Lip Sync Problem


MAUICUDA

Question

Great picture but how to fix lip sync problem, only on ABC network channels, coming from Spectrum Hawaii?  Same cable box into my older Panasonic Plasma, using same HDMI cable: do NOT see lip sync problem.  What am I missing, or what is different coming in on the cable that bothers the LG set but does not   bother the Panasonic TV?

I have the lip sync problem too and based on my search for an answer there are lots of people who have this problem.  The one workaround I have found is turning off the Dolby sound output from my directv box and changing it to PCM.   Of course this means I have no Dolby sound to go along with the beautiful picture, but at least the sound is not 5 seconds behind that picture.  It sure would be nice if someone from LG would post something about this, if not a solution then at least an explanation of the problem.

Contacted Costco Concierge service AGAIN, finally got some action! They contacted LG Tech support (professional level tech support, not consumer level tech support?), they in turn contacted local TV repair shop, which I presume is under contract with LG and/or Costco. Technician brought proprietary hand held remote control (which required LG provided 4 digit pin to activate/log in to control my set. Changed an audio setting from something to PCM -problem solved. Wish that LG had provided the ability to change that setting with my personal remote.

Woke up this morning to discover that I too have sound sync issues on my 8 month old LG 49SJ800V.  To say I'm unimpressed would be an understatement particularly considering that it's only the internal speakers I'm using and not some external source such as a soundbar. 

I Googled the issue and tried a number of tips, the most popular being fiddling with the AV Sync Adjustment. Upon adjustment the sound and picture will sync up but only for a few seconds before it loses sync again.  The problem is compounded by the sheer number of sound options and permutations required to be gone through in order to try and find a solution including software update enquiries.

I eventually waved the white flag and rang  LG Customer services. Long story short, I was advised to go to the 'General' setting and select 'Reset to Initial Settings'. I did as advised with all the brouhaha associated with setting up the TV from scratch again (internet settings, picture adjustment etc) and the problem appears to have been resolved - for now. 

Hopefully that's the problem sorted but if there are any unwanted further developments I'll post again.

      I can stream ABC content using either the iView app on our LG G1 65" OLED, or via the iView Android TV app that is installed on a Chromecast with Google TV that is plugged into one of the G1 HDMI ports. If I stream content using the app on the TV, every few minutes there's a momentary (fraction of a second) interruption to both sound and video. If I stream the same content using the app on the Chromecast, I get no such interruptions. Both TV and Chromecast are using wired Ethernet connections to the same switch, so I can't see that these interruptions are due to a network problem, or I'd see them on both devices. It would seem to be a problem with the app provided on the TV. Other streaming services that we access via apps on the TV (Netflix, Stan, Amazon Prime, etc) do not show the same problem.

      I have a NANO91ANA LG TV connected via HDMI to a Yamaha RX-V677 Receiver. Normally when I turn the TV on it also turns the receiver on and I can control volume via the LG remote, whether it is an app on the TV or from another device connected to my receiver (Apple TV or cable box). Now the receiver is not turning on and ARC audio is not working. I think there may have been a software update the other day, but I'm not sure. However, everything was working properly until last night. The last time this happened it seemed to correct itself (it seems to be kind of sporadic), but this time it did not. I do not know what to do to correct this, but it is a major pain as I'm now having to deal with 4 remotes, plus I can't get sound out of my surround speakers when using an app on the TV.  Any suggestions would be appreciated.

      When i start my tv it boots up at HDMI 2 ARC which is the last one used and the one I want to use (Sound bar/apple tv connected), but then the tv changes to HDMI 4 and I don't understand why because there's nothing connected to it. It does this every time. I start my tv via my apple tv remote. Is there a way to force HDMI 2? Set it as default?

      I have a LG OLED C8 TV with a Soundbar and when connected to Optical the Volume Control is normal with a Percentage 0% to 100% but when connecting to HDMI ARC port like the Soundbar suggest to be connected it just show + or -,  you don't have anyway of knowing what the volume is set  to.    I have tried two Soundbars a LG LAS551H that was connected via Optical and when connected to HDMI ARC it also does not show Volume Control.  I have  got a new Sonos Beam Gen 2 that is now connected to HDMI ARC port and sounds great but if I connect it to Optical it's much lower in volume but has the Volume indicator.   Please advice.    
      I would like to suggest three enhancement request: 1. to show Volume Percentage on the HDMI ARC port.  2. Optical and HDMI ARC have the same output and 3. the Sonos be added to the Device list under Soundbars. 
      Thank you,

      It'll detect the laptop on HMDI1 or 2, but when I switch to it, the laptop doesn't show on the TV. This used to work. 

      I tried different laptops, different cables, no luck.

      I'm wondering if this is caused by a WebOS update
