Thanks for all the advice, I’ve tried everything recommended ,bought new HDMI lead and had TV aerial lead and connection lead from Humax to TV made up., that was £28.Re routed HDMI away from aerial leads, Hasn’t worked, removed the channels giving trouble from TV.
Removed Channels
Sony Movies
ITV 3+1
Channel 5+1
Sony Movies Action
Film4+1
ITV 4 +1
Horror Channel
There are others all around the higher number channels before HD starts
I have given up now. I won’t miss most of these channels, but the earache from her indoors and family has made my decesion to ditch the Humax and try something else.
