Summary: just got the 48inch Samsung 6700 and its incredible. I was a bit worried about lip sync issues having read some of the other reviews but my TV has been perfect on all channels with no adjustments needed at all. It looks great, and is so easy to set up, you just turn it on and follow the onscreen instructions and you're watching within a couple of minutes.
Summary: Purchased this from JL (obviously) and must say picture really good but even with the latest update (2116) the problem with lip sync still persists. Tried to get on ok with the set but could not deal with the problem. Contacted Samsung and told they are aware but reading the reviews it is a problem they do not seem to be able to remedy. Contacted JL customer service and they really are first class. Unfortunately I have had to return the TV.
Summary: I recently bought this TV together with the M5 speaker. very disappointed. The TV picture is fantastic, and the TV looks good but basically it is not possible to watch the TV due to the problems with lip sync. These problems are made much worse when using the M5 speaker. Unless the problems can be resolved I will be returning the TV and speaker to the shop and looking to purchase a competitors TV as a replacement. Samsung not up to your usual quality and experience.
Summary: In many ways this is a very good television, but like some other reviewers the basics can let it down. I am not a highly sophisticated user, so some of the more advanced features are redundant, but many of the features are great even for me.
Summary: This is a great buy and it has changed my viewing for ever I think. The HD is much better than I have experienced in the past and it has 3D too. The voice control takes a little getting used to but I should be an expert soon. Great choice from me and great delivery service from John Lewis. Driver phones on your mobile to make sure that you are there to receive it.
Summary: HD picture quality is generally good, however when streaming HD videos from Amazon etc the quality dips and looks almost SD with seriously crushed blacks and greys. SD video is about what you would expect on a screen of this size (48") but it's biggest fault is lip-sync! Historically this is more a problem in HD but this set reverses the problem and appears more commonly in SD channels.
Summary: I was worried before purchasing because of the reviewer who had lip-synch issues, but the TV has had two over-air updates since I purchased it, and I haven't seen one single instance of lip synch problems since then. A quick look around the AV forums online confirms that this has been sorted out with these updates.
