Eeprom

[tech2014]

Does anyone know anything about EEPROM on main board. I have an LG tv that has 5 EEPROM on it, is this normal. I have a plasma tv that has all the voltages present but when the main board is connected, I lose the VA and VS. I tested the SDA and SCL on all of the EEPROMS and I am not getting the normal square wave output. Do I need to replace all of them? The part number is WINBOND 25Q64BVFIG.

Re: Eeprom

The YSUS, ZSUS, YDRV module are ok? Check the PSon signal. W25Q64BVFIG is SPI FLASH memory, it is possible to have bad software or bad block/sector inside.

Re: Eeprom

What model of LG plasma tv is? To test W25Q64BVFIG you need eeprom programmer and SOP8-DIP8 adapter.
