I got a new UHD TV recently and upgraded my Sky account to include the HD ticket.
We are now getting an odd problem which comes and goes. Sometimes, TV1, TV2, TV3, Prime and Soho are all blank. All of the Sky Sports HD channels are broadcasting fine. All the other channels in SD are also fine.
If we try and watch a recording from one of the missing channels, we get the same blank screen.
We shut the box down and leave it overnight and then it is fine - all channels work and the recorded show that we could not see previously is fine.
A Sky technician visited today - when it was working fine (of course). He gave us a new decoder.
A box reset means the channel returns briefly. So, if I reset it, TV1 reappears until I change the channel and then it is gone again.
Problem has returned tonight. Can't be the box because it's new. Could be something on the TV but I can't find it - any ideas?
If I can't find a solution, I suppose I could record a video of the problem and send it to Sky so they can see what I mean.
