Bricked LG TV after automatic update 43UM7199PLB 27.10.2022


Ioan Alexandru

Question

I have accepted to update the TV firmware after being requeste many times by the menu. Big mistake!
After the update was finished the screen remains black, but the LCD screen is back lit so I can see it's started.
The magic remote has the microphone function and I can still search using the voice for youtube videos and the sound is playing.
o the TV is functional just I have a black screen

I tried after to run the update from USB after manually downloading this update: SW File(Version 05.30.11)
from 

link hidden, please login to view

No menu is showing, screen is still black
A folder was create by the TV and it contains a file
D:\LG Smart TV\TN\INFO

With this content:
{"INFO":"{ \"core_os_release\": \"4.9.7-11\", \"returnValue\": true }{ \"device_name\": \"k5lp\", \"returnValue\": true }"}

Any solution for me? Do I have to change the TV motherboard? I want a cheaper solution, not paying for a new motherboard in service.

My TV too.
After the update my screen remains black. Back light is on and the TV is working. I can start Netflix, play content, hear it, adjust volume etc, but not matter what I do, I cannot get it to display a picture at all.

I have tried soft resetting by unplugging it for 30 minutes, holding the power button for 60 seconds etc. Nothing works.

It's this TV. 
I can't even download a firmware to attempt a manual update.

Hello,
I was doing Webos 05.30.11 update on my Nanocell SM8100PVA when I saw your messages, I stopped it at 97%...
Have you been able to solve your problems ?
 

I don't know what is wrong with my tv.

The image came back for a day, then on day 2 the left side of the screen started dimming every few seconds, then full bright again.. but now with scan lines.

Now it's completely dead again :(

Have you tried to reset your TV to factory settings, and to call LG support ? an official patch shouldn't break the TV this should be covered...
Your description remind me a not compatible screen resolution or frequency...

I've tried everything.

Sometimes the image comes back, but only the right side of the screen.

I feel sorry for your tv, I really hope LG will fix your it.

If only it was not so complicated to downgrade firmware...

      Hi I recently updated the software to 5.30 version, and after that I noticed a weird problem with video streaming, in general issue with internet bandwidth. Usually my b/w is ~35 mbps so that is sufficient for 4k streaming on youtube or netflix. The issue is after running for 10-15 mins if I pause the video or go backward the network speed is thrashing badly. For example when I check internet connection on netflix it shows ~30-35 mbps, but whne that problem occurs and I check the speed again I see the speed is dropped to <1mbps. Same with youtube, it can't load 4k videos anymore as the speed is ~1mbps. I can realize the problem as the thumbnails load very slow with scrolling. This problem does not get away unless I restart the TV or disconnect from wifi AP and connect back. The router always works fine I mean when I observe the problem on tv I can run videos on mobile seamlessly and see a speed of ~40 mbps on the same router. The router is kept next to the TV so I don't think it is some issue with wifi distance etc. I don't know what to do. I tried resetting but it removed all my app but it was actually not a so called "factory reset". So software version remained same. To rule out hardware problem I want to revert to previous version of the software but apparently I can't downgrade the software. Is there any other approach to load some previous version firmware?

      Hi,
      My problem is that my Netflix app on my LG tv (OLED65B13LA) keeps selecting the leftmost button, it's impossible to scroll the cursor to the right to select another button. I tried resetting the tv to factory defaults - after installing Netflix again the issue is exactly the same.
      I also tried disconnecting the tv from power for a few minutes. Plus I contacted Netflix, but they said I need to contact TV manufacturer before they log a possible bug in the app :/.
      My Amazon Prime app works perfectly fine on the same tv.
      Any thoughts?

      My TV is an LG OLED 65B6P, which was working fine until a few days ago, when the magic remote pointer and OK button stopped working (was getting message that Bluetooth needed to be initialized).  After making the mistake of calling product support, they had me do a factory reset, but that didn't fix the issue, and only made it worse, as now I can't proceed from the "Start Up" menu as I can't click the OK button.  I'm dead in the water, and have even tried this with 2 different magic remotes!  I've tried the pairing and unpairing suggested on numerous support sites, and can't get anywhere with this.  Can't even find an LG service center in the Boston area.
      I also have a Harmony Ultimate remote, but that likely won't help here, as I can't get the "OK" button assigned in the TV's current state.
      Any help is appreciated!

      We have two LG TV's that stopped connecting to our PLEX media server after the last update. TImes out saying "Checking connection speed to Raspberrypi" which the PLEX is on
      Upgraded the Mesh Routers before trying anything, still only the PLEX app doesn't work
      Our other TCL TV and Roku and TIVO still work with Plex, so this is only the LG TV's that can't connect anymore.
      Another annoying error after the last update is that any Streaming app (Amazon, Netflix, and DIsney) now fall out of the app and go back to HDMI port 1 if we pause for 30 seconds.  Which we have always done for a Bathroom break or getting drinks.
