Hello All,
I have tryed the Samsung site, but it was no help.
I did try disconnecting the lead from the power supply to the signals board and the backlights lit up and the power supply stoped cycling on and off. Has anyone a circuit for the signals board (BN41-01190a) or able to identify the eeprom

Hi,
I don't think you'll find any circuit for the main pcb, but this might help.
