Hi, Lotas!
I have samsung 55MU6400 with mb bn41- 02568b (bn94-11958Q)
the Tv does not work, the red Led does not light up, and when the MB is turned off, the baccklight works. Could you please fix the firmware for it?
Thank you very much, but the TV still doesn't work, there is no response to the power button, I set the status register as it should, but after turning on the beginning of the dump is destroyed, please tell me what could be wrong.

What programmer do you have? If CH341A, what program do you use for it?
And how do you record the dump, what is the order in which the commands are executed?
I read the dump with SVOD3 , but the status registers in it are not entirely clear, so I took another programmer - Chipprog-48. I pasted a picture with the status registers from it

when I read the dump again, I see that the beginning is FF, I load fix , I click erase then write, then in the security register column I select read, I go into them, I see that everything is still the same as I set it up

The procedure is as follows: 1 - Remove protection (uncheck all checkboxes and record St. Reg.) 2 - Erase the chip. 3 - Record my Dump. 4 - Check the recorded dump. 5 - Check the boxes in the Status Register (0x88, 0x42, 0x00) and write to these registers.
Thank You. It works!
One more question - how to modify dump? I checked some dumps form You from this side, I see differences from 0 to 01000 address but this countain is different from different dumps.

hello ...can you check if this is files is correct UE55MU6122KXXH Thank you
25Q40 is working, on the second one you need to write what the panel is and what's wrong with the TV, why they decided that the problem was in the firmware.
