The sound and picture are out of sync when screen mirroring from my iPhone 16 Pro to my LGQNED70A6A TV, using the internal speaker. I have tried all the recommended tips in the settings to cure the issue with no success. However, when I isolate the TV from the mains supply for 60 seconds and restart it, the syncing issue is cured but degrades after a day or so. My iPhone software is up to date and there is no firmware upgrade available for the TV. My LinkSys router has a full fibre connection. The only connection into the TV is the mains supply. Any help much appreciated. Thanks in advance.
