LG CX OLED 55 Crashing

Question

Hello guys and gals,

I am not sure if this question is for here, but i tried reading some posts on the internet and could not find a reasonable explanation or solution to my problem, so here it is.

 

I bought my TV (official model i think is OLED55CX3LA) about 2 weeks ago along with LG Soundbar SN4, connected via optical cabel.

In few words, the setup is as follows:

- Picture mode - Expert (Dark Room) with Gamma set to 2.2 and TruMotion to Natural

- Sound is set to Cinema mode and Optical+Internal TV Speaker

No AI features are turned on and TV is connected to internet via ethernet cable. I have set-up box connected to the TV, a laptop, both with HDMI, and streaming with Serviio over dlna.

Now the issue. On 3rd-4th day the TV started crashing only while watching from the set-up box. The picture will freeze, some times a high pitch noise appears, the TV is unresponsive. This goes on for 10-20 seconds, the TV turns off by itself and after 5 seconds it is turned on. Sometimes it does it once and not again, sometimes there is a day without doing it, sometimes does it constantly one after another unless i change the channel, or change from set-up box to DLNA for example.

I changed HDMI ports, i changed HDMI cables - no effect. I thought it is something in the signal from the set-up box (sometimes it is very low quality, or whatever else), but yesterday same thing happened while watching 2160p movie from DLNA.

You can see what happens here:

The video on my cloud is only 2 minutes, but in reality this went on for about 7-8 minutes until i changed from set-up box to DLNA. Just the video was too big and had to cut it.

 

Thank you!

I was experiencing what sounds like this problem. (C9 with sound bar) It wasn’t happening often and hasn’t occurred since the last firmware update about 10 days ago. Have you updated?

Hello Krishna Kumar,

 

Thank you for the help!Unfortunately my TV does not seem to have TV Sound sync as option(Uploaded picture of the current options). I previously had the soundbar

connected via bluetooth but this had a lot of issues from sound delay perspective(issue with TV crashing was still visible), so i had to connect it via optical cable. Also i would like to still use internal speakers + soundbar as audio.

I also did the pixel refresher procedure 2 (or 3 times, not sure) already.

Also uploaded picture of the current software version - no newer one when i press check for updates.

      Hi there. I have this problem. I had the LG 49U67V turned off and the power cable not connected to the electricity socket for 4 days. Since reconnecting everything I can't connect to the Web. Neither by WiFi or by ethernet cable. The TV seems connected in the settings. But the the speed is practically zero. This is the case with WiFi and with ethernet. 
      No it not the case we're the WiFi disconnects itself and which is solved by disabling the Quick start functionin the settings. 
      What happened?

      Dear Readers,

      I've a strange issue that I've been struggling for a week. I bought an LG43UJ634V UHD TV and an LG LHB645N Home Theater in a Box system.
      I use HDMI ARC to connect the audio from the TV to receiver. LG has an option to chose between PCM or Auto at the Digital output settings.

      If I use the PCM option everything sounds great, but I don't have 5.1, only 2.1.
      And here comes the problem. When I choose Auto, 5.1 is on, sounds great but I have occasional popping noise (like when play something on an old LP player) it happens random, but for example during a film, it is very annoying. It happens with YouTube, Netflix, DLNA streaming, external devices, so the content doesn't matter. I think I've tried everything. I tested it with different HDMI cables, optical cable, but still have the problem. I tested it with a sound bar as well, the problem is the same.
      When I play content from the receiver, there is no problem, the sound is wonderful, no popping. Also, the TVs speakers are okay.

      I don't think it is a hardware issue, because the TV's sound is OK, the home theater's sound is OK, the problem only happens when I want to use the digital output of the TV (either HDMI ARC or Optical) with auto setting.
      I called LG as well, the rep. said the she will pass this info to the technical team.

      Do you have any idea, that it can be solved, or I need to wait for a software update?

      Hello,
      I share audiovisual material (movies and series) with my brother who has an LG 49UK6400PLF and it has us crazy, because some subtitles do reproduce them and others do not. I have already tried internal and external subs and various formats, srt, ass, ssa, sub, and nothing, because some work and others do not.
      I would like to know at least the reason, to try to solve the matter.
      Regards.
