I've seen some old posts (over a year) via a google search about the issue I'm having which seemed to be a bug then and apparently still is.
I have an OLED55B7V with the latest LG Firmware available according to the Update section on my TV which is 04.70.95.
My issue is that occasionally when I turn on the TV from Standby via the remote, the Freeview channels are no longer tuned and I am required to retune them. I don't experience any issues tuning them and they will stay tuned sometimes for a couple of days.
There doesn't seem to be anyway of reporting the bug. Is anyone else experiencing this issue or know of a way that I can resolve it?
