TV interference

Ian19571 — Thu, 14 Aug 2025 18:49:32 GMT

I have a Sky HD+ box connected via HDMI cable to an LG Smart TV. The sound quality is excellent but the picture is being interfered with by lots of horizontal lines across the whole screen that are random in position and intensity. I've checked all of the cables, connections and dish and all seem to be intact with no loose connections. I have shut down all other electrical equipment in the house but that hasn't helped. For reference I live in the Halfway area of the Isle of Sheppey, Kent. The date I am writing this is the 14th August 2025 and the problem only started 2 days ago on the 12th. Any advice would be greatly appreciated.

What are your Signal Strengths/Qualities? Take a look at the link below:

See question Q11 in my Sky Plus F⋅A⋅Q for Signal Strengths/Qualities

Both signal strengths and quality are good.

Personally I'd suspect a TV issue and try another TV attached to the Sky box

Thanks Annie+UK. My wife doesn't look impressed that we may have to buy another TV. Very greatful for your help.

@Ian19571 if your TV has a second HDMI socket, you could try swapping the connection to that. Also try a replacement HDMI cable.
