Vizio E601i-A3 60-inch LED HDTV - lip sync issues

post #1 of 13
Thread Starter 
I have been experiencing occasional lip sync issues. It seems there are a lot of people having them. Some find that they are always out of sync, some only with some channels, and some it just happens occasionally and changing channels and back will fix it. The latter is what I am experiencing. There are several people that talk about this in reviews on Amazon, and there is a long forum discussion about the TV here where a number of people address this problem, but it is a bit confusing as there is a lot of discussion about other thing as well. I think a post dealing with just this problem might be helpful.

I am getting new boxes that Comcast is coming out with next week and have ordered new HDMI cables to see if this might take care of the problem as these are areas people have speculated are causing the problem. It seems strange it is sporadic and can be rectified by switching channels. I am thinking it has something to do with the signal coming from Comcast and this TV, but it is only speculation. I have no lip sync problem on the 2 other TV's in the house.

I have the 70" so it is not just the 60" that has this problem.

If you are having problems or have solutions let's talk about it in this post.

I would like to know what source other people are using that are having the sporadic problems. Could it just be Comcast?

I have seen it on ESPN on DirecTV. Changed channels and went back and it was gone. That's all I have seen. For 688.00 I can put up with a little lip sync. I use only the TV speakers, no external speakers

I have it with OTA Signal. I do not have Cable. It is a TV problem. Not your boxes.

Yep it is a shame about the lip sync issue, just to note the E500i-A1 does not suffer with this issue at all. I have it connected to the internet and my provider is Directv. Has anyone found out if Vizio is working on a firmware fix?

I bought the E601i-A3 60 inch at Sam's for Christmas, and it had the occasional lip sync problem, I hooked it up to a Vizio sound bar with wireless Sub Woofer, and it was still going out of sync but it had to be on a certain channel for about an hour before I noticed it. Changing the channel and then back immediately cleared it up for another hour or two, sometimes 3 or 4 hours even but it would eventually come back.

My Vizio was playing on Christmas Day when it just decided to go black.... no picture.. poof, no noise, no smoke, no hiss or flashes , nothing it went from a great picture to a black screen in less than a second.... The sound kept on playing, and if I walked up to the TV I noticed it had a very dim bluish light to it, like a blueish hue all over, but Im sure it was a light. The set worked for 2 weeks.

I did the resets, and all they say to do and nothing brings it back i'm sure the video processor or something in the video board went out as the sound still works well. Vizio is sending me a new one, and said they will pick up this old one... It's not really old, it was bought December 10, and it crapped out on December 25th...

But as far as the lip sync issue I talked with Vizio about it when I called, and they are aware of it on this model, and told me they are looking for a solution to the problem...so who knows...but it's not a cable box issue, or an HDMI cable problem, and changing all the settings on the Audio doesnt cure it... it's a problem in the TV itself.... Hopefully if hey isolate it they can issue a firmware update to fix it maybe....

Basically I like the TV it is built solid, has a nice slim frame, its very thin, just an inch thick and has a very good picture with eye popping colors and deep blacks..... at least the set I have had deep blacks and very vivid colors.... This problem reminds me of the Samsung Plasma sets of a few years ago that were emitting a high pitch hum noise and some were worse than others and I never did see a fix for it, so I just avoided that set as much as I would have enjoyed it.... Hopefully Vizio will come up with something for this lip sync and premature picture failures as well...

UPDATE: I have confidence in Vizio, and I went up to Walmart and I bought a 32 inch LED tv so I have something to watch while I'm waiting the 2 weeks to get my 60 inch replaced. I was very disappointed when right in the middle of Christmas day my brand new 60 inch Vizio goes black, and I had a house full of company who were all watching a movie in the living room when it went out... Well...I heard a lot of "boooo's " and a lot of " what kind of crap tv did you buy" etc.... So thats part of why I was pissed with the Vizio. Plus it had the lip sync problem and I believe they all have it to a degree due to a component on the board that buffers the audio. Anyhow, this 32 inch LED is very nice, the colors and the sharpness are spot on, very easy to watch. It will go on the wall in my bedroom when they replace the 60 incher... No lip sync issues on this E320 model either I've watched it for 2 days and it has not skipped a beat with sync. This is how they are supposed to work...

I was told by the Vizio rep on the phone that Vizio is aware of the issue of lip sync, and is looking for a solution.. Whether or not that means firmware update fix or not I don't know she wouldn't say when I asked about firmware. I think it is possible but I believe these E601i sets are going to be like the old Samsung Plasma's that suffered from the high pitch squeal that never got resolved, some had it some say they couldnt hear it. I imagine it depended a lot on your hearing and what frequencies you can detect. So for Vizio, maybe firmware can help if it's a simple processing issue. Whatever is causing it, the problem goes away immediately if you change the channel, so that tells me it's not complex or it would be on all channels all the time...

Still not sure when everyone hears the audio delay... but it would make sense that the audio would be delayed if you use the digital optical output from the Vizio to run to your HT processor which then sends it back to your speakers. I run my sources audio digital outputs directly to my HT processor and mute the internal speakers on the Vizio and have heard NO lip sync problems at all. I also haven't noticed any lip sync issues when I simply watched TV via the Vizio using the TVs speakers.

It would make sense that taking an HDMI digital audio signal and then changing it to an analog audio signal(which is what we all actually hear) and then re-processing it to a digital audio signal for transmission out the optical digital to your processor for processing once again from digital to analog would create a bit of a processing lag in your audio versus the video which does not undergo so much processing and reprocessing?

I used the built in TV speakers on my Vizio, with no external audio hookups, and I still had lip sync problems.... it seems like it did not matter if I used the TV speakers, or hooked up the Vizio sound bar , the lip sync problem was there either way , so I have no idea what makes it happen.. or not happen with many people....

Hello, I too have the problem with lip sync on a 60" vizio. Same problem existed with the satellite receiver, blue ray player, or even the old VCR that I have. From what I've read, some say the HDMI cable needs to be 1.4 compliant. However, before I bought a new cable, I hooked up the input using component vidio and the problem still existed between video display and my sourround sound. If you use the speakers on the TV, there is no lip sync problem, but what fun is that. The vizio does have an optical audio output that will down convert from the HDMI input and will also up convert from the analog audio input. My surround receiver (Dennon) does have an optical audio input. So, I feed the TV with an HDMI cable and use the optical output of the tv to feed the sourround receiver and the problem is completely gone. The 5.1 sound is not lost in the down conversion, and of course, there is no 5.1 in the up conversion, but you still get stereo. Anyway, if you have an optical audio input to your amp receiver, this is one possible solution.

My Vizio E601i-A3 has a horrible unbearable lip sync problem when using the internal TV speakers. It's unwatchable.

That is good to hear. I've been procrastinating on even setting up my speakers until the lip sync problem is solved (either by Vizio or by returning the TV). I'll stop procrastinating, turn off the internal TV speakers and connect some external speakers to my Denon 1613 AVR forthwith to see if that solves the lip sync problem. I'll have the Denon send no sound at all to the TV. I hope that "fixes" it.

Roger,

Your post about the "lip sync" problem is about 10 months old, but I bought my 70" Vizio in September, 2013 and still have the problem. The tv signal comes through my Dish Network dish into the Dish VIP722 Dish HD box. From there it goes into my H/K 1625 A/V receiver.

I have maxed out BOTH the adjustment on the Vizio and in the H/K receiver and still have a 1/4 to 1/2 second lag.

Hopefully, you smart guys will find a way to remedy the situation, because I don't know what else to do. confused.gif
