I'm sorry to hear that you're experiencing pixelating pictures on your HD channels this last week. I'll be happy to help check this out for you.
I have carried out some checks on your box remotely and signal wise all looks great. Can you let me know if you're still experiencing pixelated pictures and if this happens at random times or specific times of the day?
Also if you wouldn't mind checking that leads are connected and secure in the back of your box and that the box is well ventilated please?
I'm here to help, please keep me posted on how you get on.
