Hi all, I am having huge problems with my new TV connected to my Sky Q 2TB Box.

All starts off okay but gradually the sound begins to lag behind the picture until it breaks up and sounds like Mikey Mouse.

If I turn the TV off and on again it will be okay for another 5 minutes or so ... repeat but the symptoms are the same.

I have tried all HDMI ports and tried different HDMI cables.

Have set Sky and the individual HDMI port to the same settings but no difference.

Any help would be so much appreciated.

Many thanks ...

p.s. works fine with my old TV
