My TV/Sound system has never worked together properly to the point that it reminds me of the old karate movies with the delayed dialogue. When contacting customer service, the response was programmed but insufficient to determine any solution.
Most importantly is the continuous problem with my Samsung Refrigerator icing up where it shouldn't and the icemaker jamming up because it was icing over. Also, my oven's performance (i use that term, loosely) went rapidly downhill with the top cracking and a burner lacking temperature control (automatically set on HIGH).
Though I am still putting up with my TV/soundbar, I replaced these two substandard appliances. This is why I am advising people not to buy Samsung.
