Could you help me... I have a Samsung UN55MU6103F with the following problem, dead TV, I disconnect the main power supply and the leds light up. I know it is a problem in the firmware in the IC SPI Flash W25Q40CL (IC1604)

Power supply BN44-00807A
Main Board BN41-02568B

I leave my backup of the dump and a little extra, it is the schematic of the power source, it can be useful to someone. Regards... -

The capacitors physically look clean (no bludgesor leaks) and...
