LG 55SM8050PLC (2020)
I added a programme to the favourites list and since then the TV continually flashes between a programme and the 'Live TV' symbol shown in the Home display.
No input from the remote control is accepted, the flashing continues.
Tried turning the power off and restarting, no change.
Turning TV off and on, bo change.
Leaving it off or on, no change.
