    Samsung LE37A656A1FXXU dead after service menu

    Guys,
    I am real idiot and need help. I tried to switched off in service menu automatic powering up after the power suply restore, but probably has changed the config and now I cannot se anything on the screen just green noise.
    Is there chance to restore the default ?
    Thank you

    You can try the 5-6 EEPROM jumper trick.
    Locate the main EEPROM, jumper pins 5-6 and power on, remove at right time (takes a bit of practice)
    TV should fall into the default mode (colours may be wrong) so go into service menu and set up correctly.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

      Thank you.
      There are several ICs on board, is there way to locate it easily ? There are also some IC bellow shielding which is soldered. Should I remove it and look under?

        I tried this procedure on my MT8226 EMMA main board ( I found a IC7004 which I hope is the correct EEPROM) . I did this coulple time, but TV always start normály with the noise on the screeen. Does anyone knows, if the IC7004 is the correct one or what I do wrong?

          So I finally managed to get TV back into operation by switching into service menu and than blindly pressing randomly buttons ( as I had no picture ) until picture pop up. It was definitely luck, but help. Thanks to all for support.

            That's awesome and ironically funny too. I think a smart move, too. Good for you! Hurry! Go buy a lottery ticket!

              Is this the same TV with blown fuse on the inverter board?
