I have a 65 Inch LG OLED evo AI C4 4K Smart TV 2024 - Model OLED65C4PUA.ACC. here have been a many weird things happening. This is one of them:
I have 2 HDMI 2.1 cables attached to a Rogers Internet TV unit (HDMI 4) and the other 2.1 cable plugged into an XBOX Series X (HDMI 3). If the TV is on an HDMI 4 is active, and I turn on the XBOX (HDMI 3), the TV begins to swtich back and forth constantly and never ends until I turn off the TV. It will automatically switch itself from HDMI 4 to 3, then 3 to 4, then back to 3 again non-stop.
If I power off the XBOX, this behaivor stops.
Would anyone know why this does that? Is this a software or hardware problem? I tried to describe this to LG Support but they had no answers.

I'm not getting any audio from the apps via the HDMI via ARC connection to my receiver. This occurred two weeks ago and was unable to resolve it, but ironically there was new firmware released that same day for my B6 (3/31/17) and this fixed the issue. However, now I again can't get it working after a TV reset and tinkering with the audio settings again. I tried to load the firmware again, but it appears this is not possible to forceable load the same firmware.

Hi,
I've recently purchased a WebOS TV UK6400PVC and magic remote came with it. The software version is 4.10.30.
The buttons work fine but for some reason, I can't get the cursor to appear on screen.
Appreciate the help. Thanks

On my LG 60SJ850T, Watching Horizon from AppleTV streaming service. Western with some scenes with Apache language being spoken. No subtitles appearing. When CC is on, see “foreign language being spoken”. When viewed on iPhone, there are subtitles. Have tried same movie using chrome cast TV, and casting from iPhone to Apple TV device. Never get subtitles. Verified subtitles work when I stream to same chromecast TV connected to a different TV.
reset LG TV to factory settings after trying all available CC and subtitle settings on TV. Still no subtitles.

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?
