Hello all, is anyone able to help me with my issue, please? I just tried to update firmware on my LG TV 55UG870V-ZA by manual method (download firmware file from LG website and extract it to USB flash drive into “LG_DTV” folder). Everything seemed good, so after update completed, TV was restarted and after restart only strange flashing screen without any normal image… In this moment I can only turn off TV… Before fw update, my version was 2.xx.xx and I try to update 4.05.45 … Is any way how to fix it? Some factory default or restore previous fw version from some service menu… Many thanks, I am desperate from this :(
Hi, From what information is available about the only thing that you can do is to replace the mainboard. Here is a link for one (I think - check the board number in your TV to verify) that is no longer available just to give you an idea of the cost. I haven’t found any others but then again it is easier to locate if you search for the board number than just the general term of LG 55UG870V-ZA mainboard. http://www.ebay.ie/itm/192019582871?clk_…
