    Toshiba C50-A, AC light good, Power on blinks ~10 seconds, wifi light 'flickers'

    Toshiba laptop, no obvious damage (physical or liquid).

    Plug power in, and the AC-in light glows white.

    Try turn on and the power-ON LED illuminates for about 2 seconds before going out for about 10 seconds, endless cycle/loop. Each time the power-ON LED activates the wifi orange LED flickers on for about 1/100th of a second, enough to notice but not much more.

    Tried with fresh RAM, replaced CMOS battery, no peripherals attached.

    Tried with LVDS disconnected as well.


    EDIT/UPDATE:

    If I remove the CMOS battery, it can be switched on and stay on but no boot.
    It has an 8GB DDR3L SODIMM in it, if I replace it with almost any other DDR3L (even at the same speed) it goes back to the slow blink. The only other 3L module that worked was a different branded 4GB unit.
    If I put the CMOS battery back in it'll go back to blinking after the first power cycle.

    Problem with the SPI bus perhaps?

      Whole area looks clean and no shorts on any pins.

      Am wondering if maybe something is hanging the bus preventing the system from POSTing.

      I don't even get an LCD backlight enable.

        LG 23MP55HQ LED Monitor turns off after a few seconds or flickers.
        by Rick_1234
        Good evening, gentlemen.

        I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

        To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.
