    by THXFX
    Hi I need help with a Samsung un43nu7100 BN94-13191C/BN41-02635A with boot loop problem even with tcon jumper.
    I've already try tape method and same happen, if I disconnect both flex from mainboard to panel tv boots normal even I hear Samsung sound.
    When I solder jumper to make t-con work with or without panel or panel cables connected it still reboot or power cycling.
    What I noticed is that there's no voltage in VHG, HAVDD, PANEL_3.3V, AVDD_17V or 12v near dc-dc chip.
    I check capacitors and diodes and didn't find any short IN MAINBOARD.
    Measured all power supply...

    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...

    Samsung UE75TU6905 reboot loop
    by brkie
    I have a Samsung UE75TU6905 from 2021, with a maximum of 10 hours of usage as it has been used as a presentation TV in the office. It started rebooting, the picture disappears, the sound continues for 2-3 seconds, and then it restarts (Samsung logo with Tizen OS), after which it returns to the previous activity. I tried disconnecting HDMI, antenna, WiFi, and using different power outlets, and it seemed to improve (or so I thought). Before, it happened occasionally, but now it happens all the time, so the TV stays on for a maximum of 30 seconds.

    I read on Samsung's website (reviews)...
