LG 55LV4400	Can't Post

Greetings, This LG 55LV4400 will power up and then immediately shuts down. I have no service material. Standby, power on, and BL on voltage is good. The 12.6 volt on CN 202 appears and then drops to 0. Any help would be greatly appreciated.

EEPROM could be bad.

Something is shutting down that section of the power supply for some reason and without it the set won't work..try to unhook that wire from the connector and see if the voltage stays up, if it doesn't you have a bad power supply board <br>
