After updating firmware 04.71.25 pic is degraded on 55UM7450


Cudnovati Sisavac

Question

Maybe I didnt noticed that before. But when watching TV programs (DTV, via antenna, DVB-T2/h265) I noticed that logos arent super crisp, sometimes like they have those artefacts around them, noticable specially when looking from close, like when you have in tube streaming, also similar artefacts can be seen when looking at TV telps with lots fo jpegs/inforgraphics). Its noticable on pictures (human faces) but less. Like some pixelisation.  Some channels are better but....I doubt that has anytging to do with update but I want to be sure if that is possible....the last two updates (newer than my stock firmware) came with minor fixes (says nothing about processing or picture). What do you think?

I have 55UM 7450PLA LED TV. I manually updated from 04.07.20 to 04.71.25 (firmware downloaded from official LG page for this model).

      webOS updated, I think to 2023, on my C2 a couple of days ago. Since then the News option on the Sky News app no longer works, instead timing out. The Weather and Climate options still work, though.
      I have deleted and reloaded the Sky News app, but the problem remains.
      Does anybody have any suggestions of what I might try to get this working again, or is this something for LG, or Sky, to fix?

      Hello,
      I have a problem with my new LG OLED G2 newest version 4 firmware.
      I tried sorting my satellite channels with chansort programm from github, because sorting them with the tv remote is a pain.
      When I try to sort them with the remote and have selected about 10 or more channels all the selected channels get suddenly getting deselected, so I can only select up to 10 at a time  to 
      sort them -> must be some kind of firmwarebug? 
      After exporting the channellist to a usb stick then editing it with chansort an importing it back into the tv all my channels are gone, all transponderns are deleted.
      First I thought it was a charsort problem but all channels and transponders get also deleted when I simply export them to a usb drive an import them back, without editing the file at all.
      Does someone know how to fix this problem? 
      And yes I´ve done multiple factory resets -> did not fix any of this behaviour.
      I also discoverd another bug the deletes all channels, because I needed to reboot the tv I searched for a reboot option in the tvs menu, but there is no reboot option.
      To do a full reboot (except from forcing it through cutting the tvs power) you can deselect the privicy agreements, after that the tv reboots, but then all channels are gone too.

      After viewing photos/videos on a flashdrive plugged into the USB of an LG TV and using SmartShare to view... and then removing the USB and then no longer having access to the TV... I noticed on the flashdrive a new folder called "LG TV" and within what appears to be files that may have been the thumbnails displayed on the TV. My question is... do those thumbnails also remain on the TV as recent history even without the USB plugged in? The LG Smart TV online user guide refers to "Recent" ("To view a list of recently viewed or added content, select Recent). Would thumbnails be there without the source flashdrive?

      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.
