Static on all inputs, menus unaffected - 55UF7600-UJ


guitarist

Question

While watching the TV, lines appeared on the screen with some static. This persisted briefly, then the entire picture went to static. This same static is visible on all inputs, from apps to live TV, HDMI, etc. 

Sound is fine, menus are unaffected. 

So far I have tried power cycling, factory reset, disconnecting all cables, and trying different picture settings, to no avail.  I suspect some kind of hardware issue. Any tips gladly appreciated. 

Edit: I have a replacement EBT63990603 mainboard on order, hopefully that solves it. I see some people have attempted to reflow the solder on the processors to fix these, seems like a dice roll.

      I have a NANO91ANA LG TV connected via HDMI to a Yamaha RX-V677 Receiver. Normally when I turn the TV on it also turns the receiver on and I can control volume via the LG remote, whether it is an app on the TV or from another device connected to my receiver (Apple TV or cable box). Now the receiver is not turning on and ARC audio is not working. I think there may have been a software update the other day, but I'm not sure. However, everything was working properly until last night. The last time this happened it seemed to correct itself (it seems to be kind of sporadic), but this time it did not. I do not know what to do to correct this, but it is a major pain as I'm now having to deal with 4 remotes, plus I can't get sound out of my surround speakers when using an app on the TV.  Any suggestions would be appreciated.

      Hey there,  I have had a  OLED55B6P for ten months and I love it but

      I have a problem all a sudden, just today it starts to show a black screen with fire works every minutes if I don't press a button on the remote.

      I have no eco mode on, no power save modes on, TV firmwire is up to date, and tried turning off on and on the tv.

      anyone know how to fix?

      As the title sort of says, whenever I rename the HDMI inputs on my new TV, they seem to reset at random. Sometime's they've reset when the TV is put on standby mode for several hours. Other times, I've noticed they've reset while the TV is still being used. I always end up renaming them in the morning, and eventually, they've reset themselves back to HDMI 1 (Xbox One X) and HDMI 2 (Elgato Capture). 
      Sometimes, only 1 of the names reset. Other times, they both reset.
      Does anyone have any ideas as to why the names keep resetting? TV off or on, it doesn't seem to matter. Any help would be great!
      Please and thank you!

      hi guys, I have an LG CX65 bought a month ago. it's already happened two times that while I was watching a normal TV channel the fireworks screensaver kicked in. After the first time I did a reset of the TV, but it happened again today. Someone has experienced this issue? If could be useful to know, I have an Xbox series x, a ps5 and a soundbar connected respectively to HDMI port 1, 2 and 3 and the consoles always stays in sleep mode. they works great, no problem at all, and the hdmi cables are brand new.
      the first time the fireworks kicked in while a was watching a news Channel i has only the soundbar and PS4 connected tho.
      I hope you can help me out

      hello
      we just bought the LG OLED 65C1 tv.  on our previous Samsung tv we were able to use a Samsung sound bar connected via hdmi and wireless headphones (that uses a the charging base plugs  into the audio port on the tv and then red and white leads that plug into the charging base )
       
      for some reason we can't get the sound bar and headphones to work at the same time any more?
       
      we have tried plugging sound bar into optical port rather than hdmi and the headphones into audio port but still we can't get them to work at the same time.
      what do I need to do to get both sound bar and headphones to work at the same time??
       
      thanks
