43UJ630V - AUDIO OUTPUT SYNC GETS WORSE THE LONGER TV IS ON


Recommended Posts

If you want the whole story, read this: 

Otherwise, here's the relatively short and sweet version:

I bought an LG 43UJ630V  and a Samsung HW-K450 2 weeks ago.
When connected to the soundbar (either digital optical or HDMI ARC), they are in sync.
When left on for around 2 hours though, I'll start noticing the lips are not correctly syncing up with the words.
By the 3-4 hour mark being left on, it's atrocious.
I expect to have to have to set the av sync initially, but changing it every hour as it slowly drifts out of sync - this is clearly a technical fault.
When I plug the soundbar directly into my Sky box (set-top box) there are no issues of drifting audio sync.
Changing settings, updating firmware, using different wires, nothing makes a jot of difference unfortunately.

I determined the problem was with the processing of the digital output audio signal in the TV's internals.
I returned my TV for a replacement, and bought a new sound bar to go with it - an LG SH4D 2.1 - figuring that the samsung soundbar may have been incompatible.
Yesterday I set it all up, but found after 3-4 hours of being left on, the audio was wildly out of sync again.

In this example I set the audio so it would output via digital output and internal speakers. The latency between the 2 is so bad you can't even call it echo. This demonstrates how badly out of sync the soundbar output gets compared to the internal speaker.
Remember - this is my second 43UJ630V and a different soundbar, and yet the problem returned in exactly the same way.
After recording that video I tried connecting my Samsung soundbar instead and it was exactly the same.

There is clearly a fault with this model or the entire UJ630V range.
I hope it can be fixed in a firmware update.
Ignoring momentarily the fault, and the countless hours and stress this has caused - I rather like this model. I'd prefer to fix it instead of sending it back for a refund.

I don't understand why I cannot find anyone else reporting the same problems. When I spoke to LG a week ago describing the problem, they told me a fault like this hadn't been reported before... But I've proven beyond a doubt that the problem is there, and probably afflicts a great number of people.
I've emailed LG but I'm sure they'll just fob me off again. I plan to give them a ring later, but again, I'm not sure what good this will do.

I've diagnosed the problem, and I cannot be the only one experiencing this problem. It is probably addressable in a firmware update if I can bring it LG's attention.
Any help or suggestions would be appreciated.

Hi

i have a 43UJ630V and am being driven mad by the poor sound sync between the TV and my Sony Home Cinema, I connect via HDMI & Optical. 

Vision lags behind the sound typically by about 1 second or so, but it seems constant and doesn’t change with time. 

Move tried all sorts but can’t make any difference; it does the same whether I play a DVD on the Home Cinema, stream off internet via Home Cinema or TV, or watch tv with sound out through Home Cinema; clearly something is wrong!

Before the LG I had a Sony TV connected the same way and it worked perfectly. 

I suspect the delay may be with the upscaling of the images but can’t see any control. 

So although my problem is slightly different to yours, it does confirm something is wrong with the tv. 

Maybe the tv needs a control to change the sync?

I bought the oled65c7p and I have the same problem just with the tv, no sound bar or other sound equipment.  The tv picture is way ahead of the tv sound.  It seems to get worse over time.  All of the adjustments result in a temporary fix and it eventually reverts back to the sound being way behind the picture, so much so that the -5 adjustment is not enough.  I did find that disabling the Dolby output from my directv box  and changing it to pcm results in a synced sound and picture.  But now I don’t have Dolby sound, just stereo.  It seems the LG tv can’t proess the Dolby signal from the satellite box, my Samsung tv did not have this problem.

After struggling with this problem for almost a month I finally decided to send it back and get a different model.

I got a 50" 4k HDR Samsung TV yesterday and it's such a massive improvement. Didn't have to do any sound sync adjustment, it just works with the Samsung sound bar as you'd expect. So easy.

It' such a relief. I am over the moon with my Samsung.

I would recommend anyone who is experiencing the same or similar problems to what I described, send it back and get a different TV, preferably not LG.

LG have proven themselves entirely incompetent throughout this fiasco. It appears they simply don't care that an entire range/batch of TVs are faulty.

AS I Said in a post, LG is trying to sell its other devices ( LG Headphone, Camera,...), but it may loss even LG Smart TV market.

Matching these LG TVs with your favorite sound devices are terrible...

      Just getting the runaround from LG, only want a baseline figure, they sent me this
       
      , our technicians have explained that we cannot calculate the unit's actual power consumption when not in standby because there are too many factors that could affect this calculation. These factors include how many pixel refreshers are run, whether the unit is connected to the internet, external devices connected, speakers connected, sound systems connected, HDD connected and recording set ups. I am afraid that we consequently cannot answer your question.

      we all know LG are not helpful to customers , but there’s no need to keep proving it.
      this TV has a good energy rating so figures must be available, they either dont care or understand what I am asking
       
      thanks

      New Ergo Dual and Ergo Single Offer Easy Installation
      With Wider Range of Motion for All Professionals

      SEOUL, Oct. 14, 2021 — LG Electronics (LG) continues to push the boundaries of productivity, user-comfort and workspace flexibility in the modern era with its newest LG Ergo series of monitors. Perfect for home or office and anything in between, the LG Ergo Dual (model 27QP88D) and LG Ergo Single (model 32QP880) boast maximum adjustability, easy installation and exceptional IPS picture quality with QHD resolution (2560 x 1440).
      First unveiled a year ago, the LG Ergo series is designed to deliver a superior display experience with greater ergonomic comfort. The second generation models offer consumers even more value and versatility with improved height and swivel adjustability, making sharing the screen with others and working while standing easier than ever. Both new models continue to offer the same effortless ability as before to be set close to or far away from the user without having to adjust the mounting point. What’s more, the Ergo Dual offers a height-adjustable range of 150 millimeters while the Ergo Single travels 130 millimeters, with both able to rotate 335 degrees.
      With a wider range of movement, these monitors can better meet the individual preferences of every user. With a pair of 27-inch displays, the LG Ergo Dual can be set up in a variety of useful configurations including side-by-side in landscape orientation, one display in portrait and the other landscape, both stacked vertically or even facing opposite directions. The 32-inch display offered in the LG Ergo Single is ideal for users who prefer a large, seamless workspace.
      Both the dual and single models are now easier to install with articulated arms that attach securely without screws to desks and tabletops up to a maximum thickness of 75 millimeters. Requiring very little desktop space for a clean, uncluttered workspace, LG’s patent pending C-Clamp employs a slim, robust grommet allowing users to easily secure the stand on the edge of a desk or cable hole to get working (or playing) in no time. What’s more, both LG Ergo monitors can charge a laptop via the USB-C One Cable Solution while the Ergo Dual also allows displays to daisy chain via DisplayPort.*
      “The 2021 LG Ergo models are advanced workstation solutions designed to provide the ultimate in flexibility with all the display capabilities today’s advanced users demand,” said Jang Ik-hwan, senior vice president and head of the IT business unit of LG Electronics Business Solutions Company. “Both the Ergo Dual and Ergo Single offer next-level user convenience, premium IPS picture quality and an array of useful features consumers have come to expect from premium LG monitors.”

      SEOUL, Oct. 12, 2021 — LG Electronics Inc. (LG) today announced its preliminary earnings results for the third quarter of 2021.
      LG reported tentative consolidated revenues of KRW 18.8 trillion, an increase of 22 percent from the same quarter the previous year and the highest quarterly revenue in the company’s history. In line with current accounting standards, LG will include a provision of approximately KRW 480 billion in the third quarter for the recall of the Chevy Bolt EV. Operating profit of KRW 540.7 billion is expected to be 49.6 percent lower than the third quarter a year ago after reflecting the recall provision.
      LG Electronics terminated its mobile phone business at the end of July and is treating the Mobile Communications Company’ performance as a discontinued operating loss. Earnings for the previous year and the same period the previous year have been restated for comparative purposes.
      These figures are the tentative consolidated earnings based on K-IFRS provided as a service to investors prior to LG Electronics’ final earnings results including net profit. Details regarding each division which will be announced officially later this month.

      TV MODEL: LG 43UJ635V
      DATE OF PURCHASE: 21/11/2017 (4 days ago from post date)
      RETAILER: ARGOS UK
      WEBOS VERSION: Can't check right now but after I got the TV I updated straightaway to 4.7.XX
      INTERNET SPEED: 75Mbps Down / 20 Mbps Up
      Hello, I've recently purchased the LG 43UJ635V, as soon as I turned it on and went through first time setup I noticed there was a bit of lag in the animation when I pressed the home button (the moment all the tiles 'bounce' up), however whenever I get off that menu the animation is smooth and everything else is fine. This always happens, I have tried resetting the TV to its initial state and nothing has changed. - Just wondering if anyone else has had that issue?
      At one point I changed some of the image quality settings and the whole OS just started lagging making it difficult to navigate so I had to reset the TV  for the 3rd time.
      Also, occasionally when using apps such as YouTube or the web browser the app will restart with a notification in the top right saying the restart was to clear some memory. Although this isn't too common, I've seen other posts from months ago about people having a similar issue but the apps constantly restart.
      I close all recent apps which doesn't change the lag on the home menu but I haven't seen the restart notification in a while which seems like a good sign but I also have been using the internet browser much.
      With all the negative experiences I've read about, (related to the memory and general lag) I'm not sure whether I should return the TV or not.
      Thank you.
      TL;DR: Lag when pressing the home button and all icons appear but no lag when returning to the current app, occasional app restarts due to a low amount of memory.
