    Lenovo x1 carbon 2nd gen - LMQ-1MB 12298-2 48.4LY07.021 no displaye and it is turning

    Hi,

    I have a problem with my Lenovo x1 carbon 2nd gen - LMQ-1MB 12298-2 48.4LY07.021 .
    New bios have been flashed because the previous one was corrupted but this still didn't resolve the issue with no display. The laptop now is experiencing no display and is turning of by itself after 1-2 minutes.

    This are the voltage and resistance reading on the COILS

    L1 - 1.73V 58Ω
    L3 - 5.1V 1.7kΩ
    L4 - 3.3V 11kΩ
    L5 - 0.7V 38kΩ - when the battery is connected showing 16.4V
    L7 - 1.35V 122Ω
    L28 - 0.9V 2.06kΩ

    Any advice and help will be appreciated.

    Thanks
