind my wall.)

Hi Caz,
I think my issue is a little different to yours , i have all the channels but only some are effected by this interference issue mux 60 channels. If you have another TV ariel point you could try that if they run off the same Ariel or use a lony ariel lead and move it away from the wall to see if this improves it. I only know it is coming from next door as i have moved my tv away from the wall and the problem stops.
The easiest thing would be to try and move it away from the wall or pop round and ask. Have a look on the signal quality and strengh meter on the TV, you may have a weak signal.

Regards
Rob

rob: I HAVE FOUND THE ANSWER!!!!
Thanks for replying, my hubbie just told me that he's been turning off the booster thing in the sitting room every night and that is exactly when I lose the picture upstairs. We live on the very edge of the Oxfordshire area (Aylesbury) but still should get good signal.Apparently. When we had the new digital aerial fitted a few years back the guy also put in a booster thing where the aerial comes into the house behind the tv in the sitting room.It goes from there into the tv in that room. But when I found this out, I got him to test it, as like I said, he'd been turning it off every night coz the tv in there buzzes. When it is on, my digital channels upstairs are fab, when it's off, they pixilate and disappear!!! Try just getting a booster box thing, which just plugs into your main house aerial inlet? Do you live in an edgey area of the Oxford 'mast' too? Best wishes, Caz.x
