I have had a Samsung Smart TV a couple of years ago and have been pleased with it until recently when the default source has become Rakuten TV running ads for films it offers. I tried moving it on the source bar at the bottom but still it was the default. I tired deleting from the source bar and the menus (you can't) but after an internet search (https://www.cb-net.co.uk/general-tec...ung-smart-tvs/) I found that deleting channels 4000, 4001, 4002 etc. removes it, which I did . But I was far too pleased with myself too early. A few days later it appeared again. but is no longer in the channel lists so cannot be deleted.

Does anyone else get this annoying piece of *&^% and has found away to successfully remove it permanently?
