Blind Factory Reset
Before trying to EEPROM reset, please try a factory reset, that might revive your TV also.

Press "EXIT" button for 12 seconds (15 is better since you cannot see TV), than press "Left" and "Enter"
EEPROM
EEPROM is a short of electrically erasable programmable read only memory, which is actually a chip. There are several EEPROM chips used in Samsung TVs. All service menu settings are kept in the so called SoC EEPROM. You can delete and reprogram this chips millions time. So they are fast and reliable...


Reseting NVRAM (EEPROM)
For resetting TV, settings, you needed to remove SoC EEPROM device from TV. But it's not required. In electronic world, if you disable communication of the chip, it counts as removed. So we just needed to kill communication of SoC EEPROM. EEPROMs on Samsung TV's communicating via common i2c protocol. That protocol carries data via SDA line and send clocks via SCL line. In our situation, both blocking SCL or SDA will works. But I decide SDA.

To do this, all you have to do that feeding (connecting) GND (ground) or VCC (3.3v) to SDA line with little wire... That's all. Since this lines are HIGH (v3.3) in IDLE, its better to hold it via VCC. You can also hold this lines via GND too. But don't try to connect both GND and VCC. It will be short circuit and probably will damage your board.

Join VCC and SDA, power on TV and hold about for 20 seconds with the TV powered. It just try to read (wrong) settings from EEPROM, since it cannot read anything (refer to the warning message bellow), just start with defaults. That is what we want. Than releasing SDA line and shutting TV off will update the settings on EEPROM with null values, that TV could boot with it. After all, you can enter service menu and change the required changes.

Where do I find the SoC EEPROM chip?
Its located near CPU (SoC) at C and D series. On top, it writes some numbers and letters starting with 24256 or 24512... Here I place some screen shots from D series bellow. In my TV, 24512 EEPROM chip used. You can get the 24512 Chip Datasheet here. In picture, white triangle shows the first pin.

B Series SoC EEPROM Location
LExxB550

You have to search for eeprom on back side of mainboard. IC3001
