Samsung "MU" series (UN, UA, UExxMUxxxx) fault dump IC1604 25Q40...

[pepebmx]

Hi, I have a Samsung TV model UN43MU6100GCZB (mainboard BN41-02568B BN41-02568). It first had random HDMI issues, then progressed to turning on with backlight but shutting off after a few seconds. All main power rails are present. Could you please check this dump? I suspect its the main problem. Thanks a lot!

Hello. I also have a samsung ue65mu6172 with the bn41-02568b motherboard that doesn't turn on and doesn't have the standby LED. From what I saw in the hex of the W25Q40CL chip, it seems to be corrupted at first. Can you help me with its repair? Thank you very much!

If this dump is native, original, then it works.
Read the dump again with the programmer and see what the programmer shows about the status register, what it is set to (should be 0x88, 0x42).
