BT Vision box signal strength indicator

Just received the latest black BT Vision box replacing an older version. Old version worked really well, good picture. New one using same leads and aerial point pixellates at times horribly. The signal quality indicator usually indicates 100% and is green in colour. The signal strength indicator varies: sometimes is shows over 70dBuV and is red, other times it is around 64dBuV and is orange and occasionally it is around 56dBuV an is green. What should it be? It pixellates even when the indicator is green. I had a big new roof aerial fitted a few years ago and there is a booster/distributor box in the roof - currently running just two tv's off it, although rarely at the same time.
Why does the new box not work when the old one did? What do I need to do to cure this? Is the signal too strong or too weak?! Any ideas out there?
Thanks, Graham

Thanks for the feedback. I have tried splitting the aerial with a passive splitter - perhaps marginally better but difficult to say. Even tried splitting again to the point where the signal was showing weak. The strength indicator seems to have a colour coding, starting off red with a weak signal, going orange, then green, then as the signal is stronger it goes orange again and back to red when too strong. I have hit the green optimum region and gone either side of it. Pixellation is always there. Reading all the posts on here about this, I am coming to the conclusion that I am not going to be able to fix this.
I may ask BT to reinstate the old box, it worked perfectly - I only asked for a replacement so that I can have BT Sports and the option of Sky sports. I will just have to stream BT sport to my laptop if I want it. I am a little disappointed about this though.

Ignoring the signal strength indicator.....

I see a lot of posts saying they have less bars on 3G... etc
My question is for Gen 1 owners who now have a gen2 phone. WIthout comparing the signal strength indicator do you find reception is better, worse or the same...
Also, is the sound quality of the speaker better as they claim?
Thanks

I didn't have a first gen iphone but I find reception much much better, in areas where there were dead spots I have great reception...even in my house...which is the opposite of what I heard about 3g...now I just need my phone to receive calls and voicemail...my port is taking forever since 11:15AM yesterday...its now 8:08AM my time and no dice...

Signal strength finder via black bt vision box

I have recently changed from sky (could be a big mistake) and have had constant troubles ever since.
The latest is I am getting pixelation on all tv channels.
Looking at the online "help" I have checked the aerial connections (all good), Aerial (brand new £50) and pointed in the correct direction. The next item was to use the handy signal strength checker as per BT's instructions.
However these do not appear to match what appears on screen.
You can check your Freeview signal using your Vision+ box, but please be aware that checking your signal will interrupt any recordings that are in progress. You only need to check the signal of one channel in a multiplex to know what signal you'll be getting for the whole multiplex.
How to check your signal:
Press the BT Vision button on your remote control.
DID THIS
Scroll across to Settings.
SCROLL ACROSS GOES TO TV SO I SCROLLED DOWN.
NO "SETTINGS" PAGE SO WENT TO "HELP & SETTINGS"
Select TV Settings.
DID THIS
Select the DTT Signal Strength page.
NO "DTT SIGNAL STRENGTH" PAGE THE ONLY OPTIONS ARE 1/sCAN FOR CHANNELS, 2/ CHANNEL MANAGEMENT, 3/ TV SHAPE.
The minimum signal strength and quality you need for a good picture is:
Signal Strength - 55%
Signal Quality -70%
Am I going mad ?
Can anyone help please?
Solved!
Go to Solution.

There is good news and bad news. The good news is that you are not going mad. The bad news is that you have a new version of the software which unfortunately doesn't include a signal strength tool.
Does your TV have a Freeview tuner? If so, try using signal strength on that.
Your signal could be too weak or too strong. If it's too weak you may be able to use a booster. If it's too strong you can use an attenuator.

Checking signal strength with cable box on

If possible, how would I be able to check the signal strength for one of my cable boxes while it is turned on? I know how to do it when it is off and I know how to do it with a digital adapter. I asked a whole back specifically regarding the Cisco RNG150N but I didn't get a response.

If it's a non-x1 RNG150, then I do not believe there is a way to do it with it turned on. Is there a reason why you don't want to turn the cable box off?

Dying box or bad signal strength?

I have an older model grey HD DVR box that I have had for a few years now. I live in a highrise condo. Over the years there have been issues with a channel here and there going out. When I go through all the troubleshooting, etc the problem does not resolve. The only thing that ever worked was having a tech come out to the building and boosting my signal strength somehow from the utility closet. Or there have been issues where new installs in the building have messed up my service. Last week I started having the same sort of issue so I called Verizon. The guy on the phone believed that signal strength was not the issue, but rather than I needed a new box. I am skeptical this will solve the problem. But the issue continued to get worse over the last couple of days with more and more channels going out to the point where I am down to about 4 watchable chanels. The new box should be here today so I guess I will know tonight. When I do the diagnostics the box says the network signal is either weak or not there. The guy I spoke to on the phone had me enter a special menu which gave a strenght of about 26 but said "poor". He claimed anything above 25 was acceptable. So I don't know why the box deemed that to be poor. Last night I did the regular system check using the "menu" button and the OOB was about 24.
Hopefully the new box is a new model. It would be nice to upgrade from the old equipment. But after reading all the problems here maybe that's not what I really want. :-)

I'd be more inclined to check for bad connections than to suspect the box. You don't indicate if you have an splitters installed, or if the box is directly connected to the wall outlet. If you've got splitters, start there -- remove them and work your way back to the shortest possible run with no splitters and see what your signal strength looks like.
Also, do you have other outlets in the house which are connected but not in use? Those can introduce noise into the system which if you have a weaker signal can cause you issues. Put a terminator on them if you can't have them removed entirely by taking out any splitter which supplies the signal to that outlet. I have one box which is at the far end of 4 splits (the splitters themselves account for 12 db of signal loss plus the long run takes out several db more) and occasionally I have a block of aout 4 channels (all running near the upper end of the frequency spectrum near 800mhz) that go out (these are the HD signals, the regular SD version of the channel stays operational). When this happens, I go around and disconnect/connect all the connections at the splitters and wall outlets and that usually does the trick. My boxes with stronger signals aren't affected by the dropouts -- so the poorer your signal, the more likely to have that kind of problem. I've had stuff work down into the -30's without issue.
However, never hurts to replace the box if Verizon is willing to send you one. That just eliminates one of the possibilities and if it doesn't work allows you to focus on something else as the cause.

New Black BT Vision box - what is missing, a discu...

Maybe it's just me but here is a list of things which are currently missing or wrong with the new BT Vision box (black edition with new interface and OS). Thought it might be useful to keep a list of these going which people can add to.
would also appreciate it if anyone can help with any of these issues in case i've missed something
Red button doesn't work - believe this is 'coming soon'. you can still access the channels by going to 301 or 302
Teletext doesn't work - the button pops up a message saying it's not available, coming soon?
There is no way to set recordings to over run? - this used to be very handy on old box, particularly with live shows. is this being brought back?
No signal strength tester - you used to be able to check digital signal reception strength and quality from the settings menu, not any more
Pressing 'play' when viewing a recording doesn't flash up the progress bar - any other good way to do this, used to be handy. Fix: pressing "select" does the trick
no HD Freeview - the box isn't capable, wondering whether they might upgrade us to YouView later on for this?
No options to set resolution - used to be able to define 720p or 1080i for instance, not any more
Sky Sports small white box - a small logo in the bottom right area, not sure what this is or why it's now there?
Subtitles on iPlayer missing
Some reported picture quality issues - both on SCART and HDMI
On the plus side:
Bigger capacity on the hard disc
Faster inteface and movement between sections
Nice new design and sharp interface resolution
Channel logos / graphics now in the information bar menu
When in the TV Guide there's still a small box showing you what you are watching on the current channel
Music playlist
Bookmarks
Reinstatement of the 30s jump and better fast-forward / rewind (30s jump doesn't work on Sky Sports)
Ability to jump to specific point in recordings (you need to start it first, then stop and go back into it to have option)
Ability to reenter a recording at a time offset
Icon to show which recordings have been watched
HD iPlayer
Recently viewed in iPlayer
Ability to resume a programme on iPlayer
Ability to resume on demand
Disk usage on Recordings page
Auto switching format for HDMI and SCARTOne-press toggling of Subtitles and Audio
Previous channel facility
'Play all' feature for On Demand series
anything else people want to add?

New replacement (black) BT Vision box

New black vision box arrived today, installed, but trouble. Most channels are not available and others have distorted sound and picture. ITV1 is OK cannot get BB1 and many others. The Vision box is connected direct to the TV, no other device inbetween. Switched off scanned again. Same result. BT India say I have a signal problem which is not their problem. I had no such problem with the silver box. BT India say I cannot reuse it as it has been deactivated. I am sorry I laid eyes on the black box which I did not want anyway. Any advice please?
Solved!
Go to Solution.

Does the menu run along top or left hand side.
If left you are on the new OS and will not be able to check signal strength, sadly.

Problems with signal strength with channels on Mux...

I've had a YouView box (Humax first gen model) for almost a week and i'm having pixelation/signal strength problems with all channels on Mux. Com5, Pick, Dave, Movie Mix and Really etc. My Vision+ box and TV are showing these channels without any problems. Any ideas?

I have a similar problem.
(But not on Crystal Palace Tx).
Switch to a poor channel. (Dave for example. This is one I have problems with).
Go to Settings, TV Settings, Freeview Signal Strength.
Now press the Info button to get extra information.
Note the UHF channel number, the channel is being received on.
Get the same channel information, on the other Freeview receiver you have.
In my case, the UHF channels are different.
I believe, the Youview box is pre-set to receive from a transmitter (and hence a UHF channel number), determined by a post-code and/or your address details.
Because my aerial is not pointing at the main transmitter for my post code, I get poor reception because the transmitter the aerial is pointing at, transmits Dave (MUX) on another UHF channel.
As confirmed by the other freeview receivers I have.
There doesn't seem to be a way to force the box to use any other UHF channel.
Any scan always comes up with the same one.
There is no manual setting.
I might be totally wrong, but I think this is another software bug.

Iphone in Great Britian discovers Apple tech problem - Signal Strength -

November 25, 2007
Signal trouble: British iPhone mystery
Is O2’s network to blame, or Apple’s (AAPL) iPhone?
That’s the question posed by more than a few British iPhone owners who purchased the device in the past two weeks and have been struggling ever since to get decent telephone reception on it.
The problem surfaced two days after the phone went on sale in the U.K. when “Matlock” in Derbyshire started a discussion thread on Apple’s support board entitled “UK 02 (poor signal strength/reception problems)”:
My iphone can barely pick up even the slightest signal, although on occasion can pick up 3 ars, only for it to drop out again. I have two other 02 phones, a Sony Erricson and a Nokia n95 with no reception problems at all. Is anyone experiencing same problem with their iphone, I would like to hear from you. (link)
Two weeks later, Matlock’s query has received more than 100 replies (and 3,723 pageviews), most of them registering similar complaints. Some users found that reinstalling the software made a difference. When others returned their phones for new ones, the problem went away (although some reported that the new phones were no better).
Definitive U.K. sales figures are not available, but O2 reported that it sold “tens of thousands” of iPhones the first weekend it was available.
Several posters on the Apple discussion board volunteered that unlike the complainants, they were getting great reception on their iPhones. And many owners with signal problems expressed pleasure with how well the device performed its other functions.
But unlike American iPhone owners, who tend to blame any reception headaches on AT&T’s (T) cellular network, the assumption in the U.K. seems to be that the signal problem is Apple’s. The impression is reinforced by O2, which has been referring callers directly to the manufacturer.
One clue is that many British iPhone owners can, like Matlock, compare the signal strength on their iPhone with other cellphones using the same network (one user even posted photos showing the phones side by side). Another is that the indicator on the iPhone tends to jump to five bars as soon as it is placed in the charging dock, which suggests that the problem is battery related. As user Richard Catledge points out:
It says in the manual that phone signal is adjusted to the minimum power when not in use, just enough to detect the incoming pings, then it will power up to get the best quality call. It is digital, so as long as the signal power is strong enough to reconstruct at the other end, more power is pointless. I suspect this is what you are seeing, or a slightly flakey implementation.
Meanwhile, the consensus on the discussion board is that unhappy owners should let Apple know. Writes one user who posts as ::…SAM…::,
The only way to get anything done about it is if people that have poor signal problems is to take your phone back and get it replaced. The more phones they get back, the sooner they will do something to fix the problem. Emails and complaints are fine, they can be put in a folder, high handset return numbers cant be so easy to hide under the rug.
Thanks to InformationWeek’s Alexander Wolfe for the link. See his report here.

Interesting post. My previous phone was an 02 XDA Exec, a smart phone based upon a common handset (forget which one), but the smart phone before that was the same. They all had one thing in common - poor reception.
tbh, I think its an inherent problem with smart phones. However, with my iPhone I haven't noticed anything out of the ordinary really. Its better than the XDA, at least the iPhone doesn't drop out completely!
But compare it to a normal handset and the normal handset will normally have a much better reception strength.

Bt vision box wont let me watch any channels while...

bt vision box while recordin 1 programme i go to another channel to watch it says no signal or weak signal, and the rest of the channels say the same thing. we have recently brought a new areil lead which is shielded,we stayed on a channel wid the blank screen and when the recordin finished the picture came up we have had problems before this its very annoyin all we do is try and fix this problems any1 know what could be wrong.

no signal or weak signal normally mean an aerial problem or you are in a poor reception area at the moment till the digital switch-over is completed in your area

BT Vision Box unable to show Freeview HD channels ...

I have been sent a BT vision box due to the fact my Youview Box is unable to have the skysports channels I was told this was a newer box I was told on the phone and my youview box was outdated when I suscribed to the Skyports channels just last week. I plug in my BT vision box everything is fine except I am unable to watch Freeview HD channels.
The Problem is my BT Vision Box shows the Sport Channels except the freeview HD Channels, I get them on normal.
My Youview box shows the Freeview HD Channels and everything else expect the Sky sports channels.
I have spent 2 hours on the phone last week with the technical support team and probably even more as I called twice they even put me through to the sales team because I said I wasnt suscribed to freeview channels (because thats what it says on the TV) and everyone was telling me I was suscribed and I was unable to view the Freeview HD channels. I even took a day off work which I will not get back to get a freeview engineer guy to come to my house which the BT technical team sent and tell me theres nothing he can do and he checked my signal and said it was perfect and told me the Youview box was newer and the BT vision box was older even though I was told vice versa by a BT sales rep when I bought the Skysports channels.
So can someone help me so I can view all my channels I have and not have to swap between boxes and I do not want to speak people on the other side of the world to sort my problem out.
I have done the search channel and reset the box which has not worked.

Utter nonsense! The black BT Vision+ box came out at least 3.5 years ago. The BT Youview box came out just over 1 year ago.
The reason you can't have Sky Sports over Infinity on the BT Youview box is because Sky haven't agreed to let BT resell Sky Sports on that platform. It's not due to any technical limitation. BT have asked Ofcom to look into this.
The reason you can't pick up the Freeview HD channels over the aerial using the BT Vision+ box is because it is a much older box and doesn't have Freeview HD (DVB-T2) tuners. You need to pick them up over Infinity by getting the 'PSB HD' multicast entitlement added to your account.
The person on the phone was talking rubbish. The engineer was talking sense. His trip to your house sounds like a total waste of both your time and his time. At least BT paid for it I assume.

BT Vision Box Not Receiving ITV or CH4?

Hello. I've joined this forum for the purposes of attempting to resolve a problem that my parents are having with their BT Vision Box.
They are very happy with the system in general, but recently my mother has been unable to watch/record ITV very often. She has tried re-scanning for channels, but this simply lost several channels from the tv guide altogether.
Now I realise that atmospherics sometimes play havoc with freeview, but the reason I am perplexed is that my Panasonic tv upstairs (with inbuilt digital reciever) has almost no trouble recieving these channels, bar the odd blip or two.
Yesterday was case in point when I could watch Doc Martin in perfect quality, and downstairs could see literally nothing. Progarm unavailiable. Channel 4 was the same, though it was at least a static broken image on the BT Vision Box, and not just a black screen.
We had a digital ariel installed about 6 years ago (at some cost) which both our televisions run off (theirs through the Vision Box, as their tv does not have built-in digital tuner). The cableing is up to date aswell, and we have some kind of booster attachment aswell (though the guy who installed the ariel insisted it wasn't a booster, but we need it plugged in to get a signal).
So in conclusion, why can't the BT Vision Box recieve channels from the same ariel as my television, that has no problem getting them?

I think someone conned you somewhere along the line.
It sounds very much like a booster to me.
Also the wind ought to have no effect on your aeriel. (note not ariel that's for your washing machine )
It really does sound like an aerial issue to be honest and maybe it would be worth getting someone to look at it.
If you take the downlead out of this box can you plug the aerial in to the TV?
Hang on - is your TV fed from this box?

New BT Vision Box stops my other digital freeview ...

I'm a new BT vision customer and have set my vision box up to include using the poweline adapters as my tv is otherside of the room to my homehub and all works fine.
However the TV we have in the bedroom that has freeview built in will no longer receive any signal. This TV connects direct into a aerial socket on the wall and there have been no issues. For info this TV backs onto the wall where the homehub and one of the power line adapters are.
Any ideas how to get around the issue of all my BT vision kit from preventing the other TV receiving a signal.
TV has been checked and all is ok. Had a scan through google and can see that there maybe issues with BT vision affecting Wii's and so on but not other TV's with freeview built in.
Any help would be welcome.
Thanks!

Any electrical device generates noise which can be picked up on a cable. Powerlines by their very nature can generate more electrical disturbance than most. You can help minimise the effect by keeping cabling as far away as possible from powerlines and transformers. Screened aerial cable may also help with induced noise.
I suppose the cheap and nasty test to see of the Powerline is the cause of the issue would be to temporarily unplug the one close to your upstairs TV and see if the Freeview reception returns. Unfortunately with aerial cables which are buried in the wall you have no way of knowing how close they run to the ringmain, so it's possible that the extra signal the Powerline is putting on the mains cabling could be the issue. That would be a git to resolve.

Is BT Vision Box only able to connect into TV via ...

planning on buying a posh new TV and they seem to have less scart leads connectors. Wondered if the BT Vision box comes with a different way to connect into TV or if it is scart only. thanks im retty stupid i know!

Component is used for devices which send video signals whose components are split into Y, Pb/Cb, and Pr/Cr parts. If you want to read further, then Google "component video". You do need an understanding of colour TV theory!
If a device uses component video, then a separate sound input is needed on the TV. This usually appears on RCA connectors.
Component video, if a device supports its, gives a much better picture than SCART, and is almost as good as HDMI.
Some DVD and media players have component outputs.

New BT Vision Box delivered out of the blue

I have had a brand new black BT Vision Box delivered this morning out of the blue(I currently have on of the old silver boxes). The letter indicated that they were issueing everyone with a new box due to features being rolled out and that the silver box will stop working in 28 days. I have an almost full hard drive of programs and films and there is no way of transfering the data accross. They advise us to watch everything before sending the box back in a prepaid envelope.
As I don't want anything new to be recorded on the old box can I set up my new black box and still watch the recordings on the old box?

Yes you can, but what you would need to do is -
leave the silver box plugged in to the mains and connected to the hub via the ethernet cable
then remove the ethernet cable from the silver box and connect this cable to the black box
switch the black box on and allow it to boot up
The silver box will then run and allow you to watch your recorded content
(putting the silver box in to standby is fine, but don't unplug the mains supply)
