Digital tv signal poor on youview box

I have had BT tv now for just over a month, from day 1 the digital tv channels have all been suffering from low tv signal. All multicast Internet channels and on demand works flawless and the only issue I'm having with the box is freeview channels becoming pixilated and jittery over and over. The maximum signal strength the box seems to get is 36% but if I plug the aerial into my tv's built in freeview then it happily sits at 94%, the same goes for signal on other tv's in my house using freeview.

 

So far I have done the following:

 

Reset the youview box

Re-tuned the freeview channels over and over

Had a professional check the aerial (This is when I had all tv's tested in the house for signal quality, along with adjustments to the ariel which did increase the signal strength from what it originally was, this did not change anything on the youview box)

Changed the tv aerial wire

 

Does anyone have any suggestions on what else I can try? Or does it sound like a faulty box.

 

Thanks in advance for any help.

Re: Digital tv signal poor on youview box

ensure that the cable coming from the aerial goes to the youview box first. then daisy chain any other devices after.

Ensure the aerial plug is a tight fit on the YV box, get signal strength up on the screen then wiggle the plug, see if strength changes at all.

Re: Digital tv signal poor on youview box

I have done all of the above without any change in signal quality. I have also changed the tv aerial cable again to one that seems to fit into the youview box much tighter and there is still no change. I have also just as a test routed the tv aerial through the sky box then into the youview box and the signal is exactly the same as to when its directly connected. The tv aerial signal is still reading >90% on every other tv in the house. I can only assume at this point the box is faulty

 

How do I go about escalating this to someone from BT that does not read a script off the telephone? The call centre people over the telephone just keep giving me the same "fix" and then try to tell me its my internet connection when digital tv channels are nothing to do with internet connection, all the iptv channels work falwless.

Have you turned on RF Pass-through in the Youview box settings?

 

An alternative it use a passive or active RF splitter to feed the Youview box and TV separately (which is what I do).

Still exactly the same issue remains no matter what I do.

Re: Digital tv signal poor on youview box

I was having a similar problem with pixelation and break up of freeview channels.  Like you I found that I was getting a higher signal on the TV than I was getting on the YouView box.  When your aerial was checked did they check for interference from 4g?  This was my problem which was fixed by fitting a filter on the aerial lead.

Re: Digital tv signal poor on youview box

Not sure about the 4g interferences check, how do I go about this myself or is it going to need a specialist to do that?

 

I have also today tested the youview box in my garage by using the main cable coming into the house directly from the TV aerial and the signal is exactly the same. I also find it strange how the signal doesn't even go up or down during bad weather (Noted yesterday) where as on my other tv's during bad weather the signal will be moving between 85 and 95%.
