Samsung UN40J6300AFXZA Main Board Repair

[johniwad]

I know this Samsung UN40J6300AFXZA BN94-08247E main board is bad. Screen is black with sound and back lights but no picture. I replaced the T-Con board with no change. I cannot find schematics for this board. Bought a similar main board for a different Samsung TV thinking I could just swap out the flash/eeprom chips. I swapped eeprom chip but replacement board show no signs of life. Should I swap out eemc chip or could the problem be in the SDP1415 SOC? Any help or advice is greatly appreciated.

Original Board: BN94-08247E
Code: BN41 -02353A
Mode: BN41 - 02353

Replacement Board: BN41-02353A
Code: BN41 -02353A
Mode: BN41 - 02353

Did you check the LVDS on the main board with on an oscilloscope? voltage checks on panel power etc?

I seem to have all the proper voltages and I did check LVDS with my oscilloscope and there is no signals from main board to T-Con. I was thinking maybe the SDP1415 SOC may have a few balls that has lifted or is partially faulty.
