I've been already reported a solution of this problem (at least here on my tv set):
1. Switch to external device
2. Reset TV (Press and keep pressed power on your remote till Samsung logo appears)
3. Sound problems are gone
Do you have to do that every time you want to use an external device? If so that is not a suitable long term solution. I would not want to live with that.
There are two solutions. The first by doing the reset as described, or more simply make sure you are on a standard definition channel before switching to a hdmi source.
I have with my set done what you say and it does cure it but if I switch from my external box in my case a Humax freesat receiver or even a brand new Sony blu-ray and go and watch a HD channel on the TV for a while and then go back to the Humax box the sound starts to break up again. I have spent a full day trying everything that I can and being an ex TV engineer with over 48 years experience has not helped me to sort it out. I was wondering if you can confirm its 100% cured. I dont want to send it back because the picture is so good. Pulling the aerial out does cure it but it is far from a satisfactory solution .
just a point of interest when i reported my fault to my supplier and asked if Samsung could possibly just change the control box or even get sombody to call and discuss the fault the salesman said that they would not help me because they dont admit or no anything about there being such a problem. That suggests to me they know about it but cant cure it.
Send it back to your retailer with a print out of these conversations. There is no satisfactory fix for this problem other than what has been suggested. Therefore, there is no permanent fix. If enough sets are returned to retailers then maybe Samsung will take note. It's disgusting that such an expensive product should have this fault.
Your retailer has a legal obligation to sort out the problem for you and cannot use the excuse that Samsung do not recognise the problem. Threaten to take legal action against the retailer in the Small Claims Court. John Lewis acknowledged their responsibility with me and refunded my money. Thank goodness I didn't buy through an internet supplier.
sending it back seems to be the only solution but the model is now discontinued so I cant even try annother one although it would probably be no better. Richer sounds said I can pay the difference and get the next model up but its quite a bit of extra money and I cannot see how it could be that much of a better picture to justify the extra cost. Plus I have lost my faith in Samsung for there lack of concern about the problem. I would also be wondering whether the sound would be fault free on that different model also. I help my son installing and hanging TV.s and I have always said to customers that the Samsung sets have in my mind the clearest and most fantastic pictures of all the different makes we install. Its sad now that due to a sound problem I cannot enjoy the product that I have always recomended and considered an excellent product.
Realistically the options are
- try to argue with retailers that the set is faulty, hope they allow you to exchange it for a non Samsung TV and don't insist on a repair (in my view there are few others in the same price range with as good a picture)
- change it to a non HD channel before switching to an external device
- do the reset thing which only ever fixes the issue temporarily.
- log the issue with Samsung through their official channel as they don't seem to monitor the forums, if everyone links this forum when they do and enough log the issue then maybe at some point we might see a software update that sorts it out.
For me the HD switching has done the trick and given how quick it is to do that over the time I've spent on a call with Samsung on a different issue when I first got the TV (which ended in an exchange) I'll continue doing that. It's not a perfect resolution but it is a resolution none the less.
It is a dilemma. I love the picture on the tv but i do not want to be taking actions, that should be unnecessary, to watch playback from recordings (which I do often) and dvd's. I have decided to go back to a Panasonic set which is being delivered next Thursday. I'll let you know what I think of the picture compared to the Samsung after I've installed it.
