    Toshiba L50-B-1U8 no image before windows

    Hi!

    I have a Toshiba L50-B-1U8 that while booting it show no image. The screen turns on though.

    During this phase if I press F2 it doesn't come out of the booting process and I have to turn it off in the power button. I'm assuming it enter the bios menu, it just doesn't shows it on the screen.

    After the booting phase it starts loading windows and the image shows up normally after that. In windows everything is normal and every hardware component works fine.

    The problem is only during the booting process before loading windows.

    It was using bios version 2.0 but I downgraded it to the version 1.9 to see if it solved the problem. It didn't, still the same behavior. I've got the bios from here.

    More info about the laptop:

          Disconnect internal LCD
          Connect via HDMI and see difference.

            No image during boot with an external monitor via HDMI
            With and without internal LCD connected, tried both ways
