I have a 49UB850V-ZD smart TV and has the issues below. Can’t understand if its a software issue or components issues:

  1. Can’t reset using meniu. I can access the meniu, I inserted pin 0000 and if I try to click Confirm it just flashes the button with no success. If I click Cancel then the meniu closes
  2. The Live TV channels are not working. There is no issue with the provider. It just not plays any channel
  3. If I connect the usb or hard-disk driver to play some movies I can navigate thru folder but I can t play any
  4. When I connect to Netflix or youtube I can navigate but if i try to play it does not load.
  5. The remote TV does not work anymore -> Only the Power Off/On button
  6. I have a magic remote TV for LG and works to navigate with the indicator
  7. The button of the TV (under the TV led) works only to open the TV -> the menu does not work anymore
  8. In the advanced menu, the Channel settings is not active among other options that are disabled.
  9. 05.05.90 is the latest upgraded version on my TV. The upgrade was done in December or January and it worked just fine until now. What do you think? What do I need to do? Could this be an: Software issue?Hardware issue? If so, could it be the motherboard? If its an software issue, how can I downgrade? What tools do I need to have? Pictures:

Hi, Since the TV isn’t working that well anyway, try updating the software V05.05.90 and check if that resolves the problem. Please make sure that your TV’s exact model number is shown in the Reference link shown below the software download on the right hand side of the page, as installing the incorrect software can “brick” the TV. If the TV already has this version installed then it cannot be re-installed. There will be no Install message displayed on the screen during the update procedure. I’m a bit confused as to whether or not you can navigate through the menus to see what software version is already installed, so if you can’t all you can do is try it and see what happens Download the TV software Update Guide which shows how to install the update using a USB flashdrive.
