Can you hear the fans and other part starting as well? Since the flash light thing is showing some sort of boot, it might be a display issue.
If we are thinking it is a display issue, and not a booting issues, you can try another monitor to test with? Plug in a secondary monitor and see if you can see. If you can see a picture, you will want to reseat your internal display cable first and try again. If that isn't working it is safe to assume that the internal display cable is faulty or the screen portion itself if faulty.
Hope this helps in some way.
