This is a TV I had for a while. I have narrowed the fault down to the motherboard and I want to reprogram the EEPROM. Thing is I can't find any info on the EEPROM which is ic2004. I uploaded pics and a service manual.
Sharp LC-40LE820UN not coming on

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... -

by dmccul2698Hello, 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...6 Photos-

by acedogblastThis 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... -
by BiruslapioI've shearched before posting this, and found dozens of different ways to hook up multiple types of EEPROM to an Arduino Uno, so I do not know which one is correct.
I need to learn this so I ended up with a Philips TV 32PFL3008D which has corrupted memory, the IC is U402, 25Q64FVSIG, I have the 3MB .bin file, how to hook up an ATMEGA328P to this memory and what code do I need?... - Loading...
