    Samsung UE55D6537 system restart after 30sec

    Time for yet another Samsung adventure...
    UE55D6537 starts up fine, everything works in 25 seconds. Then systems "hangs" and does not respond to remote.
    (The red standby led flashes when remote is pressed, but I guess this is taken care of by the small touch button and IR reciever board)
    A few more seconds, the TV restarts completely. Probably because the watchdog resets the mainboard.
    This COULD be in need of new FW or RESET but it's impossible to get the time to update the FW by USB in just 25 seconds.

    BTW, These newer Samsung's doesn't have the old service menu combination. What is the new button sequence ?

      Info - Menu - Mute - Power (from standby) doesn't work?
      Try Mute - 1 - 8 - 2 - Power (from standby)
      Don't know of any others...

          My bad. The "normal" Info .. sequence worked after all.
          Must have made some mistake at first.
          I enter the service menu and rush towards the factory reset, but nothing happens when I select it.

              One thing to check before swapping main board, all voltages stable from PSU, all LDOs OK? Freeze spray parts of board does it last longer?

                  Samsung UN40H5003 boot loop every ~8 seconds
                  by eigma
                  Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

                  Service manual: https://www.electronica-pt.com/esque...is-u8la-71272/

                  SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

                  Main board: BN94-07592P / BN97-08922R...
