Picture and sound breaking up (pixellation) on certain channels
Hi for the past few weeks we have had major sound and picture distortion (pixellation) on certain channels, mainly HD ones and particularly sport and cinema channels and on channel 5. We have tried changing the hdmi lead, hdmi port, tried swapping the box with the one from our bedroom which does the same, have rebooted the box a few different times, have tried running the test from online but it doesnt work just get an error page.
Cant get to speak to anyone on the phone obviously due to corona at the moment, is there anyone on here who can help? There is no problem when watching something from catch up, on demand etc or on any apps used like netflix, its solely on live tv.
