How to replace Firmware on LG-42LB650T Television with WebOS 5.05.70
I have had this TV for 6 years with No issues. Since about 2 weeks ago when I watch non-HD channels via STB or Wireless the Screen randomly freezes, then goes blank, shows LG screen, and returns, works normally for few minutes till repeats. When I watch HD channels via STB or wireless, It has no issue even if used for few hours. I tried a reset to the initial setting and that did not help. Upgrade said no upgrade found. Has Webos 05.05.70. Is this a hardware problem or a software problem? How Can I replace the firmware? Please advise. Thanks
I think that the only way to replace the firmware is to replace the firmware IC on the mainboard or to replace the mainboard.
Looking at the update instructions for your model the TV already has the latest firmware installed and a manual update via USB flashdrive won’t work if the update file on the USB drive is the same or a lower version than what is already installed in the TV."
