    Pannello : Samsung LTA400HM13

    U103 = 24C64
    U107 = M25P40


    As for the ignition, the red to green LED flashes at infinity.
    The feeds are regular.
    I have planned
    U103 = 24C64
    U107 = M25P40
    Unsuccessful .
    I'm trying to load the following FW: LC-40LE340E_Software_Version_V-0-12-3.
    I performed the installation procedure fw, when I turn on the tv
    from the mechanical switch it is positioned in stand by. (red LED on). turning on by button
    power the LED flashes from green to red and does not read anything from the usb.
    I changed multiple usb sticks, formatted in fat 32 and copied the files to the usb root, but nothing changed.
    Procedure made several times with usb from 1 gig, fat 32, ignition plus OK button, switching on with button from remote control P +.
    The pen is not read.
    The voltage on the usb port is present, 5 volts.
    Thanks and good job .

    Hi, It's not a software problem. This model suffers from soldering to the BGA processor. I solved several with this symptom by reworking the bga.
