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!

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, did you ever resolve this problem? I’m having the same exact issue. I’ve read it might be related to overheating due to the wifi cheap. Curious to know if you ever figured out your issue or just ended up getting it repaired or replaced?

Hi,

 

i tried everything but nothing helped. I called local LG representative and they sent couple of guys with fancy looking remote. They were able to enter some hidden menus and troubleshooting options, which showed error code related to what they said communication issue between motherboard and processor. 
so they took the TV. After a few weeks they returned it with replaced motherboard and no issues since.

      Hey, I have a LG OLED65CX TV (latest WebOS) and  some photos from my Synology NAS are not loading, only in thumbnails like this:
       
      Most photos work perfectly but some not. They are scans from a photobook and then individually cut in Zoner but that shouldn't matter right? Here are properties of one of the photos

      I really don't know the reason my TV and it makes me really mad since it took a long time co scan these.
      Weird thing is I also scanned other positive film photos and they work great on TV.
      Do you know what might be the problem?

      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?
