TV OLED LG 65C3 randomly shutdown

[dinoc]

Hi everyone,

 

Since the last OS SW update for webOS 23.2050 for my OLED LG TV 65C3 I have noticed a weird problem where the TV randomly shuts down by itself while watching TV, Netflix, YouTube … I couldn’t find a pattern when and how this happens it seems to behave like this randomly. I

t’s like.a SW crash behaviour memory leak or something (just an assumption).

I mention this is not the energy saving auto power off feature.

Have you guys encountered such issue?

Hello Dinoc, I am also a user of a LG C3 65OLEDC3. I have recently upgraded to 23.20.50 like you. Everything is working fine. Except that sometimes there are some short interruptions on different streaming platforms like Netflix or Fubo or even Youtube. BUT the TV is not rebooting. The worse is that recently I got a kind of 30 secondes retro feedback on Netflix and Apple TV (I mean, I was looking at the TV when suddenly it went back to 1mn ago in a series). No SW crash, no rebbot ... Could i be a fiber issue ?

Yes, this sounds more like a networking/streaming issue.

Information about the reasons for turning off the TV (due to problems with the equipment or a normal shutdown with the remote control) is stored in the logs of the TV service menu. You can look there and evaluate what causes the shutdown. The decoding of the codes is here:

Hi, Vladimir,

 

So I need a special remote to enter the service menu? I only have the LG Magic remote (I don't see any in-start button there).

Hello dinoc!

You can use your TV browser or app for Windows - Color Control to open service menu.

Hello I am having simmilar issue with LG Oled 65 C4, I bought it two days ago, and it just freezes and restarts tv after about 10 min of watching Netflix or MAX ( some times after 20 min, sometimes after 6-7 min )

did you resolve this issue ? Can it be fixed?

Hi BozaB, did you also upgrade to a recent webOS version just after the C4 installation ? You can check that in the setting (wheel) menu from the magic remote. You can also see if you have notifications to ask you some actions (like updates).  I suggest that you update to the latest version that you can (for the c3, this is the 23.20.50). I don’t have it for the C4 … Also, I only have 2 devices connected to my LG Tv (a box and a sound system). I suggest that you disconnect some of these devices (one by one) and check if you still have the issue.

I haven't resolved the issue, the local service support asked me to reset it to default and monitor, did it but it does the same thing, randomly resets itself while watching Netflix, Max or Youtube.

I tried the service menu but I couldn't understand it was not able to see the reason for reset.

Yes I updated to latest update, unfortunately after few days of trying everything I can think off, I called customer support, and it turned out if you believe it or not, I bought new tv with factory broken motherboard.. Thank you for the help.

I contacted the local LG service center and they changed the motherboard for the TV (under warranty), hopefully the new one will work fine.
