Good day friend Sergio Santos, before changing the eeprom (FM24C08A) as I said check the Datasheet and gave me the following data:
Pin 1 = A0
Pin 2 = A1
Pin 3 = A2
Pin 4 = GND
Pin 5 = SDA
Pin 6 = SCL
Pin 7 = WP
Pin 8 = Vcc
According to this I checked the voltage and he gave me the following:
Pin 1, 2, 3, 4 and 7 = GND
Pin 5 = SDA = 5 v, reaches the tuner and pin 61 of N101 (8873CSCNG6V11)
Pin 6 = SCL = 5 v, reaches the tuner and pin 58 of N101 (8873CSCNG6V11)
Pin 8 = Vcc = 5 v
To all these I made the change and with the new eeprom the TV remains the same, as another test I do. GOD BLESS YOU.
