I will never never never never buy a samsung tv in my life because i had this issue in my 50mu7000 2017 model. And now i bought the 55 q60r and this clicking sound drives me crazy and i cant even sleep. All new samsung have this issue, simply samsung is selling us cheap and bad components for some high prices 😠
Costco Concierge (after 4 hours on the phone) finally sent out a technician to replace teh power supply board, the motherboard, and the speakers. The popping/cracking sound is perhaps worse than before.
I don't see any screws to loosen. The technician showed me a custom tool they use to snap off the back of the enclosure.
I've been waiting a week to find out what are the next steps.
