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

IC1603 (SPI Flash W25Q80) contains the T-CON firmware (all data and settings of your panel), rearranging that resistor will not give you anything.

Does this number match the number on your panel tag?

Yes, indeed!

nomoresonys: I was not sure which way would be best. After lotas pointed out why moving IC1603 would be a solution I will try replacing it.

I guess there is no other way to flash that IC with different T-CON data (e.g. via USB stick)? I have done so before with a philips tv.

And lotas: I agree with your observation. Board A does not show any signs of burnt components and the whole TV is quite dirty and might have been in a kitchen with smokers.

And also for different panel models (manufacturers) on the motherboard in the T-CON area there are positional resistors, jumpers and they also need to be rearranged, as on the original board, put both boards in front of you and compare all the places and set them as they were on the original, here is an example that I noticed...

in short words, forget to use boards B, or change any parts. on Boards A, just freezing the answer to repair fault sectors on chips,

Well that would sure be a lot easier if it works.

@lotas: thank you for pointing out the differences of the boards which may explain why the image on board B is distorted. I have added a picture of board B (distorted). Please notice the panel itself shows three vertical lines which is a fault of the panel.
The distorted picture (board B) has an offset to the bottom and displays many more vertical lines
I did take over the service panel type from board A (which is the original board for that panel) and set it in board B without noticeable change.

I could try to move the resistor from position 3 (distorted) to position 1 - or would there be more differences between the two boards?
That would be easier than replacing an IC.
What I can tell: the working board from a curved mu6279 has its resistor at position 1 like board A.

@lotas: Could you explain why replacing the IC1603 in your post #3 would help getting rid of the distortion?

First and foremost, is your screen actually this blue? Or is this the distortion you're referring to? If it's appearing blue then you have bad backlights. Are you not able to source a replacement board from eBay or elsewhere? Moving the chip from one board to another is much more effort than it's worth, especially if you DO have bad backlights on top of it.

I had a Philips that did exactly what you're talking about. It would not save any changes I made. I would delete the Google account tied to it, reboot or and the account was there again. The tv would also randomly freeze up and reboot itself, sometimes successfully, other times not. It was due to a failed Hynix NAND which are pretty notorious for premature failure. Replacing the board entirely fixed the issue (a later revision with a different manufacturer of NAND).

i insist to say it must be tested every supply rail, for the emmc the VCC, VCCQ, VDD , a low 3,3v maybe can make reads but not writes, another issue can be in the user partition, it can have structure problem so it is not mounted at start, you can try search for the debug port and connect it to PC with terminal program to see the log..

leds are ok because of the pictures of original MB working, swapping a sop8 is a very easy job and worths for a 32" chinese tv, let's figure it for a 55" Samsung..
