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.

      Factory Reset, Remote Won't Work, Stuck on Press the OK button(wheel) on your remote (55NANO81ANA)
      By David Daul
      My magic remote and my Roku remote stopped working for turning off power so I performed a factory reset after troubleshooting to get the remote working.  I am now stuck at the 1st screen of the Factory Reset which says "Press the OK Button(wheel) on your remote."  Well... this really stinks because the remote doesn't work!!!  I have tried a USB mouse, a new magic remote, other LG Remotes with no luck.  I have also tried using the button on the bottom of the tv.  And, I contacted support which was just an exercise in redoing everything I had already tried... No Luck!!
      This is a Nano Cell 55NANO81ANA which is basically just a big brick now since I cannot even use any of the inputs.  Does anyone have a trick for getting past this initial screen???
      Thanks for the help.

      LG OLED Presents Work By Sir John Akomfrah to Explore Social and Environmental Issues
      By News Reporter
      At Frieze London 2024, LG OLED and Akomfrah Bring Art and Technology
      Together to Inspire Audiences With a Thought-Provoking Film Installation

      SEOUL, Oct. 11, 2024 — LG Electronics (LG) has once again partnered with the widely respected artist and filmmaker, Sir John Akomfrah, for Frieze London 2024. This collaboration follows LG’s recent support of Akomfrah’s British Pavilion at the 60th International Art Exhibition at La Biennale di Venezia 2024. At Frieze London 2024, LG OLED has invited Akomfrah – an artist and filmmaker known for investigating themes such as memory, post-colonialism, temporality and aesthetics – to present a new video installation at the fair.
      Becoming Wind (2023) is a five-channel video installation that focuses on the intersection of social and environmental issues, looking specifically at the experience of non-binary and trans actors and activists in the context of the climate crisis. A profound meditation on identity formation is framed by an allegorical representation of the Garden of Eden and its disappearance; a montage of footage evoking the abundant richness of past biodiversity is interrupted by glimpses of blazing wildfires, scenes of racial discrimination and a fragmented text, underscoring responsibilities to confront multiple and intersecting crises.
      Powered by the compelling fusion of art and technology, multiple ultra-large LG OLED displays bring Akomfrah’s artistic narratives to life with stunning picture quality on an incredible scale. Notably, LG OLED’s self-lit nature reveals the full, vivid expression of the colors, enriching the depth and realism of the artwork’s multi-sensory elements for a truly immersive experience.
      LG’s commitment to making LG OLED a more sustainable choice closely aligns with Akomfrah’s drive to address climate change, human communities and the plight of migrant diasporas globally. LG OLED TVs incorporate fewer components than LCD TVs due to the absence of a backlight, which results in the 65-inch OLED TV using 60 percent less plastic compared to an LCD TV of the same size. Weighing in at about 20 percent less than an LCD TV of the same screen size, OLED screens also contribute to the reduction of CO2 emissions during transit. In addition, recycled plastic accounts for approximately 20 percent of the plastic used in the manufacturing of all LG TVs, including OLED models. These efforts have culminated in LG OLED TVs receiving environmental product certifications from the UK’s Carbon Trust and Switzerland’s SGS for four consecutive years, underscoring the company’s commitment to sustainability.*
      “I’m truly delighted to be able to bring my artistic vision to life with LG OLED,” said Akomfrah. “Becoming Wind aims to draw viewers into a deep state of contemplation about the intrinsic relationship between nature, humanity and technology through the interplay between sound and visuals. LG OLED’s advanced audiovisual capabilities and technological advancements enhance the sensory elements of the art, seamlessly integrating image, sound and emotion to take audiences on a visually compelling and intellectually stimulating journey.”
      “We are pleased to continue our collaboration with renowned artist Sir John Akomfrah to highlight how LG OLED captivates audiences by enhancing the depth of his thought-provoking artwork,” said Kate Oh, vice president of the Brand Communication Division at LG Home Entertainment Company. “LG OLED remains committed to supporting both artists and audiences who embrace our passion for innovation and positive change. We will continue to empower artists who seek to inspire the world through the intersection of art and technology.
      Visitors to Frieze London 2024 can experience Akomfrah’s artwork Becoming Wind from October 9 to 13 at The Regent’s Park. Visit the

      Help! "Factory Mode: Press INSTOP to go to User mode" is floating across my screen
      By Peter Payne
      I have a LG CX 55 2023 TV and like it. I use it for work, and the dimming-after-1-minite feature is super frustrating. So I used the instructions here (
      link hidden, please login to view) to turn off TPC, GSR and scrolling. It worked well and I was happy. But when the TV turns on a few hours, I've got an ugly window saying "Factory Mode: Press INSTOP to go to User Mode. Press Green Key 7 times to go to User Mode (user remote control.)
      I hate this menu, and I hate having the ability to turn off zoom on a TV I'm using for work or youtube. Can anyone help me solve this issue and get rid of the monitor? I have another LG TV purchase on hold while I determine if there's a way to do this to my satisfaction or not. If they really have messed up LG TVs by making no way to turn off the dimming, I will also find a way to return my current TV to Costco despite having used it for six months. 
      When I tried this before, I learned that the INSTOP button will do a complete factory reset. This is NOT what I want, unless I really have no way to turn off the dimming. In which case I will cancel my other LG monitor purchase and make other plans.

      Issues with LG TV and weird WiFi behaviour
      By Guest
      I recently bought a new router (Unify Dream Router) and after a couple of weeks of struggle, I managed to set it up with my ISP's VDSL connection (FFTC) using a third party modem in bridge mode (NETGEAR D6400).
      Everything seemed to be working fine until I realised I couldn't open the Netflix app on my LG Smart TV. After a bit of investigation, I realised nothing except for YouTube and the Browser was working. Just to make this clear: the WiFi connects fine, I can access all websites through the LG Browser, and I have no issues with YouTube, but nothing else works.
      All the regular streaming apps fail to open and, most importantly, the LG Content Store fails to load. Before I fixed my network, the tv was working fine. If I switch to my phone's hotspot, everything works fine.
      Things that I've tried:
      factory resetting the tv leaving the tv unplugged to delete cache using google's DNS on the TV using a wired connection  Having said so, I am so lost that I would be happy to try anything again.
