Thank you, lotas, but it didn't help.
This is my home TV. When it broke, I took it to a service center. They diagnosed it as a broken processor.
I repair other electronics and am not an expert in TVs, but this seemed strange to me. So I decided to try it myself.
In 25q40, I found that the firmware start was missing and searching the forums suggested that this was a common problem. But fixing this problem resulted in the standby voltage appearing, the TV started to turn on, but there was no image.
Scratches on 25Q80 indicate that they tried to flash it without unsoldering it. This makes me think that I will have to further improve my skills in TV repair.Comment

If the TV was already at the service center, then it is possible that the 25Q40 already had a non-original dump, maybe they tried to program it without saving the original one..Last edited by lotas; 12-29-2024, 12:02 PM.Comment

If this is not the original dump, then why is it also corrupted? I hope this is the original. Maybe you're right.Comment

A working Dump is damaged immediately after power is applied, if the status register (0x88, 0x42) is not set after writing; if the service center did not do this, then it is damaged again.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... -
by Habble7The 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.
