Eeprom dump thread!

Try it, don't forget about status register (0x88, 0x42).

With this file the led is now red and flashes when sending commands. The tv still doesn't turn on.
The processor heats up even if the tv doesn't seem to do anything.
I read the post about the registers and I hope I programmed the chip well.
Thanks anyway for your support.

Hello everyone, could someone help me check the bin file for a Samsung UN75MU6103. Ver. FB03. or if you have a working backup, would be greatly appreciated. The Standby led is turned off, still if joystick is pressed or powerd on by remote, it flashes, but nothing happens. All voltages are present and there is no short circuit on the board. Thanks in advance!.

Yes, everything is possible, have the usb and hdmi ports been checked for short, low resistance relative to gnd?

Yes usb and hdmi ports fine, dc converters too, not found from the same board original firmware emmc nor w25Q40.

Thank you Lotas, is it possible that the failure was caused by the Emmc firmware?

It responds to remote on and off, but does not turn on 12V power for pmic.

Dump is ok.

The kernel and software in your dump are fine, try recording your dump with the NVM removed.

Thank you, unfortunately the screen still does not turn on, it only shows the standby LED.

Thanks for your patience, yes I have that motherboard, I was able to extract the following bin file from the non-working flash, I would really appreciate it if you could help me take a look at it

As I understand it, you have such a motherboard, you can read your non-working firmware (dump) from 25Q32CSIG and post it here, I’ll take a look.

Thanks but unfortunately, the problem is the same with this dump, i noticed the graphic tcon also have a winbond 25x40bv, do you have a dump for this one ?

T-CON IC601(W25X40BV) - it does not play any role in rebooting, you need to program EEPROM/FLASH - IC801(W25Q40BV) IC802(S24C256C)

Try programming two chips at once with this set, just save your original dumps.

[univers73]

Try
