Hello! I have a huge problem.... after latest update to 1420.09 firmware my TV sound connection is a pure mess. Not only that Adaptive Sound+ feature stopped working in Game Mode. Now if i go back to TV menu and get back to PC input and press sound mode change button on my soundbar remote, the TV keeps constantly scrolling through all sound modes infinitely. I can't roll back to previous firmware, what can i do now? TV is unusable
