Thanks for reply. I want to try my chance with local LG service.  I will inform you if they will fix my problem.  Thanks again.

copy / paste from my reply on the firmware topic :

ever since i updated to the last fw, my tv turned into a total piece of trash ,

although it was not working so well before the update but after that, it is completely useless i can tell you . 

wondering how much longer we have to wait for a real fix ...

been facing this issue since may 2018 and it get worse and worse with  any new update ...

plz fully  test fw  before u turn our tvs into a useless pos . 

49sj800v .

I have the same exact issue since the last update, i tried to contact with support but they told me that i should send it to local LG service. Its obviously a firmware issue and there is no way to downgrade, my tv is literally not useable right now.  49SJ800V on 05.80.15 fw version. I found a fix by myself but its temporary. If you disable Wi-Fi  or Ethernet the problem goes away but you can't use any of the online features. Hope they fix this ASAP.

same issue wifi and remote control stop responding randomly since 05.80.15, model 43uj750v.

the TV is now unusable outside manual control located on the bottom of the screen.

revert to factory settings didn't help much, after a couple of days the TV become unusable again.

LG software Q&A is disgusting.

I called the LG local service and made a servise request. When they came home they only opened the back of the television and clean and fixed the sockets. It means there was a socket cable that was wrapped. They opened it and flattened it. My problem resolved my TV is working properly and they didn't make any FW downgrade. My firmvire version is 05.80.15 Ithink you need to call your local LG service and tell them my story 🙂

      OLED65CXAUA lg tv. software update - tv is now acting very strange
      By Glamma2311
      My tv is acting strangely after there was a software update (sometime between April 10-15,2024)
      randomly turning off and on -- many times within a few minutes remote works some of the time or only certain buttons goes to a colored screen i.e. purple, yellow, light blue with no image just color sudden annoying continuous, high pitch sound like an alarm Checked and reset the cable box and called cable company. 
      Unplugged and plugged tv back in.
      Change the HDMI input
      It is becoming very frustrating.

      Latest software update broke HDMI on my LG OLED G2?
      By OliverRC
      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?

      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?

      all channels and transponders are getting deleated by simply exporting and importing the channellist (LG OLED G2 newest firmware)
      By SailorMoon
      Hello,
      I have a problem with my new LG OLED G2 newest version 4 firmware.
      I tried sorting my satellite channels with chansort programm from github, because sorting them with the tv remote is a pain.
      When I try to sort them with the remote and have selected about 10 or more channels all the selected channels get suddenly getting deselected, so I can only select up to 10 at a time  to 
      sort them -> must be some kind of firmwarebug? 
      After exporting the channellist to a usb stick then editing it with chansort an importing it back into the tv all my channels are gone, all transponderns are deleted.
      First I thought it was a charsort problem but all channels and transponders get also deleted when I simply export them to a usb drive an import them back, without editing the file at all.
      Does someone know how to fix this problem? 
      And yes I´ve done multiple factory resets -> did not fix any of this behaviour.
      I also discoverd another bug the deletes all channels, because I needed to reboot the tv I searched for a reboot option in the tvs menu, but there is no reboot option.
      To do a full reboot (except from forcing it through cutting the tvs power) you can deselect the privicy agreements, after that the tv reboots, but then all channels are gone too.
