I have recently purchased a Sony Bravia X90F. I have scanned for channels and now have several to delete or hide. I have followed the instructions on Tom's Guide on how to do this but the Hide/Edit option does not appear on my screen. I have Googled for instructions on how to do it but none of them mirror what is displayed on my screen. I know this should be simple but for the life of me I cannot work out how to do it. Help!!
