Signal issues and channels missing

Hi,

I have the DTR 4000 box, which in the last few weeks has developed persistent issues with signal strength and quality, as well as channels disappearing entirely.

So far I've tried;

1) Retuning the channels
2) Returning the channels with the aerial cable removed and then retuning again with the cable back in to try and "reset" it
3) The maintenance mode option 2 factory reset
4) Firmware update
5) Retuning again

It's mainly channels like BBC1 and all of the HD which disappear.

Generally when I check signal strength it gives me between 30 and 50% with signal quality between 15 and 30%

As it stands we aren't able to watch a lot of channels, thank god for streaming services eh?

Any ideas on how to solve this would be welcomed.

    Those numbers are awful; SQ should be 100, or nudging it.

    I would suspect aerial failure, or has anyone said “can’t see what this is for” about a little box plugged in the mains somewhere, which is actually feeding DC up an aerial cable to a distribution amp in the loft?

    If you unplug the aerial cable from the YouView box and try it directly on your TV, what then?

    Our trusty aneroid is rocking 1008/756 at the moment. That, and the reappearance of light rain, suggests the high pressure is over, at least in the midlands and southwest.

    Aerial... plug it into the TV and everything works as it should.

    Thankfully we don't have any little box tucked away, it's aerial straight through the wall and into the box/tv.

    Hi Oliverhague,
    If you plug the aerial feed directly to the Tv's own built in tuner, what signal readings do you get? I would also try a unplug/replug & retune of tv channels also. What Roy was mentioning about little box was an aerial amp booster, that does help boost signal. We use several in our home. The problem is that you don't always know where it is fitted, hence it is bypassed or it could even block the signal coming in if found faulty. If in your case there is no little box, my question is has the signal always been this weak?

    Even with transmitter problems, signal should be a lot higher reading than what you are getting. Could be faulty aerial/bad connection with coax cable. One thought, it could also, if a roof aerial fitted, be a simple split from aging in the cable with water entering? How would you know, well simple in some cases to check: a puddle of water in a room near an aerial feed cable. Once we found a puddle of water near tv & thought the dog had done a puddle near the tv(!). The crack in cable was later found. I have now rewired cabling internally to overcome problem.
     Hope you are able to fix your problem. Let the forum know how you get on. John L

    Hi oliverhague,
    How are you getting on with your problem? Have you managed to trace the fault.
    Have a good weekend.

    Hi John,

    Been away for a break so just picked this up.

    Still no luck tracing the fault, although weirdly since we've been back the signal strength has increased and we're able to watch the TV again (mostly).

    We had a brand new aerial fitted 3 years ago and the the cable goes straight from the aerial to the youview box, so no little box and the signal hasn't always been this weak. As I mentioned in my OP, this is a problem which has appeared and then got worse over the course of a few weeks.

    I'm going to keep an eye on it and maybe try an amplifier if it plays up again.

    Cheers
