Have you looked to make sure that all of your (BIOS Configuration) settings for CEC actually survived the BIOS Update process? In some cases, depending upon the types of changes that had to occur across these six BIOS updates, settings could be reset/modified.
Thank you. Of course. I've tried to reset BIOS by F9 and set all relevant settings again, too. No success :-(.
I ve the same problem. Only wake on tv isnt working.
