Whilst the pixelation was occurring (on two different V6 boxes at the same time), I checked the tuner signal levels by selecting the following option in the menu;
HELP & SETTINGS
Both boxes were showing the following;
Two of the 5 tuners showed signal levels of 69% whilst the other three showed 100%, as they normally do. This was happening on two different V6 boxes, at the same time, fed by 2 separate cables from the box outside my house.
When the pixelation had stopped I checked the levels again, ALL 5 TUNERS IN BOTH V6 BOXES then showed signal levels of 100%
(SNR of 41 dB and AGC signal level of 0%)
This surely proves that it has nothing whatsoever to do with what resolution that you’ve chosen, what cables you use, or how many times you’ve retightened your cables and rebooted your box?
What is does prove is, that at certain times, on certain frequencies, the signal quality transmitted to our house varies. This surely is, (as the Virginmedia Engineer told me) a network problem that Virginmedia are we’ll aware of.
For the last 2 months, we have struggled with frequent pixallation issues. We have 2 v6 boxes. Lounge and bedroom. Happens on both. Mostly bbc, itv channels and channel 4 but happens on all channels. I have tried to reboot the boxes but the issues remain! I have not changed anything, cables etc since installation which was less than 2 years ago
I'm really sorry to hear that you're having issues with your TV service and it does sound too coincidental to be happening on more than one box. I would like to look into this further on your behalf. Please look out for the purple envelope in the top right of your screen.
Sorry to hear of the pixelation issue. Is it on both boxes or just one? Looking into this, one of the boxes is fine, however the other box is not turned on so we'll need to have that one on to run tests 🙂
