Re: Samsung ue49mu6120
Hi Loats,
THX having time for me.
If I look at the dump, there are many YYYYY somewhere after first 1/3 of file? Is this normal?
What else can be a problem?
Do you have some other dump in your database which might work on my TV, I can try?
TV model: UN49MU7600FFXZ, board: BN41-02568B...

Hi Lotas,
Finally the AsProgramer identify the W25Q40CL, however the IC is empty. Did I delete it while experimenting with the software.
So, I don't have native dump. Would you please give me some just to try, I have nothing to loose.

Re: Samsung ue49mu6120
It could be dump damage or the IC wasn't read.
When I press the question mark button the IC is not recognized. I am not sure did i place the IC properly in the right section.
Should it be placed in 25 or 24 section?...Leave a comment:

Re: Samsung ue49mu6120
Thanks for your prompted response. Yes, it is Samsung btw. I did take off the IC without problem and have attached to the CH341 adapter using clamp on the cable (picture attached). AsProgrammer is active, get the red and yellow light (while reading), however the reading is empty like without the IC (picture attached)?
Do I make it wrong, can you please review the attached picture.

Re: Samsung un49mu7000f dead no power
With a huge delay, may I have detailed instructions. I have located the Chip on the main board. Should chip get removed? ]How to connect the mainboard 8 pin chip to CH341A hardware? I guess USB goes to Laptop and software?
