4k TV has serious lip sync issues

When playing my 65 inch 4K Sony TV I have serious lip sync issues.  Even when the 4K Media player is directly connected to the  TV via HDMI 4 and using the TV's own audio speakers the video lag is very pronounced.  Not a pleasure to watch.

 

It occurs on all content in the 4K Media player as well as Net-Flix and other apps too.  I can't find any lip sync adjustments in the TV's setup menu either.

 

Any Ideas??

Re: 4k TV has serious lip sync issues

Good afternoon jpburleson,



There are a number of circumstances that can cause the audio and video to be out of sync:

 

  • If watching a TV program, it could be the broadcast itself or a bad connection between your cable/satellite set-top box (if applicable).
  • If a DVD or Blu-ray Disc® (BD) player is connected, a poor connection or the disc itself could be the cause.
  • When connected to a home theater system with a digital optical cable, then there may be an audio delay that requires a manually adjustment on the home theater system. There may even be a setting on the TV itself causing this issue.

NOTE: Because each of the steps below represent a possible solution to this issue, check if the issue is resolved after completing each step.

  1. Make sure that the TV has the latest system software (firmware) installed.

    NOTES:

    • Not all TVs have software that can be updated. To see if your TV can be updated, check the specifications, which are available through the Manuals/Specs/Warranty link on this page.
    • If the TV is connected to a high-speed Internet connection, a software update can be downloaded from the menu of the TV.
    • If the TV is not connected to the Internet, click on the Drivers and Software link to download the latest update.
  2. If watching a TV program, try changing the channel to see if the problem occurs on other channels; if it only occurs on one channel, then the issue is with the broadcast.

    NOTE: If the issue occurs on one channel only, contact the broadcast network provider.

  3. Make sure all cables are securely connected to the TV and the source device (set-top box, DVD player, BD player, home theater system, or game console).
  4. Try playing a different video source to determine if the issue occurs with other connected devices.
  5. If your TV has a Game Mode setting, do one of the following:
    • Set the Game Mode to Off when watching TV or playing a DVD or BD.
    • Set the Game Mode to On when playing a video game.
  6. If issue is happening when using TV speakers, perform a power reset on the TV.
  7. If there is a home theater system and a digital optical cable is used in the connection, manually change the Audio/Video Sync or Audio Delay setting on the home theater system (if available).

    NOTES:

  8. Audio delay adjustments usually range from 0ms to approximately 250ms.
  9. For information about the availability of A/V sync or Audio Delay setting, refer to the operating instructions supplied with the product. Manuals for Sony® products are available online through the Manuals/Specs/Warranty link on this page.
  10. For a third-party home theater system, check the instruction manual or contact the manufacturer for information on how to adjust the A/V sync setting.

 

Please try these steps and let us know.

Re: 4k TV has serious lip sync issues

Thanks for the great and detailed reply.  I already know most of what you put in your reply.  You must go back and read my post again.

 

There is no need to go to look for lip sync issues elswhere when the tv is out of sync using your own Sony 4K media player playing back one or any of the preloaded movies.

 

Like I said the Sony 4K media player is the only thing directly connected to the Sony 4K 65 inch TV through the TV's HDMI 4 connection.

 

I see no adjustments either in the TV nor the Media player.

 

If it worked correctly with proper lip sync with this simple setup then I would progress into the rest of my system using the lip sync correction options available to me.

 

Everything preloaded on the Sony 4K Media that had dialog is out of sync.  And ****** I have tried multiple cables of different lengths and brands including the included Sony cable.

 

The TV and the Media player both have the latest published firmware updates installed too.

I have the same issue with a brand new x850b.  The lips are out of sync with the sound for all media sources.  This happens with the built in speakers.  I researched this issue and there are many people reporting the issue.  The "solutions" that Sony provides are not solutions.  For the money, I expect the TV to have built in tech to normalize any a/v sync issues.

 

I see the lip-sync error for all inputs I have:

 

- ATT Uverse 1080i -                     has lip sync error

- Netflix - 1080 and 4k content -  has lip sync error

- XBoxOne - HD movie content - has lip sync error

 

Hardware:

 

Tried multiple HDMI cables.  Same.

 

I followed the instructions to Factory Default the TV, which I performed multiple times.  There was no difference.  The issue is clearly inside the TV because its manifested with its own internal speakers.  And consistently the audio and video are about 250 - 500 ms out of sync.

 

From this I am beginning to conclude that either I have a bad unit or the 850B level of the Sony's TVs has this engineering flaw.  In either case, It is beyond annoying to watch TV with the words and the video to be out of sync.

 

Should I take it back or is there any hope of a firmware update fixing this?

Hello all,

 

I just purchased an XBR-70X850B, and I too am experiencing a delay with voice and picture.  Has anyone figured out a solution or do I simply return the TV and buy another manufacturer.  

 

Thanks in advance for any helpful response.

 

Jeff

 

 

UPDATE - UPDATE - UPDATE

 

OK, I spent a few moments connecting the 850B to my router and thereby connecting to the internet.  I then downloaded the most recent software update and voila`, the sync problem was resolved.  I will spend a bit longer just to confirm my findings.  But as it stands right now, problem solved.

I have just purchased Sony Bravia KD-55X8505B, and noticed the lip sync issue although I assume the television updated itself to the latest software version (PKG2.235EUA).

 

The lip sync issue is present in the TV broadcast and more pronounced in Blueray playback using Sony STR-1040DN AV Receiver and Sony BDP-S370 BD player when watching Avatar movie (that is a Sony title).

 

EDIT: OK, the lip sync issue I encountered appears to be related AV receiver audio settings and there was a problem with the TV broadcast most likely, too.
