Normally, one of the first things I would normally suggest it is to check to see if all of the inputs are affected. However if the startup chime doesn't seem to be is clear as it used to be, that probably indicates the problem is inside of the television.
I'm not sure what would cause something like this, however what I would suggest is that you call 800-SAMSUNG and explain the problem to the customer service agent. It may be something simple that a technician can fix, however if the problem is more serious than that, we can have a technician repair the unit for you under warranty.
Please keep me posted.
Hi! We've got a Samsung LED (46", 6000 series) - bought about 3 months ago. Been working fine, but yesterday (after taking it off it's wall mount briefly to fix a non-TV related issue) suddenly the sound has gone muffled/muted. It's as if the speakers are wrapped in layers of cotton wool to the point where you can't really make out what anyone is saying. The starting 'chimes' are muffled, and it doesn't matter whether the source is the TV (through sky box) or through the samsung DVD - so I don't think it's anything to do with the input. I've tried switching the sound settings through standard through all the others, but with only minor differences and certainly no solution to the problem.
Anyone got any idea as to what might have happened, and more importantly how I might solve the problem?
