Since my lg-oled65c9pla auto-updated to WebOS 5.5, there is a new bug.
The TV is connected to my Cambridge Audio Evo 75 amplifier over ARC - on powering the TV, it has always started up the amp, and switched it to use audio, instead of the appalling TV speakers. The whole setup has worked flawlessly for 5 years, but since WebOS 5.5, the amplifier starts, but is left in a muted state, and using the un-mute or volume controls on the TV remote makes no difference to turning on audio. The only way to get audio to play though my amp a speakers is to turn the amp's volume dial or press a volume button on the a amp's remote - this then unmutes the TV and audio is back.
There is no setting I can find in the TV that relates to whether the ARC channel starts muted or not...
No software has changed in my amp. This is an annoying new bug in the TV software, I assume down to some CEC changes.

i am having an issue with my LG OLED77C2 tv that started happening (i believe) once i have updated from web24 to 25. It seems like whenever the tv is displaying a source from any of my four HDMI inputs, while i am watching the screen goes black randomly for a few seconds and it loses audio as well during the black screen. Once this happens the audio usually comes back as soon as the image does, however not always. The audio might dissapear completely. In order to fix that i might need to power cycle the tv or unplug the hdmi input out, wait a little and then plug back in. Moreover, sometimes when the black screen flash happens it cripples most of my native apps on the tv. So if i switch to netflix or youtube right after the black screen flash, both apps populate normally all the video/film options in the main menu but when i try to actually play any of the video/films, they dont play and it is throwing an error. These black flashes never happen when i am watching netflix or youtube. Only when using my hdmi inputs. ive changed brand new high quality cables but that did not fix my issue. For the xbox i was already suing an ultra hish speed 2.1 hdmi cable but ive re placed that as well with a brand new one. ive also changed the tvs main board to a brand new and it still happening. Once the dealer changed the board, the tv was behaving normally without the issue. However after a few days i updated the tv to the latest firmware and this started happening. what do i do?
FYI: I tried EVERY SINGLE option to troubleshoot the issue. Disabled VRR, AMD Freesync, ALLM, HDMI Deep Colour, SIMPLINK, I basically set my tv to display video and audio in the most archaic way just to troubleshoot. Still doing it. I am using an xbox series x on input 1 and a mag520 box on input 3. Does it on both sources. Moreover, in case this helps whenever this happens while on the xbox the Dolby vision/HDR logo appears on the top right right after the video comes back once the black screen is over depending on what settings i have the xbox on. Also swapped to different inputs. Still doing it

Hi!
I own a OLED65C8PUA 65-Inch 4K Ultra HD Smart OLED TV and it seems to be suddenly freezing when a commercial starts on a LG channel. I've unplugged the TV, hold down the start button, restarted to clean out the cache. I even restarted the whole system where it deletes most of the apps and all your picture and internet settings. Still getting this freeze during ADS between the LG channel presentations (be it the 80's, 90's, Love Boat channels, etc.) Anyone else have this problem? I'm kind of at a loss of what to do next.

In mid-October, London once again became the global epicenter of artistic inspiration as Frieze London 2025 filled the city with creative energy and cultural dialogue. Joining the celebrations, LG showcased its passion for art and innovation through a stunning presentation that brought together the visionary legacy of Korean modern art and the cutting-edge power of LG OLED technology.
At Frieze London 2025, LG presented the renowned abstract ink paintings of Se Ok Suh (1929 -2020), a pioneer of modern Korean ink abstraction, digitally reimagined by his sons – renowned contemporary artist Do Ho Suh and visionary architect Eul Ho Suh.

By combining traditional art forms with LG’s state-of-the-art OLED TVs, the Suh family transformed Se Ok’s iconic ink paintings into a dynamic, immersive digital experience. Do Ho reimagined the beauty and radical inventiveness of Se Ok’s “People” series on the OLED screens, animating marks that explore the philosophical relationship between humanity and infinite space.

LG SIGNATURE OLED T transparent TV and LG OLED evo TVs served as the canvas for this immersive reimagining, presenting overlapping video animations of Se Ok’s black ink abstractions. Each brushstroke came alive with movement and depth, enhanced by the OLED’s perfect contrast and luminous clarity. Viewers were drawn into a rhythmic interplay of form and light – a seamless fusion of art and technology.
Eul Ho, who designed and curated the exhibition space, created an environment that reflected both the fluid motion of the artworks and the elegant transparency of LG’s OLED displays. The installation invited visitors to experience art not as something observed, but as something felt – a living, breathing interaction between tradition and innovation.

Extending beyond Frieze London, this exceptional exhibition continued at the Korean Cultural Centre UK (KCCUK), where Se Ok’s works – reinterpreted by his sons – were displayed on LG’s 83-inch OLED TV. This collaboration between LG and KCCUK formed part of a broader mission to celebrate Korean cultural heritage and bring Se Ok’s visionary artistry to a wider audience. Alongside the digital presentation, a documentary offered deeper insight into Se Ok’s creative journey and the philosophical ideas that shaped his practice.

Question
solidblue
My TV has stopped recognising the live TV signal from the aerial since the OS updated recently. The aerial works fine when plugged into other devices but when plugged into the TV it doesn’t recognise the signal for days on end. When this happens, it will no longer allow me to do a signal test via the settings (the option is greyed out). I’m guessing it’s either a) a problem with the input (hardware) or; b) a problem with the OS (software).
