Thanks. Apparently there's an upgrade I can do with Vodafone for even faster cable, plus a router with two Wi-Fi bands so I can move up from the 2.4 to 5 GHz and I think the install is free so I'm planning on ringing them tomorrow. It would be good to no longer have Wi-Fi interference with my wireless headphones which are on 2.4.

As an addendum, I checked the specs for the PVR and although I couldn't find the information I was looking for, I strongly suspect it uses a 2.4GHz processor which would explain things.

Today I've ordered a Fibre-X upgrade from Vodafone; it is twice the speed and half the cost (for the first 6 months in any case, then still $30 bucks cheaper than my current plan) and includes a new router with the 5GHz Wi-Fi option. It's win win.

FWIW I've been having this problem in Auckland (St Lukes) since around the time this thread started. Unfortunately Im in an apartment complex and the property manager says no one has reported the same issue, and I can't access the roof if I wanted to have a look myself.

I have a 2011 Panasonic Viera tv with built in freeview tuner and was wondering it's possible the tuner board can deteriorate?

I have pixelation across all channels nearly constantly, with some channels only slightly better (Al Jazeera) than others.

I have tried unplugging/unplugging the cable, and re-tuning and fine tuning the channels. With the signal condition overlay on screen, I can see the signal condition fluctuates alot especially on tv1, 2, 3.

In your situation the best and most logical step is to take your Panasonic to a friend and try it there. This immediately eliminates all other possibilities. Next best, depending on your location, is to rig a temporary aerial indoors to see what that does. Other people have suggested interference as a cause of this, and if you are in an apartment that certainly could be a possibility. The only other thing is that your own connection to the rooftop aerial has a problem.

Have you tried a different cable between the wall socket and the TV? Some of those shorter cables can be rubbish. I had a brand new one once that wouldn't work at all.

UGH. Long story short, I believe it was my Chromecast causing the issue, but not because of the wifi but because the power cord for it takes power from a USB port on the side of my TV, and that cord was in close proximity to the TV aerial. Moving it about 6 inches away from the aerial made the problem go away.

It is still happily connected via 2.4Ghz and pixelation of the TV signal has now disappeared.

That may also indicate that the Antenna cable from the TV to the Wall Socket is of poor quality.

If you have the old VHF aerial up maybe that is creating some interference, it did in my case, just disconnect it and see. If not, as you were!
