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 🙂

      Hello!
      My parents' LG webOS TV had this issue where their Magic Remote has gone insane and every button thinks it is the mute button.
      I have tried changing the batteries to brand new ones, letting it fully "de-charge" for 10 minutes, de-pairing it, etc. accordingly to the troubleshooting guide. Not even the power button blinks as it should. Oddly enough, the motion cursor works fine.
      I have attached a video to show how it looks.
      Any suggestions to fix this?

      I have owned this tv for a year and pleased with it ... until about a month ago. I now have constant repetitive messages in top right hand corner of screen saying 'Unknown device disconnected' or 'wired network is connected' or wired lan cable is connected' and it's driving me crazy. I have tried the lg live chat technical support and they were not aware of the issue but I've seen the same problem discussed on US forums and here too. Nobody seems to be able to have a solution. I have unplugged all external stuff - Virgin V6 box, Wii, wired internet, etc and it still happens. Help!!

      Updated my LG 55UK6360PTE to version 05.10.10 a few weeks ago. Few days after the update the television has trouble booting up, it gets stuck on the lg logo, then I have to switch the tv off by holding the power logo for a few seconds, then boot it up again only to find it getting stuck on the lg logo again, after repeating this process a few times I am finally able to boot the tv and proceed smoothly until I dare turn it off to face the whole issue all over again. Anyone else witnessed the same problems, is there anyway to downgrade the webos, tried the lgdtvupdater but it doesn't work, I guess it only works for models upto 2017. Correct me if I am wrong

      I want to choose my version .. how to do that ?
    • By necrofobic
      ok so im slowly going insane, just got a new tv and naturally i couldnt keep my fingers off the "update" button.
      before the update the HDR game mode was crisp and bright, after the update it so bloody dim some games are just... way too dark ?
       
      so i tried running a downgrade with lgdtvupdater and got everything to work but when its time to actually download the update to the tv it says that "the update cannot be applied".  everything in the logs are showing ok. but it just wont save to the tv.  it doesnt even start the download, altho i can clearly see in the logs the update is correct and the tv has given the "all clear" to the update server.
       
      am i missing something here ?
