Good afternoon, I have a Samsung MU series locked, it does not boot, the power supply is ok, most likely the IC1604 25Q40 file is corrupted.Comment

Everything is OK with the firmware (dump), read the dump from the chip again and show what status register is set for the chip (it should be 0x88, 0x42), what is the problem with the TV, is the standby LED on, does the backlight light up if you disconnect the cable from the power supply to the motherboard?, have you disconnected the lvds cables from the panel?Comment

Thanks for your interest, I reprogrammed the same file on a new 25Q40, register at 0x88 0x42 and now the TV has started working again.
I will keep it to test, I would not want there to be some problem on the main.
Power, backlight and panel are ok.
Can you tell me what data is corrupted, so that I can recognize if a file is corrupted or not. Thank you very much for your support.Comment

I have a Samsung UE55MU6102K with the following problem : I disconnect the motherboard from main power supply from and the backlight leds light up.
Then motherboard connected, standby led is on and current consuption is 18W.
Then trying to start the TV, the standby led is blinking once but TV don't start and standby led stay red.
Maybe the firmware in the IC SPI Flash W25Q40CL (IC1604) is corrupted.
The model of my TV is :
Power supply BN44-00807A
Main Board BN41-02568B / BN94-12765W
Panel CY-GM055HGLV3H... -
The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:
