Less than a week ago, my 55NANO906NA updated to 04.40.19. Since then, when changing channels, I get some channels with no sound, channels with sound and a black screen, and sometimes just a black screen with no sound. Some channels do show up after +5 seconds. Channels which are not being displayed, do show up after turning off and back on the TV.

None of the mentioned issues were present until the latest firmware version which I mentioned.

I tried to reinstall the update using a USB drive but this only works for updating, not reinstalling the same version.

I rad an article about how to register to the development program to be able to downgrade the firmware and if these issues persist in the following days I will give it try. 

I really don't understand how this can be possible. Is there any channel to report these issues and get them officially fixed?

It's really sad to get all these problems , just after the support period ended. Is it really a coincidence or just a lost of interest towards the older already sold products?

With WebOS it can be worth trying disconnecting the TV from all power, pressing the ON button a couple of times to discharge any capacitors, and leaving it disconnected for 15 minutes. Then connect power and try again. Has fixed weird things for me a couple of times.

      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?

      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?

      Hello, after the last update of WebOS (6.5.0.-24) there is different behavior of returning back to previous input on my TV. When I was watching a Live TV and opened an app like Youtube, after closing it (holding the return button) it used to return to Live TV. The same with HDMI input, when I was playing on Playstation and the opened an app, after closing it it returned back to PS. Now after the update, it always go to the Home Screen when the app is closed. I only found in setting to return to last input when turning the TV on instead of Home Screen, but didn't find the same for the behavior after closing an app. Is there a way to fix it?
      Thanks
