HDMI/ARC completely dead after update to

Question

After my LGOLED55C7 updated to 04.70.85 I have l;ost all sound through ARC.

I have an Arcam AVR550 receiver which works for everything else and used to work perfectly (even with the latest Arcam update that provided Dolby Digital +).

Unfortunately after the TV updated to 04.70.85 I have lost all sound over ARC. The reciever switches to RC as normal when, for example, Netflix is started, It shows Dolby Digital + is being transmitted, but there is NO SOUND.

Any clues?

I have factory reset both the TV and the receiver :-(

I can also confirm this issue with my LG 86SJ957V. I was using Denon AVR-X1400H and my ARC was working without any problem.

After the 04.70.85 firmware update, no sound whatsoever. When I select the ARC/Hdmi in the TV it doesn't even turn on the receiver.

Should I wait for the next firmware or should I buy a media player?

Same here, I tweeted at @LGUSSupport but no big hopes: "Did something happen with a recent webOS update (04.71.00)? My OLED65C7P no longer outputs sound to my LG SJ9 soundbar in Optical/HDMI ARC mode. SIMPLINK is on, HDMI cable hasn't moved, had worked like a charm for a year+, but no sound as of a few days ago"

    • Question: Problem with voice instructions before update

      I have a TV LG 43UK6950PLB. Recently I updated to latest firmware version which is 04.10.04. When I try use de Magic Remote Control giving orders through the microphone, I receive a message like there is a problem with server temporarily and error 6022. I think is something about the update but how can return to previous version? Is this happening to someone else? Please give some advice. Thanks

    • Intuiface Announces Interactive Digital Signage Support for LG webOS Smart Displays

      CHICAGO, ILL. AND TOULOUSE, FRANCE (PRWEB) JULY 24, 2018 Intuiface, provider of the world’s premier interactive experience creation platform, is pleased to announce support for the LG webOS operating system. All multi-touch content created with Intuiface software can now be run on all smart devices running webOS 3.0, 3.0+, and 4.0, including the LG TC3D series of Integrated Touch Boards with PCAP (projected capacitive) touch technology. With this announcement, Intuiface provides multi-touch signage option for webOS, enabling businesses to invest in and to realize the added benefits of interactive over passive signage. Built from the ground-up with touch capabilities at its core, Intuiface is a no-coding software platform enabling any organization to create and deliver gratifying, purposeful, data-driven digital experiences that connect people to place, powered by the latest interactive technologies. Advantages of interactive digital content include deeper, lasting engagement thanks to real-time personalization and the ability to track user preferences in context, generating actionable business insights. Organizations adopting webOS devices for digital signage distribution can now use the IntuiFace platform, empowering them to create personalized, template-free visual content, incorporate live connections to cloud-based data and APIs (including social networks, IoT, Web triggers), and adopt all core capabilities necessary for successful signage and kiosk deployments such as remote deployment, fine grained user data collection and analytics, scheduling, and the ability to work offline. The marriage between the Intuiface platform and webOS is rooted in work by Intuiface to port its HTML5-based runtime (aka Player) to the touch-enabled webOS Web browser. The result - complementing Intuiface’s previous work for other platforms – enables users and partners to both manually access and remotely deploy interactive experiences simply by entering a URL. The combination of Intuiface’s unique capabilities with the dramatically reduced total cost of ownership achieved by SoC-based LG webOS devices creates a compelling low-cost option in the signage market for content creation, deployment, and monitoring. It is estimated that projects built with these two platforms will reduce total cost of ownership by 65% and time-to-deployment by 50% over conventional display and content delivery approaches. “Devices running LG webOS, coupled with premier PCAP touch technology, have a price point and convenience that make interactive signage deployments – the natural evolution of passive signage – an excellent choice for businesses of any size,” added Vincent Encontre, COO, Intuiface. “Thanks to our technology partnership with LG, Intuiface has been able to make interactive signage creation accessible as well. We believe the market will be amazed at what can be achieved, triggering a significant increase in interactive webOS-based projects.” “Giving LG digital signage customers the ability to create multi-touch digital content through the Intuiface platform is consistent with our strategy to offer the best technology currently available in the industry,” said Jongjin Woo, ID Business Unit R&D Head, LG Electronics. “For organizations in search of an affordable, accessible path to creating interactive digital signage – even organizations with no development skills - Intuiface and LG offer a uniquely compelling, turnkey package.” Interactive experiences built using Intuiface Composer can be published to a public or private cloud storage account and then downloaded and run, using Intuiface Player, on the PCAP-based LG TC3D Interactive Digital Boards as well as on any other LG display series running LG webOS 3.0, 3.0+, or 4.0. Both Composer and Player can be trialed for free – without a time limit – or licensed with an annual subscription. Information for getting started can be found here. About Intuiface 
      Intuiface is the world’s premier platform for creating, deploying, measuring and managing deeply interactive digital experiences without writing code.

    • My TV powers up and put the sound level at 100% by itself

      Hi, I bought a 47LB630V TV years ago, but since few weeks, my TV is going crazy. In stand by mode, it turns on by itself without any user interaction (by the remote controller or by the joystick button). Then, the level of the sound is increasing to the maximum. In the same time, it is impossible to use the remote controller for minutes. When it happened, some time, I managed to decrease the level, but then, it goes up again to the maximum. I tried to disconnect my TV from internet, perform a reset configuration. I also tried to downgrade the firmware (05.05.35 to 03.xx.xx). The problem stil occurs. It seems that somehow, it is like a program that forces the joystick button to move to left. When I am in the setting menu, and my TV goes crazy, the cursor is always put on the left-most element. Does someone already experience that ? It is like my TV was infected by a sort-of rootkit. Thanks,

    • Question: how to "forget/skip" wrong XPLAY update

      Hello,   I've read on the XPLAY forum about various problems with the latest version, so I decided to postpone the update until the issues are solved. I really don't know where the problem is but the developer said: "They have approved a quiet old version what has no online update functionality and the only way to fix anything or add new functionality is to send it to LG QA team … but they arrrrr soooooo much slow. Ive send them (on several days ago) version latest dev version with online update functionality. It will allow me to react to bugs much faster …"   My setup is: TV: LG 55EG920V, WebOS 2.0, Software version 04.25.70 XPLAY: 20180322.1.2.8 (ONLINE) PLEX: 1.13.8.5395   The version available for update in LG content store is 2.189.171 (08.10.2018). Many users complained they couldn't login anymore after upgrading to this version.   Could you please tell me what is the correct version should I update and when it'll be available for my TV? Also, is there any way to skip this update?  I just want to avoid an accidental update which would broke the functionality...   Kind regards,

      I have an LG 55SJ810V TV and Philips CSS5530B Surround Sound Speakers. The speakers work fine with everything except my LG ARC, including optical and BT from the LG and the ARC from a JVC TV, but I just can't get them to work off the ARC from my LG TV.  
      I have played around for hours with the TV settings. The Sound Out is set to External (Optical/HDMI ARC), although it often returns to default internal speakers. I've tried it with SIMPLINK on and off and the mode as Auto and PCM. Nothing sticks. I say sticks because I've had it working for a few seconds a couple of times, then it just goes off. E.g when switching cables from my JVC ARC to my LG ARC it worked for a few seconds.
      I've tried the Device Connector a few times, using either the Soundbar or Home Theatre set up. I've tried this after resetting the TV back to factory settings too. Nothing.
      LG customer services didn't seem too helpful and said a technician would call but if they do they're not quick!
      Any ideas would be much appreciated, otherwise it's going back for another brand because the twin tuner feature doesn't work as expected either (can't record one and watch another).

      Hey everyone,
      Can someone tell me if I'm going crazy?
      I've had this LG 43UH661V  TV for a while now.  I use it with my  Sony BDV-N5200W surround sound system, connected via HDMI ARC and it's great.

      The LG TV only has 3x HDMI, one of which is used by the surround sound.  The surround sound has 2x HDMI inputs that I can use, and switching to it on the TV, and then switching it's inputs allows me to effectively have 5x HDMI in my system, which is pretty good!

      I'm SURE that at some point when I was setting up the TV and surround sound together, I noticed extra devices in the input menus on the TV - like the TV was "seeing" the devices that the surround sound had on offer.  
      Am I imagining things?  Or is this a possibility?  If so, how the heck do I get it to work again?
       
      Thanks!

      I'm not getting any audio from the apps via the HDMI via ARC connection to my receiver.  This occurred two weeks ago and was unable to resolve it, but ironically there was new firmware released that same day for my B6 (3/31/17) and this fixed the issue.  However, now I again can't get it working after a TV reset and tinkering with the audio settings again.  I tried to load the firmware again, but it appears this is not possible to forceable load the same firmware.
