Eeprom dump thread!

[Andreas_de]

Here is a dump of a Samsung UE48HU7590: Board is HU8500 BN41-02257B. TV starts for 1 second with "Smart TV" logo and then turns off screen. No reboot loop. Maybe you can find here a defect in the SPI EEProm. I added the second EEProm which is behind the little black heatsink as well in the ZIP.

Here is the SPI dump. Thanks for your help.

This dump is ok, working.

This dump has nothing to do with standby, this spi flash belongs to T-con, look for spi flash 25Q40 on the board.

I have a Samsung UE65KU6099UXZG with no standby LED. Voltages on Motherboard are fine (5V, 3,3V, 1,8V). Here is the EEPROM dump. Maybe it is bad?

Thanks I thought as much but just thought it might save me some time taking the flash ic off and programming it.

Thank you Lotas
Is the Fuego 40FG4505 a USB file as well as it is only 6748kb and not 8192kb?

Yes, it's USB, you can do it on the programmer...The programmer itself will add the rest (FF, FF....)

Try...

Looking for working dump for a PROSCAN PLEDED4022-UK with mainboard TP.SIS231.PT851 with screen V390HJ5-XCPE1 or a working dump for the same screen and main board.
I have looked on the web without any success for the dump of the Proscan TV.
Any help would be appreciated. Thanks in advance.

I'm talking about this TV

This firmware has nothing to do with the wi-fi module and has no bearing on it.

[ransoms.juggles]

lotas how to you fix the firmware? Is there a specific software you use to analyze it that flags bad hex? Sorry my ignorance, I’m still learning.
