No notebook display- ext. monitor OK

My dv6000 series notebook with Nvidia 7200 graphics card suddenly developed a "dead" display. Here's the story. Everything was fine until I attached the notebook to the HP docking station and then attached a 19" Samsung LCD to the dock. I loaded the Samsung driver, and natural color software. I then hit fn- f4 and a beautiful display appeared on the external monitor at the correct resolution of 1280x1024. The dv6000 has a widescreen 15.4 at 1280 x 800 (I believe). When I tried the fn- f4 to switch back to dv6000 display, it's a black screen. When I disconnect, the dock, monitor and just boot the notebook...no display. While there is no display, I can see a back lighting to the screen, and the light-dark keys have subtle effect. The screen looks black with a dim back light. Connect the external display to the notebook and up pops the image. After several hours with HP tech support (2 disconnects) and reinstalling and updating the Nvidia driver, there is still no notebook display. I also tried to work with the external display (monitor 1 & 2) without success. Any ideas or suggestions. It's still under warranty...how do I get service?

 

It's weird, because I've been reading the same problem as yours with 3 different people on another notebook forum. And all of them also had Samsung external monitors. One of the guys had to have his display changed to work.

Here's the link to the discussion, maybe you can get an idea on what to do:

Thanks, I checked out the posts on the link and they seem very similar. Assuming HP fixes the display and I can reinstall all programs, updates, etc. I am very hesitant to reattach the external monitor if somehow it destroys the notebook display. This is very frustrating, and there is nothing I could find on the Samsung website. I have a very old notebook, and I think I try attaching the monitor to it and see what happens; however, the video won't provide sufficient resolution. It I can find an answer to this situation, I think I'll try attaching a 4 year Sony CRT to the repaired notebook. It's not my preference but it has worked very well for photo editing and it should be easy to color calibrate compared to an LCD. I'll then attach the Samsung LCD to my old desktop and at least obtain some use from it.
