  • Screen appears black (with backlight on) when turned on without the LVDS cable connected.

    Signals after the level shifter still seem off. Signals before it seem fine.

    (Yellow: GSP signal before level shifter used as trigger, Purple: GCK1-GIP after level shifter).

  • None of the clock signals (GCK1-GIP to GCK4-GIP) are shorted , they all measure about 400 k to ground.

    I believe I've narrowed down the issue to the level shifter (IC2), a Novatek NT50413S.

    The signals before it are good (GSP and GCK), as shown below. I have a nice 60 hz signal on GSP with the screen connected to a camera's hdmi out, and the GCK frequency (67.47 KHz) seems about right for 1 pulse per row (not that I've counted them).

    MSI Optix G241 - Lines

    Hi,

    I have an MSI Optix G241 monitor that basically displays gibberish (see below). For context, I am a well-equipped hobbyist that dabbles in electronics and has repaired more than a few things, but I am not a professional nor have I formally studied electronics.

  • Hello from Panama, Central America.

    I've repaired a couple of personal devices in the past, but I'm stumped with a MSI monitor, so I'm joining the club.
