Sound problem Samsung LCD TV A550

by isles81 - 7/9/08 1:42 PM

Ok, I got this TV and it had been great. But, sometimes when I turned it on and it was set to a particular input, but the device that was connected to that input wasn't turned on, I'd hear an awful loud crackling/rumbling sound until I turned the device (i.e. cable box) on. No problem, I got used to turning on the device before the TV.

BUT, last night while watching cable tv, the audio started crackling/rumbling and there was no tv audio anymore. Instead I just had this crackling/rumbling noise. The sound persisted when I switched inputs between hdmi/component, etc., whether or not any device was even connected to the input that was selected. The sound only stopped when I "muted" the tv, not even when I lowered the volume to zero, manually. I turned off the tv and turned it on again, and it was fine for a few seconds until it started again. I cut power to my entire system, waited 10 minutes, started it up again, and now it's been fine. But, I'm scared there's a problem that will recur and that it's only a matter of time.

Any thoughts at all from anyone?????? Any advice whatsoever would be greatly appreciated!
