Samsung UE55MU6102K IC1604 dump needed - TV don't start

[totof]

Could you help me...
I have a Samsung UE55MU6102K with the following problem : I disconnect the motherboard from main power supply from and the backlight leds light up.
Then motherboard connected, standby led is on and current consuption is 18W.
Then trying to start the TV, the standby led is blinking once but TV don't start and standby led stay red.

Maybe the firmware in the IC SPI Flash W25Q40CL (IC1604) is corrupted.

The model of my TV is :
Power supply BN44-00807A
Main Board BN41-02568B / BN94-12765W
Panel CY-GM055HGLV3H

Here is the dump of my IC1604.

Does anyone have the binary for this TV model?
Thank you.

This dump is working, I threw it off for you to check and you had the same thing, this dump is native or has already been rewritten by you or someone else, the behavior of the TV is as if a dump was recorded with a different version of the software. If the 25Q40 firmware flies, then the TV will not turn on at all, the standby indicator will not even light up.

Thank you lotas for your response.
The standby led is always red, it only flashes once when I try to turn on the tv.

After starting the TV, with your file 25q40, the content is not exactely the same : from address 0006F000 to 0006F17D 0xFF are replaced by other values and from address 00070000 to 00070DDF initial values are replaced by 0xFF
However I also put status register to 0x88 and 0x42 after writing using NeoProgrammer 2.2.0.10


I don't know the history of this TV, I don't think it has ever been reprogrammed by anyone but I can't be sure.

If so, what would it take to fix it?

In this "MU" series and not only in this one, the software version in SPI 25Q40 and in eMMC should match, if the version does not match, then it will approximately behave like yours, select different versions (there are only 6-7 of them), diagonal and the model difference does not matter, the main thing is that the series be "MU".

Thanks.
Is there a simple solution to program eMMC ? it will be interesting for me

I'm looking for a UE43MU6105K motherboard and I will try with this card.

Re: Samsung UE55MU6102K IC1604 dump needed - TV don't start

eMMC can only be flashed with a programmer, and if you flash eMMC, then you need to flash it with the entire working kit (eMMC, SPI 25Q40, EEPROM 24C512).
If you install another motherboard, then you need to rewrite or rearrange spi 25q80 - this is T-CON (it is responsible for your panel.

OK.
I will try to dump the spi 25q80 of the original motherboard and rewrite it on the new motherboard.

I have found another motherboard BN41-02568B / BN94-12643A for TV UE43MU6105K (not UE55MU6102K).
I see that some resistors are different from the two motherboards. Do you think it could works this my panel if a only rewrite my 25q80 on the other mothboard ?

Re: Samsung UE55MU6102K IC1604 dump needed - TV don't start

Yes, it happens on the boards in the area of LVDS connector that they put optional resistors or jumpers (zero resistors) for certain panels.

Thank you lotas, I will try the other motherboard

It is better to find "55" for your diagonal or very close to "49".

Re: Samsung UE55MU6102K IC1604 dump needed - TV don't start

okay it's safer and I don't want to do anything stupid :-)

Re: Samsung UE55MU6102K IC1604 dump needed - TV don't start

I found a motherboard but for another model UE55MU6645 TV.
Now the TV starts well and, having not reprogrammed the SPI 25Q80, I have vertical lines on the image and the colors are not beautiful.

If I understood correctly, now I have to copy the contents of SPI 25Q80 from the original motherboard to the new one?

Re: Samsung UE55MU6102K IC1604 dump needed - TV don't start

I put the original SPI 25Q80 (from mainboard UE55MU6105) on the new mainboard (from UE55MU6645) and now the image is perfect.
Problem solved

You did everything right, that you bought from 55 diagonals and threw the t-con firmware.

Once again thank you lotas for your advice.

Hello,
totof lotas : I am reading the 2 first posts of this thread and I have the feeling that lotas provided a working .bin to totof, but I cannot find it linked.
Can one of you provide me this bin ? I have the exact same problem with the exact same TV model.

You need to post your non-working dump, I will fix it.
