Samsung: sound distortion on new LN22A451
Confirmation of power related problem
by SLR42 - 11/30/08 7:24 AM In reply to: Thanks, and noted! by Samsung_HD_Tech
Ironically, shortly after I posted my analysis, we had a power failure in our neighborhood, and sure enough, the robot audio reappeared after months of perfect operation. I tried someone's suggestion of resetting the audio settings by turning each one off then back on, but that had no effect, so I am now in the painful process of resetting up my TV. Fortunately I took pictures of all of the setup screens before the repair tech replaced my board.
What suprises me
by rvrichardson - 11/30/08 7:36 AM In reply to: Confirmation of power related problem by SLR42What surprises me, is that with all the experts at Samsung and the fact that they monitor this forum, the fact that we have all but given a solution to this problem, I still am faced with the aggravation of having to go through this whole reset scenario every time I encounter a power issue.
Come on Mr. Samsung.... give us a solution....

Yeah, that was my suggestion about resetting the audio section only.
So you reset all of them back to the default positions and no luck?
I was also wondering whether having the "jingle" (that's heard when the TV is turned on or off) eliminated would
have any affect on the situation. Luckily, I haven't run into the robots yet, so I can't check these nutty theories out for myself.
Your memory chip hypothesis seems the most logical cause as of now.
Power out--robot audio back
by Satnamji - 11/30/08 5:09 PM In reply to: Confirmation of power related problem by SLR42A couple weeks ago I successfully reset my TV to factory defaults, thus "fixing" the robot audio. Well today I foolishly made toast while my washer and dryer was running, tripped a circuit breaker (TV was off at the time), and sure enough robot audio is back! 
What have you found?

I too have this audio problem. It's disturbing that the original post was 7/25/08 and you have responded 13 times over the last 4 months and you still have not come up with anything of substance. On 10/29 you indicated that you summarized all the problems to bypass regular service and escalate it. That was a month and a half ago! That's not escalation that's just talk. Numerous people have detailed how to reproduce the problem and how to temporarily fix it yet nothing of a permanent remedy has been brought here. Please try to help us enjoy your products without feeling like we want to put a brick through it.

FInding a defective set

That's not exactly correct. People can reproduce the audio problem with their particular TV....but a hundred others might not be affected by this. So, to just reproduce this in a lab isn't all that easy. They'd have to get ahold of a KNOWN defective set to work with before making any headway. Maybe someone should voluteer to ship theirs to the main service center at Samsung. I would, but so far mine is OK.
Audio Issue
by izkeh - 12/10/08 7:14 AM In reply to: FInding a defective set by jsganzI think the main issue here is that Samsung_Dude has gone quiet.
There is way more than enough info on this thread to be able to attempt to reproduce the issue. Moreover, Samsung KNOWS what their failed TV's came back for. There would be, one could safely assume, a database of all serial numbers and where they are in the service queue as well as what the failure is on them. I refuse to believe that there aren't several in there that exhibit this issue of which they can pick from. Plus, we aren't even talking about all the shotgunned PCB's that the "service techs" in the field have sent back for warranty replacement.
Again, from my standpoint, the issue isn't so much that there's a issue, it's that NO ONE from Samsung is actively participating in this thread. What little participation there is lacks substance. Tell us where things are at wrt this audio issue. Telling us that you are going to "move it up the chain" or whatever is all fine and well but there needs to be updates, man. UPDATES!!!
Have a little patience and revise your 5 star reviews!
by Satnamji - 12/10/08 10:22 AM In reply to: Audio Issue by izkehIt seems, according to the post above, the last time we heard from Mr. Samsung was less than two weeks ago, Thanksgiving weekend (11/29)to be exact. He says he regularly monitors this thread, so how often do you expect him to post to just say, "Still no news from Samsung laboratories"? I know this problem has been festering for months, but I don't think hounding him for updates will help matters. The most we can do is continue to update the state of our own sets, especially if it got serviced by Samsung and the problem came back, and encourage others to report the problem.
In the meantime, those of you who gave 5 star reviews for their A450 on various Web sites before the problem surfaced, go back and revise them (if you haven't already) and jump in on discussions on AVS forums and others when someone posts a thread asking advice on whether they should buy Samsung or Sony or whatever brand of TV.
Expectations
by izkeh - 12/11/08 5:23 AM In reply to: Have a little patience and revise your 5 star reviews! by SatnamjiI expect a forum monitored by a Samsung employee (or contractor) to be given regular updates on existing issues. Regular means at least once a week. My expectations are not out of line. If my customers didn't hear from me in 2 weeks on a forum I monitored (which I DO) I would deserve any bashing I got.
Not only is there an issue that has been reproduced ad nauseum there is minimal response to the issue. I take exception to your comment about what is he supposed to do come back and tell us that nothing is happening? YES!! Yes, he should come back and at least let us know where it's at in the system. Is it being reviewed by Engineering? Is it being reviewed by Lab techs? Is nothing happening? And, if so, why is nothing happening. These are ALL perfectly reasonable expectations from a forum sponsored by and monitored by Samsung and paid for by us who purchased their products in good faith. Get it???
Many sets may be defective but undetected
by SLR42 - 12/10/08 8:13 AM In reply to: FInding a defective set by jsganzYou forget that this problem only occurs on sets that are directly connected to the cable outlet. According to Comcast, over 70% of their customers have cable boxes. These people, and those on satellite services, would never see this problem. Also, I suspect that most people who buy HDTV sets also have cable boxes, because they have been led to believe that they can't get HD programs without one. So we may be a relative minority of Samsung's customers. This does not absolve Samsung of responsibility to fix the problem. Also, we are a noisy group, and if Samsung gets a bad reputation for quality, it will take them a long time to get it back. Having Best Buy and Circuit City sales people steer customers away from Samsung products can't be good for their business.
Small percentage actually detects this audio problem

Absolutely right! Besides that, even if they weren't using a cable box,
they still have to UNPLUG their TV for some reason.
Then (& only then) will they even realize they have a defective set. So, we're really getting down to a ultra small percentage of owners. That's the basic problem with this whole situation!
Many undetected bad sets

Seems to be fixed
by jeffm1984 - 1/20/09 8:34 PM In reply to: Thanks, and noted! by Samsung_HD_Tech
I have a Samsung LN32A330, and I was also experiencing the reverb distortion on HD channels. I did the factory reset and so far it seems to be fixed.
But I'd certainly like to know if and when a more permanent and official fix is released. Mr. Samsung, can my account be added to a mailing list to notify customers when that fix is found? Thanks.
Aside from the former reverb problem, this TV is sexy, and I'll definitely be keeping mine. 
Works great for now
by Peridot180 - 1/20/09 8:51 PM In reply to: Seems to be fixed by jeffm1984We also have the Samsung LN32A330 with the robotic audio problem and did the factory reset as suggested on this forum and others. It works perfectly now with no audio problems. Hopefully we won't have any power outages or glitches, although it worries us because our house has poor electrical wiring and is prone to random power outages. I just hope this lasts...
I agree that it would be nice to know what is being done about this problem and if a permanent solution will be found. I agree that this is a sexy TV and I don't want to replace it. Samsung tried to pull a fast one on us by sending us an e-mail wanting to replace our TV with a cheaper, inferior model. We declined the offer and will just wait and see what happens. If the sound issue stays gone with the factory reset, we will be very happy, but I guess that isn't a given.
Robot Noise
by jjthenovice - 12/9/08 4:55 PM In reply to: My opinion on where the audio problem lies by SLR42If this is the case, then just doing a channel rescan should work but it doesn't. I still think you're on the right track.
