    Monitor Led Samsung S22D390H
    Mainboard: BN94-07379A or BN97-08290A

    Nothing turns on but the external power supply works fine (I also tried to replace it) and the power comes to the mainboard. It had started to stay on all the time without turning off the touch buttons, then by cutting off the power it no longer turned on. I think the SPI is corrupted, does anyone have the dump?
