Yes I have unplugged it all and restarted. We have only had the tv a few weeks and noticed the problem from the start. Model no. UE32EH4003.
There is no audio delay option in the sound menu. Is there anywhere else I can change these settings?
Menu/sound/additional settings. Additional settings isn't available (greyed out). You can view the options in additional settings but the only options are DTV Audio level and Dolby Digital comp.
Yes, I have a USB drive to hand.
