Good afternoon,

I have a 49UB850V-ZD smart TV and has the issues below. Can't understand if its a software issue or components issues:

1. Can't reset using meniu. I can access the meniu, I inserted pin 0000 and if I try to click Confirm it just flashes the button with no success. If I click Cancel then the meniu closes
2. The Live TV channels are not working. There is no issue with the provider. It just not plays any channel
3. If I connect the usb or hard-disk driver to play some movies I can navigate thru folder but I can t play any
4. When I connect to Netflix or youtube I can navigate but if i try to play it does not load.
5. The remote TV does not work anymore -> Only the Power Off/On button
6. I have a magic remote TV for LG and works to navigate with the indicator
7. The button of the TV (under the TV led) works only to open the TV -> the menu does not work anymore
8. In the advanced menu, the Channel settings is not active among other options that are disabled. 
9. When I try to access the LG STORE it says: loading unsuccessful (82) because the hour of the TV is not the correct one. I tryed to change time to something different and also changed location and removed the location. This change did not had any effect 

What do you think? What do I need to do?

Me too! 

I never had issues before with playing 4k videos on Netflix or watching 4K cable chanels worked like a charm.

Now, since two weeks ago, when I try to play a 4k channel, the TV is freezing and all the channels are gone.  

If I tried to load an UHD movie on Netflx it stops around 20%.

I have no idea what was causing this. (I don't remember to have auto update feature activated)

 

Did you guys managed to fix it? How?

Hi. Did you find any solution? Have you tried contacting Lg support in Romania? I did that, they said this issue has never been reported. Maybe if they see that this problem is identical, reported in the same time period, on the same TV model, they will do something...

Hi, yes for sure.

I've contacted them initially, but they said it might be an issue from the cable company.

However a guy from the cable company came and changed the ci+ card, but the issue is still there.

Then, I've contacted back LG support and they directed me to their official service representative ESD ROM.

Now, I am waiting for a cost estimation, but I'd guess this will be huge :)

They told me the same...

But the problem seems to be software only. I assumed that the latest software version has some problems. Unfortunately, there is no downgrade procedure, so you can't do much more. Even overwriting the new version is impossible!

Can you please keep me updated on the cost estimate from ESD Rom? We can also discuss in private, if you agree.

I still recommend you open up your TV and make a picture of your main board. Look it up on the internet and you can buy it for 400-500 lei. Just plug and play. It worked for me, it will work for you as well.

The issue comes from the HDMI connector. Sometimes it shortcircuits the board in a way that some functions stop working.

Have you received a cost estimate from EsdRom? Thanks

well, not really - they told me to bring the TV in one of their location for a technical expertise - 80 lei.

but another independent service told me that the main board need to replaced - 650 lei. 

Did not took any action yet.

      LG 65QNED92AUA issues/Bluetooth connection dropping
      By mesplint
      I have a LG 65QNED92AUA tv that has issues with the Bluetooth connection dropping off when connected to my earbuds. I believe the issue to be software related. LG has sent 2 technicians out to repair and the first technician changed the main board and Bluetooth transmitter which did not resolve the issue.
      There are similar issues with Bluetooth Connection from others.
      Since hardware replacement didn’t help and this is a known software-pattern issue, I would like push LG to specifically address it at the firmware/webOS level. I am unable to escalate to their software team and check if there’s a known patch or beta firmware for the QNED92 line. 
      For some reason this line of questioning is not available with in LG customer service.
       Please help!

      Prime Video unable to update/install on LG TV OLED65G36LA WebOs 8.20.0-710
      By Juicycarrot
      Hi there,
       
      I have an LG smart TV OLED65G36LA (LG OS v03.20.17, webOS TV version 8.20.0-710) , and the Prime Video App was no longer able to update (from Dec 2025) and therefore could no longer be used.
      I have tried uninstalling the app and re-installing, and that was unable to work, so then applied a full reset on the LG TV and so had to reinstall all of my other apps (Apple TV, Netflix, etc etc) which all successfully downloaded so confirmed network connections and setup are all confirmed working.
      When I try to download the Prime Video app, it remains stuck on the download screen and is unable to update.
      Thanks

      LG C5 TV/Denon ARC/CEC issues
      By KKTPA
      I have a Denon AVR hooked up to the HDMI 2 input on my LG tv. When I initially set it up, I was able to control the volume of the Denon receiver by using the LG remote. I enabled CEC Simplink and eARC on the TV and this allowed me to not only use the volume but also turn the receiver on and off automatically with the TV. Recently, my LG tv installed a software update and ever since that point, the TV reverts to TV Audio instead of HDMI 2 every time I turn the TV off and back on again. I then have to change the sound setting to HDMI and the volume control works perfectly. 

      Any tips? I already tried unplugging everything including the HDMI cables, turning CEC and eARK off and back on again, and reverting to all original settings but nothing seems to work.
      My Denon receiver does not have eARC support, not sure if that matters but I'd love to know the best way to set it up to control volume through one remote.

      DNS Resolver issues after Update
      By Daniel Buxton
      Hi,
      Since updating our OLED65G2PSA to 23.20.56, we experience sprodadic issues with the network where any app requiring network access shows the generic 'no network access' message.
      I have found that when this does happen, I can still PING the TV and connect to IP based web pages.  To fix I can either power cycle the TV or I can go into network settings and toggle off/on 'Set automatically' which must just be triggering something in the underlying OS to reload its DNS service.
      Setting a static IP makes no difference, setting a static DNS server makes no difference - it is clearly a software issue.  We have had a TV repair company come and replace the boards, which worked right up untill updating to 23.20.56 and beyond.
       
      Has anyone else experienced this, does anyone have a solution ?

      [On the Job] A Day With Charles Lonergan, Manufacturing Director at LG’s Tennessee Smart Factory
      By News Reporter
      Tucked in the heart of Tennessee, LG’s smart factory is a modern marvel – designed for speed, precision and innovation. At the helm is Charles Lonergan, Manufacturing Director, whose steady leadership keeps this high-tech operation running smoothly. We spent a day with Charles to learn more about his role, the technology behind the factory and what it takes to lead one of LG’s most advanced production sites.

      From Inspection to Innovation: A Day in the Life
      Charles oversees the production of LG’s front load washers, top load washers, dryers and the sleek WashTower. His day starts the same way, every day – with a walk across the factory floor.
      “Each day starts with a walk-through,” he says. “We check equipment, review workflow and make sure everything’s set to hit our production targets.” Mornings are all about quality. Charles and his team review every production line to ensure each unit meets LG’s standards. As the day goes on, meetings shift focus to what’s ahead: upcoming products, refining processes and tracking performance metrics. “No two days are exactly the same,” Charles says. “But the goal always is – run better, solve faster and never stop improving.”
      A Fully Integrated Manufacturing Ecosystem
      One of the things that makes this plant unique is how much happens under one roof. From injection molding and metal stamping to painting and packaging, nearly every part of the process is handled on-site.

      “This level of vertical integration gives us complete control over quality and timing,” Charles explains. Take the unmanned logistics warehouse, for example – it stores large, molded components and uses smart trolleys to move them through the facility. The system tracks inventory, controls curing time and ensures parts arrive at the next station right when they’re needed.
      High-Tech Meets Hands-On Training
      With a factory powered by automation – Automated Guided Vehicles (AGVs), Autonomous Mobile Robots (AMRs) and AI-based inspection tools – keeping everything running smoothly takes serious know-how.

      “To support all this tech, we built hands-on training programs from the ground up,” Charles says. “That’s been key to stabilizing operations and helping our team work confidently with advanced systems.” Ongoing training is a must, especially in an industry where technology keeps evolving. The Tennessee team is making sure its skills evolve just as quickly.
      Quality Built Into Every Step
      At this factory, quality isn’t a final check – it’s built into every phase. The team uses a three-stage process: raw material checks, 100 percent inspection of each unit for function and appearance, and final sampling before shipment. AI vision systems help verify precise fastening. Multi-camera setups monitor each unit’s key checkpoints. These technologies help catch errors early, before they become issues down the line.
      Innovation From Day One
      This factory was built to be smart from the start. That gave Charles and his team the chance to design workflows around automation and robotics – rather than adding them later. Robots handle complex or physically demanding tasks. AGVs and AMRs navigate the space using QR codes and LiDAR. Workers, meanwhile, focus on higher-value responsibilities, making the whole operation more efficient and safer. “Robotics aren’t just for show,” says Charles. “They’re woven into our everyday workflow.”

      Pride in Progress: From Construction to High-Volume Production
      Charles has been with the Tennessee plant since day one – literally.
      “I’ve been here since before the first wall went up,” he says. “Now we’re producing over 300 units per hour. That’s something to be proud of.” The journey hasn’t always been easy – ramping up operations and fine-tuning quality took time. But every challenge helped the team grow stronger and more agile. “Continuous improvement is just how we operate,” Charles says. “We’re always thinking about what’s next.”
      Work, Life and Balance
      Leadership at this level is demanding – but Charles makes it a point to protect his time, both at work and at home. “I rely on daily planning, time-blocking and a strong support system,” he says. “Time with family is just as important as hitting production goals. You can’t give your best at work if things aren’t balanced outside of it.”
      Looking Ahead
      Charles’s story is part of a bigger picture – LG’s commitment to smarter, more sustainable manufacturing. With his eye on the future and a passion for progress, Charles is helping lead LG’s Tennessee Smart Factory into a new era of intelligent production.
