I have a Panasonic tv model TH 42PZ80B; a Panasinic Blu-Ray dvd model DMP-BD50; a sky box (not as yet HD) and a Sony video SLV-SE 830G. I have a Satellite dish and a normal TV aerial. In the loft I have a...


You need to try and isolate the piece of equipment which is causing the problem.

You've already tried the aerial lead direct to the TV and this is OK.

Disconnect all scart leads and try the RF on its own.

Try the Aerial lead to video, then video to TV.

Try aerial direct to Sky box, then to TV.

Try just connecting the RF out from the Sky box to the TV (no aerial input), can you tune into a good channel 68 picture from the Sky box.

Then Try the VCR to the Sky box (no aerial input), see if you can tune into the VCR and Sky channel.
Hope that helps.......

if you have connected your sky box as per instructions, putting the aerial coax to it and a fly lead(as in a male to female coax as used on a vcr to tv) from the output to the tv's aerial input, then disconnect the aerial from the sky box and put it back to the tv. The skybox will weaken and even loose the signal.

Hi, I have a digital tv plugged into an extension cable in an upstairs (Toshiba) bedroom; it works perfectly - receiving all channels. I have a digital tv downstairs (Samsung) where it seems the wall...


Hi Fiona
Somewhere along the line from the aerial there must be a signal splitter that feeds the upstair and downstair terminals.
Try to find that splitter and switch the output to see if the problem goes from up to downstair.
If it does switch then you know the problem is with the splitter block, and if it stays the same then the problem is with the cable and/or the connectors that run downstairs.
Also the reason you get a pixellated(snowy) picture is because of signal loss during the length of the cable you ran downstair.
If running a cable downstair becomes the best option to fix your problem , then you could buy a cheap 10db signal booster/r.f amplifier to correct the signal loss and a cable splitter to feed both tv`s
That booster would be installed upstair in your case(near the source of the signal to be amplified).
I could send you a small diagram if need be. Hope this will help and Merry Chrismas

Panasonic TX P50V10B Plasma TV


In order to get any of the Freesat channels, you need to connect a Satellite dish to your TV. If you have a Sky dish, you simply need to run an extra Cable from the LNB from the dish and connect to your socket on the back of your TV.
In order to get Freeview channels and Analogue channels, you need to connect a aerial to the back of the TV.
There is a menu option for the TV to start straight to the AV input (your Sky HD box). It is Menu > Setup > Other Settings > Power on Preference. Select 'AV' for your TV to start on Sky HD.
Also even if you have your TV to start on TV, when you turn on your Sky HD box, it should automatically switch to the Sky box.

Tv with built-in digital tuner not receiving any channels


Is your outdoor aerial a proper freeview aerial and are you in a strong or weak signal area.You can check here:http://www.stevelarkins.freeuk.com/freeview_digital_tv.htm
Also check your connections as the coax may be shorting with the braid or a bad connection.once checked try ordinary channels on upstairs tv and if ok retune all your digital channels.
This can be due to a few problems.Firstly make sure your aerial is pointing in the right direction as beam aerials attenuate(disregard) signals which are not pointing directly at the aerial.
make sure you are using good quality 75ohm cable i.e rg6 and connections are good and not shorting out.
The length of run of the cable will also affect the signal as will any splitters or joins in the cable.
If you know the signal is good in your area then it will be down to the aerial,cable terminations ,aerial position or a combination of these.
If the signal is poor you can either...Buy a high db gain arial which will amplify the signal and or a masthead preamp which will again boost the signal.
please note that if your aerial is not pointing in the correct direction then any boosting of a bad signal i.e ghosting...will only make it worse.
try starting from aerial direction then connections then a high gain aerial and or booster.

Technika tv lcd 19-907 tuning in to sky in bedroom.


Hi i had the same problem but i have sorted mine now. What i was doing wrong was i wasnt tuning in the analoge channels only the freeview digital ones. To do this you need to first turn your tv on. Then press the "source" button, this will bring up a little menu at the top left hand side. When this menu comes up press the "Programme +" button (the one that you use for changing channels near the volume button) press this until you get up to "TV", when T.V is highlighted just wait 3 secs and it will switch over. You will probably get a blue screen with a no signal message (you are now on analogue) when you get this blue screen press the "tune" button. It will automatically start tuning in all of your channels, at first they will be fuzzy but as it works they will become clearer. Your sky channel will also be tuned in. When mine tuned in it didnt tune them in on the right numbers though, bbc2 was on number 1 etc. If you ever need to use a playstation or something it goes into the scart connection at the side of the t.v and you need to press "source" and go up to "scart". To get back onto the digital channels just press "dtv/dvd".
hope i helped!

I`ve set up my philips digital terrestrial receiver DTR220 and i`ve scanned for all channels, but i can`t pick up any because my aerial is not picking up any signal. I`ve tried different, stronger aerials...


I actually moved my tele to the other side of the room to see if it would work in a different spot and it took me ages to get some signal by moving my aerial around. The signal still wasn`t strong and i didn`t have alot of the channels and then i turned it on a few weeks after and it was working perfectly. Don`t ask me why! :s

Sky upstairs


Yes on the back of the box there is a RF2 output...

run a coaxil aerial cable from there to your required TV, you then need to tune the 2nd tv to the sky box.

You can also buy a 'Magic Eye' and a 'extra remote' this will allow you to change channels from the second destination with only 1 digi box.

Down point is that you have to watch the same channel on both tv's.

a second card and box and a dual LNB will allow you to watch seperate channels.
