    Dell G7 7790 no display

    Hello, i have dell g7 7790 Vulcan15_N18E with i7-8750h and rtx 2070(n18e-g2-a1).
    I tried different bios but same result: laptop turn on, then first reset, then second reset and then stays on without any picture.
    Laptop react for holding power button to turn on but nothing more.
    Resistance on cpu: 3-4ohms.
    Resistance on gpu: 0.3-0.4ohms
    resistance on vram(samsung hc14): 20ohms
    Resistance on pch 1.05: 40ohms
    Laptop is charging battery normal.
    What else i can check?
