    I have a TV of LG model no. 42LF5809-ZA and it stuck on LOGO of LG. I just tried to put USB to make an update firmware but unnecessarily. What I have to do ?

    Quote:
    AI: Can you describe the steps you followed when attempting the firmware update via USB?

    Download the file from LG site and make FAT32 USB I named LG_DTV. I put it on TV in USB Port 1 and TV didn't respond.

    AI: Have you tried any other troubleshooting methods besides the firmware update? If so, what were they?

    No

    Replacing the motherboard will solve your problem, hopefully there is no other repair option
