A year and a half ago we purchased a Phillips Smart TV. We now notice that on many programs, NCIS, Chicago Fire/PD, Hell's Kitchen, etc. that there is loud background music which we find very annoying and interferes with the dialogue. We haven't noticed this annoyance before and are wondering if it is the Smart TV. We have tried all the different sound options but to no avail. Has anyone else noticed this annoying background music or any suggestions on how we can fix this?
