    Hello

    Happy new year everybody.
    Problem is sometimes backlight of panel is switched on, sometimes not.
    Sometimes i can keep starting laptop and it is always on, sometimes backlight doesnt come on every time is switch it on.

    I checked output voltage of inverter: 0V.
    I replacement of inverter enough, or particular graphic card is able to speak with particular inverters only - which would require bios update?

    Original setup:
    7900 GS

    12 burned graphic cards later:
    Quatro 2500M
    other panel: LTN170W-B2 LF
    other inverter:LTN170W-B2 LF (LJ97-00690A 1A)

    Any M1710 inverter should work with any M1710 graphics card. Is that what you're asking?
