    Re: Sharp LC40LE531E Red/Green flashing LED

    OK, I have the FW.zip file.
    Which file do I need to flash and how do I do it?
    Is there a YouTube video you can recommend?

      its better to flash the bootloader first then the main firmware

      extract the zip and put all file you have on USB stick formatted FAT ot FAT32 the usb stick will be better with max 1GB . insert the stick in tv press P+ or ok on RC and turn on the set.. you can see the USB stick led indicator will blinking... give time for it... after it finish flashing and every things went ok.. the TV will restart and initial it self

                Last question:
                How does the BIOS/SW become corrupted in the first place?

                  the Main boards design are early one from vestel where they missed up with so many parts where now at the new design are to much less parts. beside the quality of some brand parts of NAND RAM EEPROM developed in good way... SOME BRAND NOT ALL... as we experience many become more bad than before.

                    Good fix indeed.
                    Now you should take the Voltage readings as reference for future repair.
