I have just added a Samsung HW-T420 soundbar to my Samsung TV after using an LG surround system. The soundbar keeps losing sync with the TV. If I power off the soundbar and turn it back on it corrects itself, but then after about an hour switched on it starts to lose sync again and it needs to be powered back off again. The connection between the two is with an optical cable. I never had a problem with the LG system, the fault is definately with the soundbar. Any advice on how to fix this?
Thanks for that, but that isn't the problem. It is in sync when switched on, it just drifts out of sync the longer it is switched on. If I adjust it to match using that method , within a few minutes it drifts out of sync again.
