I came across sound issue on this particular TV.. Depending on how loud and what are the noise frequencies, the back of TV rattles alot. Tried to put screws into sockets that are ment for wallmount, doesnt help. Is there an option to play with equalizer to reduce bass of speakers. Its a little crazy for TV that costs that much and rattles like an old lamp TV with missing bolts. Later i will mount to wall and that would fix the issue but intil then would have to adjust sound settings, tried to play with options and look for answers and cant find. Already tested other TV same model as i have, seems like the back rattles on all of them. Suprisingly havent seen threads regarding that.
