    Re: KDL-40S4100 lcd help please

    I used ShopJimmy's online store to deduce that the KDL46S4100 main board I got is most likely part number 1-857-092-21 (not the alternative 1-857-092-41). The System Firmware value of "V1.021,V1.008P" has the "21" in it (presumably the 1.008P is the actual version, which does match what the main menu says and which is older than the newest 1.115). Also, the serial number reported in the factory service menu is in the correct range for the 1-857-092-21 board.

    Thus, I can deduce from ShopJimmy's store that the LCD panel that the main board is expecting is either the 46" LTY460HB10 or LTZ460HB10. There is no cross-reference anywhere I can find that shows what "LCD_AU037_1920" translates to, so I still cannot tell for sure whether the "Panel Version: LCD_AU037_1920" shown in the factory service menu is the LCD panel that the main board DETECTS that it's attached to or EXPECTS to be attached to.

      LTY460HB10 = Samsung 46" FHD Panel
      LCD_AU037_1920 = AUO 37" FHD Panel

        Thanks, tom66!

        Whoa, that's crazy! Then the 1-857-092-21 board from a 46S4100 somehow got configured with "Panel Version: LCD_AU037_1920" even though neither the 40S4100 nor 46S4100 has a 37" panel in it. I wonder what happened...

        It is probably safe to say then that the Panel Version is what the main board EXPECTS to be connected to and that it does not autodetect what it is actually connected to.
