No display on laptop screen. Help

  1. Hello,
    First off, here are the specs.

    Toshiba A215-S4817
    2Gig memory
    ATI Radeon X1200 graphics card
    160GB HDD
    15.4" LCD monitor
    Windows Vista Ultimate

    Heres the problem. I recently received "a very nice blue screen" after trying to play Spider-Man 1. After restarting, no display at all. I hooked up the laptop to an external device (widescreen tv). The dislay shows up perfectly on the tv, on the laptop screen nothing(by the way I tried the flashlight trick) its definitely not the backlights fault. I looked in the display settings, it shows only the tv is connected. No signs of the laptop display on there. The computer works perfectly as though nothing happened. I tried reinstalling and uninstalling the video drivers too, to no avail. I checked also to see if the laptop screen was connected securely, it was.

    When restarting the computer,there was no "windows has recovered from an error" message. I also checked in the Problems&Solutions part, couldn't find anything related to this problem, as the latest problem on there was a week ago. All that happened was a blue screen (an unusual one at that) saying something about "check video BIOS settings" and Windows has stopped to prevent from an error (this time without any code.

    What should I do (before going to a local repair center) ? I am a pretty good expert on tech stuff anyway.
