I have an LGOLED55C8PLA connected via a sonos beam gen 1 but lately when watching football on my iptv box I see a red band about 3ins from the bottom of the tv screen that goes across the whole screen. This does not happen when watching my TV through an aerial but I tried it with both my boxes and both had the same issue. I guess its some sort of wiring issue but not sure how to resolve this issue.
Any help or advice please?
