UnBricking TV by EEPROM Reset - SamyGO
UnBricking TV by EEPROM Reset From SamyGO Here we will show you how to reset your TV by resetting the SoC EEPROM. This can be very useful in case you have bricked your TV by messing with some of its internal settings, which can easily happen if you mess around in the Service Menu. It is highly recommended to take photos of each screen in the service menu, showing your original firmware settings, before changing anything!

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" Samsung Documentation (http://www.samsung.com/us//OwnersHowToGuidePopup.do?howto_guide_seq=5306&prd_ia_cd=N0000058&map_seq=31175) This wiki entry will not help resolve a TV bricked by firmware flashing. http://wiki.samygo.tv/index.php5/UnBricking_TV_by_EEPROM_Reset#Blind_Factory_Reset

One example (from the original post of this wiki): This is Erdem. As I bricked my D series device by miss service menu setting, I search for solutions to recover it. After with help of Juzis we unbricked device with the same way of C series TVs... Here I wanted to try to let you know how the process is working. Firstly, this hack doesn't work if you bricked you device by firmware flashing... This hacks just removes service menu settings and let you give another chance to fix settings... Also you needed to find correct values for your TV after resetting NVRAM like Model / Type / Tuner / Font Color and others. It's better to have screen shots of your service menu. You can also ask help from our forums.
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. 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 U (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 (http://pdf1.alldatasheet.com/datasheetpdf/view/22813/STMICROELECTRONICS/M24512RBN6.html). In picture, white triangle shows the first pin.
