        The IC is fine. I can read and write to the IC and verify data. Just don't have the right data file for it. Hopefully at some time it may become available. Not in a rush since the set has a bad panel anyway. Thanks.

            Have you got a NAND flash programmer??

                    You said (1st post):
                    I've bricked this set while updating it after it became unresponsive so I'm looking for the EEPROM bin file in order to reprogram the EEPROM
                    i've said to you that software is not on eeprom! is on the nand flash..
                    you said:
                    I can read and write to the IC and verify data
                    so wich type of programmer do you have?
                    If it s bricked there's nothing you can do apart connect it to the PC via serial cable and try to upgrade by there.... !

                        93C46 and 93C56 EEPROM
                        by SidneyCanadas
                        I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

                        https://cdn.badcaps-static.com/pdfs/...c6e42b20d3.pdf 2

                        Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...

                        Pioneer DEX-P99rs "No EEProm " diagnostic code.
                        by dmccul2698
                        Hello, My head unit developed strange behaviors so I ran the built-in diagnostic package which returned "No EEProm". The service manual says there is no EEProm connected. I approached Pioneer and they said to swap out the DSP board. All said and good but the DSP board is $860 USD. I am hoping someone can help me

                        1). Understand the schematic and check the connections between the EEProm and DSP
                        2). Check the functionality of the EEProm

                        I don't know if this is the unit's problem but it's a place to start.

                        I have little to no electronic experience...

                        Damaged EEPROM on TV Vizio E320-A0
                        by edgarmg15
                        Hi everyone

                        I´m trying to repair a TV Vizio E320-A0 that I found in the street

                        The symptoms are it doesn't respond with remote or buttons, the LED indicator is always off and also there is no image on the TV.

                        The power supply board works fine (I probed the terminals with my multimeter) but in the main board the EEPROM doesn't works correctly because the voltage on the pins doesn't match with the parameters of the datasheet.

                        So, I´m going to replace the EEPROM with a new one, but the problem is that my programmer (CH341a)...

                        Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
                        by acedogblast
                        This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                        There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

                        Eizo CS2740 eeprom dump, search.
                        by AlexGsmMaster
                        Good day to all, I have a big problem. I can't find the eeprom dump for the Eizo CS2740 monitor. The device doesn't turn on, the indicator just lights up. It responded to connecting to the PC once. The update process started with the standard program and then disconnected from the computer. The computer doesn't detect it anymore. If anyone has an eeprom dump, please share.
