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

[lotas]

Can you tell me what data is corrupted, so that I can recognize if a file is corrupted or not.

Basically, the header in dump with a size of 4 kB (initial bytes) FF FF FF..... flies off, and the status register itself.

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.

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.

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?

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

[lotas]

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!

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).
