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:

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... -
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... -
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)... -
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.07-26-2025, 03:24 PM -
This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...
