Hi, thanks for your reply. This happens using either live (digital) TV via the antenna or the satellite via the dish, no set top box in use, only the TV.
Yes when I hit select there are toggle type choices for language choice and subtitles (i.e. closed captions I presume) etc. I can toggle them between available langages or Off. This works fine.
BUT I have to do this EVERY time I change channels. Yikes! And also when I turn on the TV - the captions appear to be always ON by default.
I think I have been over all the options since this TV arrived for Christmas, but I'm still hoping there may be a solution. I also did a reset/initialise to the whole setup and this led me to realise it was just changing the language (sound) that automtically turns on captions. Which is crazy in my opinion 😉
