Hello Guys. I recently bought a Q6FN as well and the First thing I noticed was the popping/cracking noise. I immediately took it back to the store where I bought it from. The shop owner told me that the specific Samsung TV models (Q6,Q7,Q9, 55-65-75NU etc) are faulty. These sounds are not normal and Samsung tries to sell these TV to get rid of them. In my country, all these models have a discount prize. Never buying from Samsung again.
