UB55850V menu doesnt display


KBOUM

Question

Hello,

 

I bought a smart TV LG55UB850v 18mth ago. When I turn it on, the LG menu "LG live's good" is ok, but few seconds later I can't get access to the settings menu, it doesn t display properly (just parts, or blinking/flashing) which means I can t even reset the tv to  factory settings  because I can t navigate through the menu.  LG support told me there s nothing they can do. I tried to disconnect the tv and reconnect it, but it s the same issue.

 

Is there a way to hard reset it ? I can t even check the version of the firmware, the only thing working is channel up/down, and the volume (but once again, doesnt display on the screen)

 

thanks for your help

 

regards

 

K.

      Between September 6-10, LG showcased its diverse range of AI-powered home solutions, opening a new chapter of intelligent home living at its IFA 2024 booth. Under the theme of Experience, Affectionate Intelligence (AI) Home, the company presented its unique, AI-inspired vision of future living to visitors from around the world.

      Designed in collaboration with Korean science fiction author Kim Cho-yeop, the expansive booth featured diverse experience zones curated to demonstrate how the company’s AI can be embedded into home life to elevate lifestyles in intelligent and distinctive ways.

      Upon entering Hall 18 of Messe Berlin, visitors were greeted by the AI Home Gate, a massive LED media wall displaying the journey of LG AI, from the birth of LG’s AI Agent, FURON, to how it communicates with the world and enriches daily life.
      After gaining a solid understanding of what Affectionate Intelligence is all about, visitors could explore how it makes everyday life more simple and convenient. Divided into several distinct lifestyle spaces, LG’s booth showcased how natural conversations with
      link hidden, please login to view, can help manage every aspect of daily routines.
      The first lifestyle space, “Second Youth Home,” showcased a new and more active lifestyle for retirees. The digital signage on the wall visualized how ThinQ ON customizes and takes care of home appliances depending on the user. For example, after recognizing certain phrases like “tennis lesson” on the user’s calendar, ThinQ ON automatically sets the washer and dryer to its “Activewear course” via Smart Pairing.

      , employs AI DD technology to intelligently minimize water and energy usage based on each load. It also features Easy Control technology, which automatically selects cycles according to usage patterns and user preferences for maximum convenience.

      The second lifestyle space, named “Smart Green Home,” showcased the ideal abode for families passionate about the environment and energy conservation. Among the many power-saving solutions on display, LG’s AI-enhanced Energy Storage System (ESS) analyzes energy usage patterns and weather forecasts to adjust its mode according to various conditions. Another highlight was the . With these devices – both inside and outside the home, connected to ThinQ ON – LG AI optimizes household energy usage in real-time and reduces energy bills by intelligently managing the power consumption of every connected device.

      The next lifestyle space was the “Affectionate Home,” designed with children and pets in mind. It featured the company’s Self-Driving AI Home Hub, which can move freely around the home and interact with children through conversation. Its multi-modal sensing combines voice, sound and image recognition to change its expression according to various emotions, allowing it to respond to different situations with appropriate etiquette. The hub can move from room to room and control connected appliances and IoT devices, constantly making sure the environment is optimized for the little ones.

      Not just a hub for home appliances, LG AI is an Affectionate Intelligence storyteller that boasts a deep level of emotional depth and understanding, enabling it to communicate and interact with users effectively. Through generative AI, the Self-Driving AI Home Hub can develop stories based on images drawn by the user, ensuring a unique bedtime story every night.

      The next room demonstrated how LG appliances optimize the environment for pets and their owners. Once temperature and humidity sensors detect indoor air conditions, the LG DUALCOOL air conditioner can achieve the perfect temperature with airflow customized to suit the environment and personal preferences.
      This zone also featured the AeroCat, a purifier designed specifically for cats. As every cat owner knows, cats love to sleep on devices and appliances. With this in mind, LG AeroCat can detect when a pet sits on top of it, stopping operation to provide a quiet place for a nap. And since weight can be an important indicator of heath, the AeroCat’s built-in weight sensor tracks the pet’s weight and alerts owners of any unusual changes via the ThinQ app.

      “Delightful Home,” the final lifestyle space on display, presented a perfect setting for inviting and entertaining family and friends through a shared love of food. This zone highlighted LG AI’s ability to make cooking easier and quicker, with ThinQ ON providing menu recommendations and step-by-step instructions for numerous delicious dishes. Visitors could even learn some new skills by watching the “AI Talking Cooking Show,” a live cooking demonstration by chef Kristof Mulack, a culinary master who knows the best ways to customize LG’s AI appliances.

      To let visitors focus on the technology that makes all these lifestyle spaces possible, the company also set up the “LG Affectionate Intelligence” zone. This area effectively illustrated the connectivity and expandability of the Matter-certified LG ThinQ ON, engineered to help users manage their entire smart home with a single device.

      LG also shined a light on its AI legacy with a special “AI to the Core” space. Using a transparent OLED display, the company explained how its Core Tech has evolved into LG AI core tech. This lineup includes revolutionary AI DD and AI DUAL Inverter, both of which employ AI to enhance performance and deliver more precise control, resulting in new and improved levels of customer care and user experiences.

      The final zone by LG was none other than the “Sustainability Lounge,” which provided visitors with an overview of the company’s latest efforts to promote sustainable living. Here, visitors could relax while learning more about LG’s ESG activities, including its use of recycled plastics in select products.

      LG’s booth at IFA 2024 successfully delivered an insightful window into the LG AI Home. Stay tuned to to explore how LG AI can enrich daily life in the new era of AI.

      Kinetic LED signage has transformed how viewers interact with content, emerging as a new method of visual storytelling. Recent technological advancements have forged the way for the brilliance of traditional LEDs to come together with kinetic art technology, creating three-dimensional (3D) displays that exude vibrant colors and dynamic sounds for an enhanced visual experience.

      Kinetic LED signage has become a standout choice for artistic exhibits in public spaces, adding dynamic movement to museums, hotel lobbies and galleries. By displaying animated patterns that seem to emerge from the screen, this innovative signage solution adds a sense of realism to the space that conventional displays cannot replicate. When combined with vivid colors and sound effects, it seamlessly integrates into a wide array of spaces, effectively showcasing diverse content from compelling advertisements to stunning works of art.

      The Sangsang Platform, a cultural complex in South Korea remodeled from an old granary to host various cultural activities, features the gigantic LG Kinetic LED façade as a breathtaking centerpiece. In addition to mesmerizing visitors, the signage solution heightens the ambiance and effectively modernizes the space with dazzling media art displays. Renowned for its size and cutting-edge technology, the LG Kinetic LED signage immerses audiences with its dynamic presence.

      Measuring a massive 3 meters wide by 5 meters long and powered by 240 engine motors, images in the LG Kinetic LED signage come alive in vivid detail with the support of High Dynamic Range (HDR). By synchronizing with 240 LED modules that move delicately back and forth up to 300mm, HDR defies the challenges of traditional flat signage to create 3D content, enhancing the sense of immersion and transforming kinetic motion into a work of art. In addition, with customized digital media and sound, the signage delivers realistic audio and motion for an unforgettable sensory experience.

      From lobbies to shopping malls to public squares, the LG kinetic LED signage creates an impactful visual effect in indoor spaces.

      Hi all,
      I'm wondering how you can get into the service menu (In Start) on an old LG Smart TV (42LB630V) running WebOS 1.4.  I have a Samsung Galaxy S6 (SM-G920F) with a IR blaster, I have tried sending '0x04FB 0xFB04' to I which should be IR code to enter the menu, but that doesn't work.
      I have also tried entering it with the SSAP-Web, but I get:
      error: 500 Application error {"errorCode":-101,"returnValue":false,"errorText":"\"com.webos.app.factorywin\" was not found OR Unsupported Application Type" The SAPP-Web app does works though, because the TV does respond to Get info
      { "returnValue": true, "product_name": "webOS", "model_name": "HE_DTV_WT1M_AFAAABAA", "sw_type": "FIRMWARE", "major_ver": "05", "minor_ver": "05.90", "country": "omitted", "device_id": "omitted", "auth_flag": "N", "ignore_disable": "N", "eco_info": "01", "config_key": "00", "language_code": "en-GB" } The reason I want to access the menu is because I've enabled DEBUG mode on my TV through the NVM method and I want to enter a root shell trough UART to enable SSH and root access.
      Gaining root access through NVM:

      The youtube app on WebOS has a gear icon that's labeled "settings", used to toggle the speed normally to 1.25x, 1.5x, etc. It stopped working about 3 days ago, when clicking on the gear icon nothing happens. I've hard reset the tv, ive deleted and reinstalled youtube app, tried messing with DNS. nothing works. Seems to be a bug, likely a result of some update in backend, should be trivial to fix. But tried calling LG about it and went nowhere with their help desk.
