On switching on my KD48A9 OLED TV last night, it was completely silent. Picture perfectly good as usual. I could do nothing to solve it. I tried various tweaks to the settings in the Sound category. Nothing. The TV was purchased in the last quarter of October and I was in despair. Finding nothing on screen to help I went to the Sony site on my PC, where I spotted advice to reboot the TV: you turn it off, then point the remote at the screen LED at very close range and keep the remote button pressed for about 5 Secs. Bingo, sound returned. I still have sound, but no certainty that this won't happen again...and again...and again. What caused the sound to fail? Worrying. Am I alone?
