I have been experiencing pixellation for a number of months now. This occurs on live TV and recorded programmes, and appears to be all channels. I've checked connections, changed HDMI cable and reset the TiVo box, but still having issues. It's getting to the stage where I'm having to delete recorded programmes as they are unwatchable.
Thanks for posting and welcome to the community. I am sorry for the TV issues. There is an ongoing SNR issue in your area (signal to noise ratio). The fault number is F008108879. The estimated fix date is 11pm tonight.
