    Diagnose a Samsung UE43NU7199UXZG

    Hi,

    i am asking for some help / information for a diagnostic of a Samsung TV.

    The TV (UE43NU7199UXZG) works as usual, but sometimes it´s restarting the complete TV.

    Most of the day the TV is working fine and it only reboots once a day.
    Sometimes it´s working fine for more than a week.
    And the other day it´s rebooting after 30 min.

    But it´s not reproducable-

    So the reboot intervals are like
    • 30min, 4-5h, 2 days, 1 week


    Can this be a problem of the Power Supply (Bad Caps) or some software bug?

    Thanks in advance

    Jürgen

      Power supply and mainboard are one, bad caps I've never seen with this model. A reboot could be a EMMC or processor problem but also a power line which is a bit to low. Very difficult to find when the problem is not continous.
