    Re: Samsung QE65Q60TAUXZT New Mainboard but wrong colours

    there is a page where you can see all input settings, can you show the differences? Anyway maybe the service manual don't covers all the differences in settings, if i remember there is a page where you can set color settings for each input but it seems that it does not recognize a valid input so the inputs page must be seen, in second place a complete settings data copy must be made but i surely don't know how, i have never played that long with a Samsung, maybe the new mb has something wrong in settings files, so a new board is required..

        Try also even a software update, i remember that on some newer Samsung there is also a spi memory on the panel's boards, maybe that must match some data with the tcon section.. i don't know what the hell it stores, maybe them needs a pairing procedure like in Sony..

        in post #16 i see on the option page at voice Writing front color there is no signature, what happens if you select that line? Is that selectable or is read only?

          Do the sticker numbers match on both the mainboards? if you followed option byte instructions of lotus pdf it should have worked, guess it's possible they sent you a defective board.

              It is not a requirement apparently as it is empty in both boards

                These are both stickers and the noticed difference

                  Try to look through, clean the contacts on the LVDS cable on both sides.

                      Integrated T-CON.

                      I have sent information to Samsung local agent whom are to verify if board is defective or not. Hope will get a reply soon as my client wants his tv back.

                            if the problem was electrical at the lvds port the tv would not tell failure for the tv mode (input) i guess, i think that this board has some problem at main software, totally waste of time..

                              Update:
                              A new main board arrived and all is now fine. The connected new Pcb displayed the correct colors immediately even before programming of panel type, model , local etc.

                              Thanks ALL for helping me out, as usual!

                                  Were the sticker numbers on the new board that worked the same as the replacement that did not, meaning was the last letter the same or was it the same as the mainboard you have that already worked or different yet?

                                    Trying to discern if the board that did not work was a mismatch or just defective.

                                      Hi,

                                      The board received by ordering with the full model number had a different BN number.
                                      Received BN94-15427H and worked fine immediately.
