Recently I was getting the weak signal message on the HD channels (101 to 105) through the humax box and now the channels have gone. When I retune I will either find the channels but are black screen (or pixelated) or won't find them at all.
I don't think it's the Ariel on the roof as the ariel wire goes into the humax and from the humax into the tv which is working fine. Also ariel to tv in other rooms via a booster and they are working fine.
Plus my dad also has the same box and is getting the same issue on his tv in a different area
