Have recently bought the new QLED75T 2020 tv and am having constant issues with the sound suddenly shooting up for around 30 seconds then reverting back down to normal level set. I have seen a few answers on internet such as auto volume and using ppm.
I have the auto volume set to no now and PPM selected but this has not resolved my issues?
TV is 3 weeks old, was hoping it would settle down but this has not happened.
Any advice or should I return to the store for a refund
