SAMSUNG UE55MU6405 - no standby

i mean the firmware....if you have it

[lotas]

The firmware is different, when updating the software via network or usb, the data in the 25Q40 also changes and the old version (dump) will no longer help (it will not match the eMMC software version and the TV will not turn on, you need to read the data (dump) from the 25Q40 and post it here, I'll fix it for you (if it's damaged).

Are you talking about the original mainboard? Very good...tomorrow when the programmer arrives I will try to copy the 25q40 software and send it to you.

[Jmenuu Zavalichi]

from the original mainboard and if is dosnt work y will copy the file from ic1603(original mainboard) to ic1603(new board)

Yes, copy IC1603 from the original board and replace this dump in the new board and check if the image changes.
Or just unsolder it and replace this chip on a new board (this is without a programmer).

Yes.

Hello friend...I'm trying to copy the chip...it detects it as epprom and tells me to put it in manually...any of them that I put in tells me that the chip is empty...it could be a problem of the program?

[Jmenuu Zavalichi]

el chip is this...can you help me?

[Jmenuu Zavalichi]

I haven't been trying for days...with the tweezers (which are useless) with the ch341 programmer that burned...I bought a SOIC8 cable that didn't work for me...in the end I had to modify it...so that It matches the pins of the chip...it seems to connect...so it's fine...but I don't know what's wrong...the program I have or the Windows 11 that I have installed on the PC ...but I installed the drivers and it says the programmer is connected

[lotas]

I don't understand what you're doing, why are you touching the SPI flash IC1603 (25Q80) chip, are you having problems with the image on TV?

[Jmenuu Zavalichi]

If you look at what we have talked about before, you told me to do that

[Jmenuu Zavalichi]

I don't know what the programmer could be, it connects perfectly but any chip that reads tells me that it is empty

[Jmenuu Zavalichi]

Hello friend, have you found out something?...what could I do...I asked for a clip to hook the IC properly yesterday I did a little research and lowered the speed of the ezp2019+ programmer and it read but I think it's not complete tx I'll tell you

Hello friend...I finally managed to extract the bin file of the 25Q40 ic from the original motherboard that does not have standby (as you told me to send it to you to see if you can fix it) could you? I'll send it to you here...I'll try tomorrow to copy the file from the 25Q80 to the motherboard that I bought, let's see if it works for me (I remind you that I sent you some photos with the image of the TV that doesn't look complete, it's only 75% complete and distorted colors) thank you and I'm waiting for answers, let's see if could you modify the bin file

What kind of dump is this, where did you read it from, it does not correspond to 25Q40, did you mess something up, is it numbered IC1604?

This dump looks more like a 25Q80, but you read it as a 24Q80 (IC1603).
