Costco has a great return policy if it comes down to that,but I'm not sure I would mention to Costco or Samsung that you shifted the tv and THEN noticed the problem. Second suggestion,plug in some headphones or external speakers...does the sound change? Third,hook up a dvd player if possible...does the sound change? All these should help determine if it's internal speakers,the signal from the basic cable, or a bigger issue. Good luck
Two month old TV purchased from Costco. It has been functioning wonderfully before it was shifted to sit on a new stand. The audio goes into a warped mode and sound very garbled. Gets corrected after a few seconds before appearing again. The same has been observed on more than one channel. I have the basic cable, which is plugged directly to the TV.
Will a firmware update help fix the issue? or I would have to call Samsung?
Any help appreciated.
