Smart Tv

[Spreeny]

When I put my tv onto HD channels, I get (intermittently) flashing lines on the lower section of the screen - does anyone know what’s causing it/ how I can solve this please…. My tv’s an LG
TIA

My guess is that the signal strength isn't as good as it needs to be. (A stronger signal is needed to resolve HD transmission than SD ones. A weak signal can lead to picture break-up).

If you're using a satellite dish, you might need to get its alignment checked, together with its cables and connections.

If you're using Freeview, try one of these

together with one of these (to connect between the booster and your TV set)

i would have though picture break up "pixilating" would be a weak signal fault,not just flashing at the bottom
try what buenchico says though its not that expensive

Are you using the TV internal freeview tuner (if it has that facility) or a separate smart box. Has it always done it? Is the box a new one or a replacement? It doesn't seem to happen with Sky Boxes but there is noreason why it would not. It is a problem that appears to have different solutions for different locations and set ups. It also happens on all makes of TV. It seems to sometimes start after an upgrade and can disappear after a reboot or upgrade. You can also get rid of it by altering the TV resolution to 720 but this defeats the purpose of the 1080p facility. It also seems more common using the less expensive(lower specification) Now tv smart boxes.
