webOs TV not functioning well


Joel Rocat

Question

My LG webOS TV was diagnosed with a busted Main Board. The local service center replaced it. After replacing with a new main board some problems were observed;

1. It will shut-off and switch back on a minute after switching on. Sometimes after 2 minutes it will switch-off and back.

2. HDMI1 and HDMI2 ARC is not working anymore.

3. It cannot connect to WIFI anymore also.

Is their a way to make it work again?

      I have LG TV UF6800. TV is working well. The youtube app had worked well until a couple month ago. The yoyube hangs very often after playing advertisement. It also hangs after playing a long video (around 30 min). By "hangs" I mean it is still there, showing the youtube UI, but we cannot play any video. Just black, staying there forever.
      I am using wired network on the TV. 
      I tried updating app, nothing. I googled and tried unpluging power while watching...., no help. BTW the youtube (with the same user) works well on PC and iPad.
      If you think this is not LG's problem, please advise to whom I should contact.

      MX player and jio cinema are commonly used Android apps which offers many free to watch movies. It would be great if that two added in the lg store. Hope it'll be added soon

      Hello,
      We are a company developing streaming apps for our customers. As-to enhance developer / tester / any other teams experience into LG universe, and be able to quickly test any environments we have (dev / staging / production), we'd like to be able to install apps that aren't removed after Developer Mode expires, or aren't visible/listed to the public store.
      We looked upon the idea to extend Developer Mode session with a Crontab with specific accounts for each TV, but some TVs are stopping the Developer Mode when being powered down, so it doesn't seem the most industrialised idea.
      Let me know what we can do to answer that issue !
      Thanks !

      Found multiplex application that use letsencrypt stop working in 30 September 2021 on LG WebOS 3.5. This appear to be wide spread multiplex version of WEBOS.

      Our current app is available on 4K/UHD LG television models running the following system software:
      webOS 3.0 webOS 3.5 webOS 4.0 webOS 5.0 No 720p or 1080p (“full HD”) sets are supported for our current app at this time.
      Note: Due to root certificate limitations with the device OS itself, only webOS 5.0+ devices support secure connections with a personal Plex Media Server. To allow connections to a personal server, devices running earlier webOS versions must be set to Allow Insecure Connections in the TV app settings and the Plex Media Server must be set to Preferred for the Secure Connections preference.

      I've just got a 55NANO80 TV and tried to set it up today. 
      I got through the set up as far as connecting via satellite, cable or aerial.   This stumped me because I don't have any of these, as far as I know!  I just have NOW TV.  So, I pressed exit, thinking that the TV would skip trying to search for channels.   The screen then flashed with vertical black and white lines and then went completely black.  
      I have tried to reset the TV and turn it off and back on.  Nothing shows on the screen, so I cannot press the settings button or anything.  
      Have I been sent a dud TV or have I missed something really obvious?  Any advice would be greatly appreciated.
      Thank you.
      Edit:  I have turned Now TV on and the sound is coming through the television, but I still have no picture.
