Samsung TV mu6179 with Mainboard BN41-02568B wont save configuration.

[fixitforfree]

I have two Boards BN41-02568B for a UE55MU6179 of which one does produce a good picture (Board A) but can not save its configuration (even a factory reset will not work) and one board which produces a distorted picture (Board B). Learning from here the IC1604 saves the configuration of such a TV.

Before replacing the IC1604 from Board B to Board A - would that actually solve the problem from Board A not being able to store its configuration or could there be something else wrong with writing to the flashrom? Is it even the right chip to replace or should I look out for a different one?

Thank you very much in advance for your insight!

ic1604 is the standby software, it does not contain profile, the settings are stored in the emmc flash, the reason why it can't save is that probably the user partition is not more accessible due to FS error, the most sensed thing to try is to update the software but i do not think the procedure will touch the user partition... furthermore Samsung are protected by all type of serial port programming.. needs direct emmc programming..


PS: ...or you can crawl on the floor to Samsung asking for a repair update, i know they don't give to you

Move IC 1603 (W25Q80) from board A (where the image is good) to board B (where the image is bad), as I understand it, board B is not original, from another TV (donor) and with a different panel diagonal.

the boards comes from the same tv model? if yes can you post a photo of lcd panel internal sticker?

Both boards are BN41-0286B and are both from a UE55MU6179.
The idea is to take the working IC from Board B (distorted pic) and move it to Board A. If the configuration is stored in the EMMC flash, then I would try to switch that IC. Which one would that be?

BTW: the board model seem to be used in a variety of different Samsung TVs. E.g. the same board is used in a UE49MU6279 (curved) and works in the UE55MU5179 chassis.

Davi.p: which sticker are you referring to?

[Davi.p]

I don't know how is and why the distorted picture, but if you are able to see the menus, and if the problem is the different panel, then you can try to enter the correct panel type in service menu, every lcd panel has a white sticker with the model, i need the photo

I don't know how is and why the distorted picture,

Because each motherboard had its own panel, from different manufacturers.

YES I UNDERSTAND, it's easy, but we don't know the real problems.. needs to know everything...

In the 3rd post I explained what needs to be done.

So when it has to be changed the service panel type setting?

[lotas]

I don’t see how bad the image is, maybe there’s nothing visible there and how you’ll change the panel in the service, stupidly, at random.
