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

[yureyko]

Maybe I have a problem with the SPI chip or the CH314A programmer. Mine is not modified. Do I necessarily need to modify it?

There should be only (S3, S7, S9, S14).
Try to record your native dump again via NeoProgrammer_2.2.0.10.

In the program:
1. Click "Detect Chip" and select W25Q40CL and "Select IC".
2. Click "Unprotect".
3. Click "Clear IC" and "Yes".
4. Click "Open File" and select your corrected dump.
5. Press "Program IC" and "Yes".
6. Click "Verify IC".
7. Press the down arrow to the right of "Unprotect" and select "SREG Edit", put a check mark on SRP0, BP1, CMP, QE (S3, S7, S9, S14) and press "Write" and "Yes"
7. Close the program. Ready.

Dear lotas ,
I already have some default parameter set. That's why I can't set the register code 0x42.

Then check what status register is set, maybe it has crashed (it should be 0x88, 0x42).

Dear lotas ,
After installation in the TV, the status changed to 0x46.

Interesting...
All voltages are present, but the indicator does not light up.
However, when I try to flash the SPI with a working firmware from a similar model, the indicator lights up, but there is no startup...
