Hi everyone,

 

Since the last OS SW update for webOS 23.2050 for my OLED LG TV 65C3 I have noticed a weird problem where the TV randomly shuts down by itself while watching TV, Netflix, YouTube … I couldn’t find a pattern when and how this happens it seems to behave like this randomly. I

t’s like.a SW crash behaviour memory leak or something (just an assumption).

I mention this is not the energy saving auto power off feature.

Have you guys encountered such issue?

Hello Dinoc, I am also a user of a LG C3 65OLEDC3. I have recently upgraded to 23.20.50 like you. Everything is working fine. Except that sometimes there are some short interruptions on different streaming platforms like Netflix or Fubo or even Youtube. BUT the TV is not rebooting. The worse is that recently I got a kind of 30 secondes retro feedback on Netflix and Apple TV (I mean, I was looking at the TV when suddenly it went back to 1mn ago in a series). No SW crash, no rebbot ... Could i be a fiber issue ?

Information about the reasons for turning off the TV (due to problems with the equipment or a normal shutdown with the remote control) is stored in the logs of the TV service menu. You can look there and evaluate what causes the shutdown. The decoding of the codes is here:

Hi, Vladimir,

 

So I need a special remote to enter the service menu? I only have the LG Magic remote (I don't see any in-start button there).

Hi BozaB, did you also upgrade to a recent webOS version just after the C4 installation ? You can check that in the setting (wheel) menu from the magic remote. You can also see if you have notifications to ask you some actions (like updates).  I suggest that you update to the latest version that you can (for the c3, this is the 23.20.50). I don’t have it for the C4 … Also, I only have 2 devices connected to my LG Tv (a box and a sound system). I suggest that you disconnect some of these devices (one by one) and check if you still have the issue.

I haven't resolved the issue, the local service support asked me to reset it to default and monitor, did it but it does the same thing, randomly resets itself while watching Netflix, Max or Youtube.

I tried the service menu but I couldn't understand it was not able to see the reason for reset.

Yes I updated to latest update, unfortunately after few days of trying everything I can think off, I called customer support, and it turned out if you believe it or not, I bought new tv with factory broken motherboard.. Thank you for the help.

I contacted the local LG service center and they changed the motherboard for the TV (under warranty), hopefully the new one will work fine.

      International contents from JioCinema and Hotstar Apps are not playing on my new 48inch C4X OLED TV
      By Nihar Ranjan Dash
      The international content on JioCinema and Hotstar apps are not playing. No issues with Indian content in Hindi or other regional languages. But English, Korean, and Japanese content are not playing. Specifically, I want to play Disney content on Hotstar and HBO content on JioCinema App. 
      I tried resetting all configurations and reinstalling the applications and re-logging into the apps. Still, the issue persists. I tried switching off the TV and tried pressing the power button for complete discharge and rebooting my router, but the same issue persists.
      **I found a workaround though, changing the wifi network or using a mobile hotspot on TV and then all content plays well even if I revert to my primary Airtel wifi, It still plays. but the next day the same issue continues.
      It's an overhead to switch the wifi every time I want to watch Hollywood titles. Certainly, it's not the experience I want with a TV of a hefty price tag. No other devices (Mac, ios, android, windows, Android TV) have this problem. Also, it's not the wifi issue, as I can watch the same titles on other devices. The LG TV also doesn't have the capability to remember a few WiFi networks to ease this workaround of switching networks.
      Alas, Nobody informed me about this issue earlier while making the purchase. Now such pricey TVs shouldn't have these issues at all. Kindly let me know If there is a permanent fix for this issue.

      LG’s World-First Transparent and True Wireless 4K OLED TV Delivers New Screen Experience
      By News Reporter
      Transitioning Between Transparent to Opaque Screen, LG SIGNATURE OLED T
      Introduces New Viewing Possibilities and a New Era in Home Entertainment

      SEOUL, Dec. 19, 2024 — LG Electronics (LG) is set for the global launch of the 77-inch LG SIGNATURE OLED T, the world’s first transparent and true wireless 4K OLED TV. This groundbreaking model will be available in the U.S. this December, with additional markets to follow.
      Unveiled at CES® 2024, the LG SIGNATURE OLED T represents a monumental leap in both technology and design innovation, reflecting LG’s relentless drive to delivering new and better. Its cutting-edge self-lit screen can transform from transparent to opaque screen; a unique ability that provides the OLED viewing experience while offering greater freedom in living space. Recognized globally, LG’s transparent OLED made TIME’s Best Inventions 2024 list and received a total of five CES 2024 Innovation Awards, including a Best of Innovation honor.
      Users can effortlessly switch between transparent and opaque modes at the touch of a button, unlocking unique possibilities for entertainment and space design. When in transparent mode, the OLED T offers a futuristic content experience that must be seen to be believed. The screen not only creates the illusion of content floating in mid-air but also produces a mesmerizing effect by “merging” the on-screen visuals with the surrounding space.
      LG OLED T further elevates the user experience with a suite of versatile features that optimally leverage the unique advantages of a transparent OLED screen, enhancing its distinctive value.
      One standout feature is T-Objet, an Always-On-Display (AOD) mode that transforms the screen into a transparent digital canvas, ideal for showcasing artwork, videos or photos in outstanding color and clarity. Complementing this is T-Bar, a sleek info-ticker that appears along the bottom edge of the screen, providing sports results, IoT device statuses, weather forecasts or song title information. The rest of the screen remains unused when T-Bar is active, presenting a clean, uncluttered look and a clear view of the space behind LG’s “virtually invisible” display. For added convenience, T-Home offers a user-friendly interface that delivers a well-organized overview of available services, as well as quick access to apps, settings and other features.
      Despite its stunning 77-inch screen size, the LG OLED T enhances the feeling of space within a room, providing a sense of openness that conventional TVs simply cannot. Its transparency allows it to be placed centrally without being obtrusive or positioned in front of windows without blocking natural light or views of the outdoors.
      The transparent 4K OLED screen, combined with LG’s true wireless video and audio transmission technology, promises not only the aesthetic value but also an enhanced home entertainment experience. Free from tangled cables, the device delivers an immersive, distraction-free viewing environment.
      The OLED T advances innovation with LG’s proprietary Zero Connect Box, a visually lossless wireless video and audio transmission solution* without latency ensuring a seamless viewing experience. By supporting 4K at 120Hz variable refresh rate, OLED T has been certified by NVIDIA G-SYNC® Compatible and AMD FreeSync Premium to eliminate tearing and stuttering for the most dynamic, true-to-life gaming experience.
      The LG SIGNATURE OLED T carries forward LG’s legacy of providing superior picture quality and immersive viewing experiences – hallmarks of LG OLED TVs since the very first model hit the market in 2013. Building on over a decade of OLED innovation, LG’s one-of-a-kind TV brings images fully to life with vibrant, precisely reproduced colors and incredible contrast. Powered by LG’s advanced α (Alpha) 11 AI processor, the OLED T intelligently optimizes both picture and sound quality, delivering unparalleled visual and auditory experiences.
      “LG SIGNATURE OLED T is an exceptional user-focused innovation that offers a distinctive, multi-faceted viewing experience and unprecedented spatial flexibility,” said Park Hyoung-sei, president of the LG Media Entertainment Solution Company. “LG remains at the forefront of innovation by combining its industry-leading OLED technology with unique form factors, transparent screens, wireless connectivity and more, delivering unparalleled, life-enriching advancements no other TV maker can replicate.”

      2025 LG QNED Evo Transforms With Core OLED TV Innovations: True Wireless, AI and Hyper-Personalization
      By News Reporter
      Based on Company’s Dual-Track Strategy,
      the 2025 QNED evo Lineup Boasts Unprecedented Technological Advancements

      SEOUL, Dec. 18, 2024 — LG Electronics (LG) unveiled today its renewed 2025 QNED evo lineup, featuring new proprietary wide color gamut technology, a true wireless viewing experience that transmits 4K 144Hz1 images without loss of picture quality or delay, AI-enhanced picture and sound processing, and an ultra-personalized AI-based customer experience via webOS 25.
      LG continues to strengthen its competitiveness in the global premium TV market through a dual-track strategy. This strategy emphasizes LG’s market-leading, self-emissive OLED lineup and the QNED evo series – a premium LCD TV lineup that incorporates key OLED innovations, such as advanced AI capabilities and wireless convenience.
      The 2025 QNED evo lineup boasts an improved color gamut compared to previous models by applying LG’s new proprietary wide color gamut technology, Dynamic QNED Color Solution, which replaces quantum dots. This unique technology enables light from the backlight to be expressed in pure colors that are as realistic as they appear to the eye in general life.
      With the application of Dynamic QNED Color Solution, the entire 2025 QNED evo lineup is 100 percent certified by global testing and certification organization Intertek for Color Volume, measuring a screen’s ability to display the rich colors of original images without distortion.
      In 2025, LG will also unveil the QNED evo (QNED9M) featuring its True Wireless 4K technology. This innovation, previously exclusive to the top-tier OLED evo model (M Series) last year, will now be available in the QNED evo lineup. This expansion allows viewers to enjoy high-definition 4K content wirelessly, without compromising on picture quality or experiencing delays, moving beyond the limitations of traditional wired connections.2 The wireless solution utilizes a separate Zero Connect Box to transmit high-definition video at up to 4K resolution and a refresh rate of 144Hz. The QNED evo is designed to minimize screen disconnection and deliver natural images even in a wireless setup. Additionally, it has earned AMD FreeSync Premium certification. The TV itself requires only a power cord, allowing for more convenient storage of gaming consoles and set-top boxes.
      The company additionally continues to raise the picture and sound quality of its QNED evo lineup by offering more powerful editions of its proprietary AI processors. 2025 LG QNED evo models are equipped with the α8 AI Processor, offering close to 70 percent improvement in AI performance compared to the previous year. This processor delivers picture and sound at a level worthy of ultra-large TVs.
      These AI capabilities include more advanced upscaling, analyzing the filmmaker’s intent to adjust picture noise and presenting faces, objects, text and backgrounds more naturally. Dynamic Tone Mapping Pro breaks down each scene to fine-tune HDR effects and brightness for each zone. Moreover, AI converts 2-channel sound sources to virtual 9.1.2 channel sound for a richer audio experience. It also distinguishes voices from background sounds and makes them clearer, while audio sounds natural as if it were coming from the center of the TV screen.
      The new AI Magic Remote, included with the 2025 QNED evo, features a new AI button for easy analysis of viewing preferences and recommendations on what to watch and which apps to use. Personalization is further enhanced by Voice ID, Generative AI Gallery3 and customized TV picture and sound quality modes. A short press on the AI button guides users to relevant keywords and TV features, while a long press enables personalized searches based on a large language model (LLM4). For example, if a user is planning a trip to France, they can ask their remote, “Recommend movies to watch on my trip to Paris.” The AI will understand the context and suggest movies set in the French capital, including specific genre recommendations based on the user’s viewing preferences.
      LG’s proprietary smart TV platform, webOS 25, elevates the customer experience by offering hyper-personalized service advancements and content through its best-of-all-time AI features and the ongoing webOS Re:New Program, which includes webOS upgrades for five years.
      The 2025 QNED lineup will also now range from 40 to 100 inches as LG is expanding its QNED lineup by introducing a 100-inch option in response to customer demand for ultra-large, premium LCD TVs.
      “Our renewed 2025 LG QNED evo lineup inherits OLED’s differentiated picture quality along with a true wireless viewing experience and ultra-personalized solutions to deliver an outstanding super-large viewing experience that no other LCD TV can offer,” said Hyoung-sei Park, president of the LG Media Entertainment Solution Company.

      Why is my LG TV SmartShare (Media Player) program randomly changes to Sharing OFF on Windows 10?
      By wallyricks
      I have owned a couple of LG TV’s over the last 8 years, with the current one being a high-end 77” model.
      I am still using LG TV SmartShare (v.33) as my “Media Player” v2.3.1511.1201 for my PC– which was last updated in 2015 but it is still compatible today.  As proof, my latest TV is now 11 months old and I have had zero issue (until you see below).    
      link hidden, please login to view My PC setup is: Windows 10 Pro (with all latest updates) and a TP-Link Archer BE19000 (BE805) router.    NOTHING has been changed on my router, TV (no updated or changed firmware) or any equipment moved around in the last 4 months.
      Up until about 3 weeks ago, everything ran just fine.  The SmartShare program was always defaulted to have Sharing ON, upon start of it, which is always when Windows boots).  However, about 3 weeks ago, the SmartShare PC program has started to randomly change its status to Sharing OFF.  I would then have to go into the program, manually change it to ON and then it works anywhere for 30 minutes up to 20 hours, and again, randomly change the Sharing to OFF.
      I am an experienced PC user, and I am very sure that this has nothing to do with my WIFI because it’s not a dropped connection or random TV not being found.   Something is happening inside Windows 10 that is triggering this status change.  And it never fluctuates back to Sharing ON by itself.
      Being so frustrated, I actually updated the Router to the latest firmware a few days ago, but this problem continues as before.
      As an experiment, I installed an alternate Media Server program called Serviio.  One can also see that when my Sharing changes to OFF, the two green lights turn red.
      Anyone have an idea of what can be happening after nearly 8 years of not experiencing this?       I am guessing that Windows is triggering some “Service” to stop running, but what can it be?
