    Telefunken T50FV275DLBPOS - Blue leds blinks

    Hello
    I have a problem with a Telefunken LED TV that only flashes a blue LED.
    No lighting, no sound.
    Someone changed the contents of the 25l1606 flash.
    Do you have complete flash content and NAND content.

    T50FV275DLBPOS
    Vestel 17MB95M
    panel VES500UNDA-2D-N02

    Please give me the steps to solve the problem

    Thank you.

            and put the 2 file after extract... edit the file usb_auto_update_A1.txt

            delete all and just copy and pasta the following

            Code:
            # <- this is for comment / total file size must be less than 4KB

#mboot
#For pure mboot.bin upgrade, use below part
fatload usb 0:1 80400000 mboot.bin
spi_wrc 0x80400000 0x00000000 0x0120000

#For mboot_spi.bin (padded to 2MB, added logo, edid/ddr etc) upgrade, use below part
#fatload usb 0:1 80400000 mboot_spi.bin

                    Greeting
                    I finished the USB upgrade.
                    I submit a report with UART
                    There was a gray screen during the upgrade.
                    The TV still blinks and won't turn on.
                    Please give me further instructions
                    Thanks..
