many thanks!
could you give me the link from which you took the screenshot?
It's from service manual for Samsung smart tv. You can find some of them here on forum. Use search box.
TV remote arrived, I changed BOM, Type and software in extended menu
Download service manual for your tv and check there for more info. Maybe some parts aren't compatible or need some adjustment. For now I'm out of ideas what you could try more.
Change "Type" according to service mnaual it should be 48A1UU7WJ or check panel "type" on label on LCD panel and you have there 55A1UU8XJ
