Re: Un50mu6070 Mainboard issue
Hi Lotas,
For xxMU6xxx series you have to set on the programmer "STATUS REGISTERS"
0x88, 0x42.
For xxKU6xxx series is the same rule and the same set for SR (0x88 and 0x42)...?

Hi Diah,
When i use remote access for power on led for stand-by is blinking but mainboard don't start BKL.
And yes, BKL is active when i disconnect mainboard from power board.
So, maybe i need to write 24c512 as well but i don't have any dump for this model,...,
Have somebody a full dump for this model, UE55MU6172...?

Re: Un50mu6070 Mainboard issue
I see that you write in the post:
In the program:
1. Click "Detect Chip" and select W25Q40CL and "Select IC".
2. Click "Unprotect".
3. Click "Erase 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 "Edition SREG", put a check mark on S7, S3, S14, S9 and press...Leave a comment:
