well, been monitoring this thread and the cnet one for a month, with people trying various things and the reset helping most people at least until they unplug their tv or lose power. the cnet forum has a lot of posts on this.
I have not had any problems for just over a month. but had to uplug the tv over the weekend to move some stuff around.
ROBOT AUDIO RETURNED IMMEDIATELY AFTER PLUGGING BACK IN.
again, i had zero problems for over a month, but after plugging back in, there it was in full fury within the first 5 minutes.
DID A RESET, PROBLEM NOW GONE, AS EXPECTED.
has been fine for 3 days, and expect it to be completely fine until it is unplugged again.
WHY? I HAVE NO IDEA, SAMSUNG, WE ARE WAITING.
