Quick summary tied to the thread: reported the laptop boots and then both the internal screen and the HDTV go black right as Windows reaches the desktop. That pattern most often points to either a graphics-driver/display-mode change when the OS loads, or a hardware/connector problem that only shows when the driver takes over from the basic video used during boot. As noted, display configuration matters, but a few targeted checks will isolate which side is failing.

Diagnostic checklist (in order)

  1. Boot into Safe Mode (Advanced Boot Options / F8). If the desktop appears there, the problem is almost certainly a driver or Windows display setting. If Safe Mode is black too, treat it as a hardware/connector issue.
  2. Boot normally with the HDTV disconnected. If the laptop desktop is normal, change the laptop’s display properties while disconnected: choose a low, standard resolution and 60 Hz refresh, set the output to duplicate/mirror, apply, then plug the TV in.
  3. If Safe Mode shows the desktop but normal boot does not, uninstall the display adapter in Device Manager, reboot, and install the latest WHQL driver recommended for the HP dv9000 series (use HP’s driver page first, then NVIDIA if needed). After reinstall, confirm a TV-friendly resolution before reattaching the HDTV.

Additional checks

  • Inspect both ends of the VGA cable and the laptop port for bent/missing pins or loose shell/grounding. Visual damage can produce intermittent signal loss that only appears after the driver switches modes.
  • Try a different external monitor (not the HDTV) or boot a Linux live USB with the HDTV connected; success there points to a Windows/driver issue.
  • If the internal display is dead even with no external devices attached and Safe Mode, consider a hardware fault (GPU, LVDS/cable, or inverter/backlight) and seek service.

These steps separate software/configuration failures from hardware faults and will suggest whether a driver reinstall, simple resolution change, or repair is required.

I assume your using Vista? What graphics card are you using?

I am thinking that the laptop isn't setup properly. You should be able to configure monitors with whatever program is used with your graphics card. You can appropriately number your monitors, set up resolutions etc...

Okay then.

On the desktop right click.
Click on NVIDIA control panel.
Then select Set up multiple displays. (Have a look a the image I have)


Here you can setup your display's(I only have one, you should have two). I would suggest disconnecting the external monitor until windows starts up. Don't forget their maybe a switch monitor button on the keyboard like 'fn F4'.

Hope this helps.
