Thanks , i would have a few questions first ;
What is connected to this tv ?
Cable converter box,dvd,games etc. ?
Did you have that problem since day one on this tv or this happened lately ?
Customer: replied 1 year ago.
Day 1 was fine, 4 weeks later the issue started. Only have a Foxtel cable box attached for all content input. Nothing changed since day 1 setup.
Suspect Android OS update which happened last week.??

O.k then very often the cable box will have a function/option to sync video and sound and so should your tv but sony Australia seem to hide their manuals pretty deep , (still looking for it) .

Not sure if the foxtel boxes are the same as north American cable boxes but I can tell you that it is common here with cable boxes and usually a reboot will do the trick.

Try this ;

Pull the cable box`s power cord off the wall outlet (cable box only) for a minute.
In the mean time turn off the tv and turn it back on only after you plug back the cable box power cord.
Note that it may take a couple of minutes for the cable box to reboot after you plug it back ,just give it time.

See if that helps

O.k then , was waiting for your reply and I can tell you that so far nothing in your TV's manual seem to deal with that problem but from experience you won`t need that anyway , the reboot will do it
