I just picked up a 75 inch qn800a. Picture looks great but on certain frequencies the rear of the tv rattles like a blown speaker. If you touch the back lower part of the tv while it’s vibrating it stops. Is there anyone else out there experiencing the same problem? The tv is only 3 days old . Thanks for any help or fixes .
Mine was doing the same exact thing. So I went behind it and held a speaker and it stopped. Then I noticed one cable was lightly touching one of the speakers. I moved the cable away from the speakers and it sounds great now. The slightest thing touching the speaker will cause this problem.
