[bohaboha]

Hi I've read all the post in this thread trying to find something about UEXXTU but not a single one about it except EUXXMU basically my search lies in finding which IC chip corresponds to 25Q40 on my own board :BN94-16627N the patch and BN41-02751B-000 on PCB hopefully lotas can enlighten me

It won't be possible to restore it, since it's not a dump, either you counted it incorrectly, or someone wrote something incomprehensible there. What happened to the TV, what's its history?

I called the customer, they told me that they tried to repair it but he doesn't know if they tried to program it, I asked if it is possible to have the original file if they saved it

I compressed the dump in winrar, is there any way to repair it?
Is there any way to get this TV to work?

It doesn't seem to you, but it is true, some smart flasher, without unpacking the dump from winrar, wrote it down just like that!

I have this TV with standby LED off, I downloaded the dump, it doesn't seem original to me, is it possible to try to repair it?

hmmmm...take a look at the picture please, i thing is something wrong

Yes, it is not so, it should be so.

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).

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!

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!

Hi, your dump is fine, working, the problem is different.
