I can't figure out if this is a cable or a tv issue, but the sound and picture on my new DLP are not in-sync? I feel like I'm watching an old Bruce Lee movie. Granted, I haven't gotten my high-def box yet, and this is a cable analog signal right out of the wall, but I'm not sure what the problem is? Has anyone encountered anything similar? Is there a fix? Is this a cable issue or a tv issue? Any advice would be greatly appreciated, as I've only had the tv a few days and it is starting to drive me a little crazy. Thanks.

I have the HLN5065, and Samsung is sending a tech out next week to replace "two parts". Evidently, they now are aware of the problem. I will let you know how it goes.

Aren't you gonna take your skates off?

thanks for the update. So are you saying Samsung believes that this is a tv problem?

The only time I have noticed sound sync issues is with DTS tracks on certain DVD's. I just assumed this was an issue with the Samsung DVI DVD player. I'm curious to see how your situation works out.

Two friends with CRT sets have this same lipsynch problem as I do with my Sammy DLP. It is not a consistent problem and can be happening on one channel and not another as I swap back and forth between the two. However, I cannot recall ever seeing it happen on a HD channel. I suspect it is a compression audio/video synch problem from the source and is not a tv set problem. If anything, I believe this has long been there but is just more noticeable on larger screen sets. I can see it happen as well on my 32" Sony Trinitron.

I agree. I see it on my OTA connected 27" Sony too. There are so many possible sources of sync problems that it boggles my pea sized brain. :(

Yes. What makes it really disturbing is when a tv commercial is, for example, showing a smiling woman holding her kitchen mop in hand and is describing hemoroidal wipes.

I have a Piopneer 50" plasma with HD D* service via a Sony HD200. I have noticed this on certain channels including HD channels. It is there sometimes and not others. I have even seen video delays...the video is running slow but the soundtrack is fine. I attribute this to programming issues, not hardware.

Baja,

How do you tell which one (sound or video) is delayed?

When it was video it wasn't actually delayed, it was almost like it was missing frames. It appeared as it was in slow motion but with missing frames keeping it up with the sound. Really weird, both times I noticed it it was with the same movie on HBOHD "Weekend At Bernie's"

For what its worth....when I purchased my first dvd player 5 or so years ago, I had terrible audio-sync delay. I took back the player and bought a higher end model, and the delay dissappeared. My point is... IMHO, I believe it is the source that creates the delay, not the tv.

Most of the audio-sync problems with dvds described here and in other posts seem to occur from those with the Samsung 931 player. One way to verify if its the source is to find those with the Bravo player and have them report problems, if any. If they have not, then we know the 931 is the problem.

As far as STB's are concerned, I cannot speak for those, but since the cable and satellite companies have started offering HDTV, they are compressing the s*** out of the rest of their signals which might be overloading the MPEG-2 algorithm.

Just some thoughts....

Many DLP users have noticed this AV sync problem. I had a 931, and took it back for a number of reasons, the sync issue being one of them (it was really bad with this player). However, when watching standard cable, HD cable, a DVD using my Sony 9000ES DVD player, or a D-VHS tape, there is still a noticeable lag in the video.

I am hoping for a call from the repair center this week saying that the parts are in.

I will keep you posted!!!

I have posted the same problem with my 567 on other threads. The video is delayed by at least 3 frames and sometimes more. I really hope there is a fix for it. I would have thought from a 5065 to a 567 they would have corrected the problem. I'm afraid that it's just the nature of DLP's.
I think HBO-HD always has a delay anyhow.

I just spent an extensive amount of time with the 567 testing it with various sources, and can tell you that this unit seems to have a serious issue with audio/video sync. DVD, cable or OTA the issue comes up in various ranges, but it is there no matter what the source. I have to believe that this is an issue with the unit itself and not the source.

Has any official word been said about this? It's a crying shame when you consider how nice the image is, but as a result of this I will wait for corrected models rather than getting stuck with this lemon.

I agree. I won't be able to keep my 567 with this problem.
What would everybody suggest as a replacement?

Have no fear of DLP's. They are unrelated to what you are experiencing. I can experienced the same thing with my Sony 27" TV. I'm not afraid of CRTs. ;)

jollyrodger...don't worry yet. As I mentioned earlier, Samsung is now acknowledging the problem, and has parts for a fix (atleast for my 5065). I will keep you guys posted once the tech comes out to replace parts.

If Samsung really does have a fix it probably means some sets got out with bad parts. If not, then they would be looking at fixing thousands of sets.

Include your experience here and it might be helpful.

I'll be getting the 507 soon, but these problems have got me quite nervous about this. My setup will be as follows: I use a Denon 3803 receiver for all audio. I'll never even hook up the audio to the 507. The receiver allows me to program an audio delay for every input to account for video processors, etc.

So my question is this... is the audio speeding up and slowing down in these sets or is it the video? If it's variable and its the video, then that will be fully unacceptable. If its the audio, I won't care at all because the set will have nothing to do with the audio. And if its just a video delay, as long as its constant (or even variable on a per-input basis), I can take care of it with the delay settings in the receiver.

But what I'm reading is that it changes over time. Is that right? That would be the one thing that I can't take care of and would be a major problem.

Source conditions have always changed over time.

If it's the source then "variable" is the name of the game. Check the link in the message above yours for other's experience.

I guess I'm not at all surprised that the video processing, the DLP chip, etc. actually takes a finite amount of time (if it turns out that way). Now if Samsung has an issue when using their own internal speakers, that would be bad. But if using external sound processing, I think that would be expected. Luckily, my receiver can delay the audio for for just this reason...

To the folks that are having the problems... what sort of display did you have before your DLP and for how long have you had your DLP? I suppose it's also possible that the delays have always been there, but at the crummy resolution we've been used to viewing at, it wasn't noticable.

I can't speak for everyone on here, but my experience is that some channels are delayed alot (HBO-HD for example), some a little, and others are almost in-sync (or more likely totally in-sync, only now my imagination is getting the better of me). All this leads me to believe that it is a source problem and not a tv problem. However, I guess it could have something to do with how the DLP processes different signals. I'm really hoping it's not the tv, b/c the picture is truly impressive (even on the non HD channels)... to me at least. In any case, I would be very interested to hear from DJDRock on whether Samsung has resolved his problem.

Oddly for me, it seems that my HBO-HD is about the best...meaning the least amount of delay I see. No call yet from the techs. Man I am anxious to see if it helps.
