Latest software update broke HDMI on my LG OLED G2?

Up until a few days ago my TV and AVR have been working perfectly since I bought it.
Zero hassles with HDMI and connectivity.

Then I was prompted to update to the latest software version which I did and now often when I switch HDMI (running on 1) it picks up the device name, CEC works but I get “No Signal”… and then nothing.
Just stays on “No Signal”. It is almost as if some HDMI handshake breaks and now the driver is in a broken state.

I’ve found that if I hard power off and power on the device sometimes works but I don’t want to do that every time especially since it’s hard to get to the power.
This really strikes me as a software issue with the latest update as absolutely nothing else has changed in my setup.

I’ve tried:

  • Different HDMI cables (high quality)
  • Deep colour settings
  • Reset the TV to factory default
  • Different HDMI ports

TV

  • Model: OLED65G26LA / OLED65G26LA.HFBQLWK
  • WebOS TV Version: 8.3.0.2301
  • Software Version: 13.30.56

AVR & Devices

  • Marantz SR5015
  • Nvidia Shield Pro
  • PS5
     

The setup is the conventional AVR installation as shown in the attached file

Has anyone else experienced this? 

Is it possible to revert the software update?

I have experienced the same issue with Denon AVR3400H.  I’ve seen other posts along this line and hope there is a patch by LG to remediate!   It’s a large inconvenience as base LG oled sound is not terrific.

      Sky News stopped working after the webOS update
      By Roy Brown
      webOS updated, I think to 2023, on my C2 a couple of days ago. Since then the News option on the Sky News app no longer works, instead timing out. The Weather and Climate options still work, though.
      I have deleted and reloaded the Sky News app, but the problem remains.
      Does anybody have any suggestions of what I might try to get this working again, or is this something for LG, or Sky, to fix?

      Enhancing Art Through Technology: LG OLED TVs Illuminate Masterpieces at Manila’s National Museum of Fine Arts
      By News Reporter
      As an avid supporter of the arts and culture, LG Electronics is committed to enhancing life by integrating its groundbreaking technologies with some of the world’s most exquisite art pieces. By providing artists and gallery curators with the finest LG OLED TVs, considered by many as the ultimate digital canvas, LG enables a captivating and inspiring multi-sensory experience.

      In the Philippines, LG partnered with the National Museum of Fine Arts in Manila to celebrate the 140th anniversary of Spoliarium, an iconic masterpiece by renowned Filipino painter Juan Luna. Coinciding with National Heritage Month, LG Philippines donated various products, including LG OLED TVs, to the museum to foster a deeper appreciation for the arts and enhance public access to the nation’s rich cultural heritage.

      On May 27, a total of 118 local journalists gathered in the esteemed museum’s Old Senate Hall of the Philippines to witness the latest advancements in home entertainment, including the newest LG OLED evo TVs (G4 and C4 series). Powered by LG’s α (Alpha) 11 AI processor, which offers four times the performance of its predecessor, LG OLED evo TVs provides personalized experiences tailored to user preferences and viewing habits.

      Throughout the elegant rooms of the National Museum of Fine Arts, various LG home entertainment products were on display, allowing visitors to see firsthand how LG brings out the best image quality with its deep blacks and vibrant colors.

      The event also featured the LG Objet Collection Posé, a Lifestyle Screen designed to provide new interior design freedom for décor enthusiasts. With its angular, minimalist design and flexible installation options, Posé blends seamlessly into practically any space with exceptional ease. It even boasts LG’s immersive Gallery mode, which displays works of art or photos on its self-lit digital canvas, transforming any space into a sophisticated gallery.

      In addition to the OLED-infused devices, LG showcased its QNED TVs, which offer enhanced contrast, brightness levels and detailed picture quality for exceptional viewing from every angle. For those looking to create the home theater of their dreams, LG soundbars were strategically placed around the museum to elevate the viewing experience with incredibly immersive surround sound.

      This event highlighted LG’s full commitment to fusing technology with timeless art to unlock more engaging and impactful cultural experiences. Aligned with its Life’s Good promise, LG will continue to support initiatives that spark creativity, promote cultural exchanges and enhance the appreciation of arts and culture through smart life solutions built for all.

      HDMI Arc stopped working.
      By Joe Wong
      My LG 50 inch Model: 50NANO75UPA HDMI Arc stopped working with my Vizio soundbar. It worked very well when I first connected it until this morning. I purchased an extended warranty, but is there a known solution before I send out for help? It is definitely the LG Tv, and not the soundbar because I used to have a Samsung soundbar, which worked only for about a week before the HDMI Arc stopped working and I switched over to the Optical. Now even the Optical does not work That's why I bought a Vizio.

      web os version 87 update to 89
      By Burkey
      hi all. new to this but really stumped!!! i live in ontario canada and have been using cogeco cable for internet and tv. it got way too expensive so i cancelled both and switched to bell 3.0 which is at least 3 times faster and we have no tv package, so we are just streaming everything for 1/3 the price!!!!!  i signed up for a couple of sports sites, tsn and sportsnet + so i can watch hockey playoffs and other sports.  tsn works just fine on the tv.  however, sportsnet + says that i have to have web os version 89 or higher.  i found my tv, which is a 2023 version, is only version 87!!! i chatted with tech support and they were no help.  anybody got any ideas as to what i can do for this???  no auto software updates for it and nothing on the lg app store.  quite confused how a 2023 model is not up to date, or sportsnet+ is that far ahead and not backward compatible>>>
      thanks to anybody that answers.
