Re: LCD LED EDID EEPROM Dumps

thanks smdflea already tried different screen still cannot detect.i have a question how to determine the type or manufacture of 24c02 chip on lcd screen?

Re: LCD LED EDID EEPROM Dumps

Ok, so i got a screen and programmed it with my old TL866 by jumping 2 test pads together with tweezers. The screen is a AO N156BGE-L11 .I jumped EE_GND and EE_WE (from pin 7 write enable/write protect) and it worked without having to desolder or solder wires from pi4 to 7.Check if your pcb has a similar silkscreen .

Re: LCD LED EDID EEPROM Dumps

thanks i already tried but still no luck maybe the chip is damage.but some of lcd already programmed i put only at2402 and some of them done programmed but others are error. is it possible to replace 2402 chip from other lcd

Re: LCD LED EDID EEPROM Dumps

The lcd iS CHI MEI n156bge-l21 rev c1 and the chip with 8pin on the lcd board has only written 4327 6249

The marking code could be a ST Micro M24C08 ,M24C32

Re: LCD LED EDID EEPROM Dumps

thanks smdflea, how do i know if it is OTP?

Re: LCD LED EDID EEPROM Dumps

and also is it possible to make a 30pin led connector?so that every 30pin screen can programmed too.

Re: LCD LED EDID EEPROM Dumps

thanks smdflea. i keep searching for this endid bin do you have this N156B3-L02 REV C1

[SMDFlea]

Re: LCD LED EDID EEPROM Dumps

No, i don`t have it. Heres the datasheet,on page 15 is the EDID layout:

@SMDFLEA I need a EDID eeprom file for this AU B140XW01 V.9 please!!I try to flash the corrupted screen

Re: LCD LED EDID EEPROM Dumps

Can I get dump for BOE NV156FHM-A11

Here you go.

Sorry, i don`t have the dump or datasheet

Re: LCD LED EDID EEPROM Dumps

@smdflea not working because your file has 128kb and the flash size for this is 256kb

[SMDFlea]

Re: LCD LED EDID EEPROM Dumps

You can use a hex editor ?

Re: LCD LED EDID EEPROM Dumps

i dont know how to use it to make a file size larger, can you please make it 256kb file please

[SMDFlea]

Re: LCD LED EDID EEPROM Dumps

Heres a 128kb FF file,copy and paste it onto the end of NP355V4C_B140XW01.bin
